Chandra Sees Supernova SN 1006 in Exquisite Detail – Sci

Astronomers using NASA’s Chandra X-ray Observatory have captured the most detailed view yet of the supernova SN 1006.

X-ray image of the SN 1006 remnant. Low, medium, and higher-energy X-rays are colored red, green, and blue respectively (NASA / CXC / Middlebury College / F. Winkler)

The supernova SN 1006 was probably seen first on April 30, 1006, according to records from China and Japan. It was of apparently yellow color, far brighter than Venus and visible during the daytime for weeks.

In the 1960s, astronomers were able to launch instruments and detectors above Earth’s atmosphere to observe the Universe in wavelengths that are blocked from the ground, including X-rays.

SN 1006, located in the constellation of Lupus about 7,200 light years away, was one of the faintest X-ray sources detected by the first generation of X-ray satellites.

In the new Chandra image, low, medium, and higher-energy X-rays are colored red, green, and blue respectively.

The image provides new insight into the nature of the supernova, which is the remnant of a so-called Type Ia supernova.

By examining the different elements in the debris field – such as silicon, oxygen, and magnesium – scientists may be able to piece together how the star looked before it exploded and the order that the layers of the star were ejected, and constrain theoretical models for the explosion.

Scientists are also able to study just how fast specific knots of material are moving away from the original explosion. The fastest knots are moving outward at almost eleven million miles per hour, while those in other areas are moving at a more leisurely seven million miles per hour.

The findings were presented at the 13th Meeting of High Energy Astrophysics Division of the American Astronomical Society in Monterey, CA.

Urry elected president of Astronomical Society

Physics professor Megan Urry — an advocate for female leadership in the science community — has been elected the next president of the American Astronomical Society.

Members of the AAS elected Urry to the position in early February. Though she will begin her two-year term in June 2014, she will spend the next year as president-elect preparing for her role. The first Yale professor elected to the position, Urry will succeed Columbia University astronomy professor David Helfand. Urry’s colleagues at Yale said she has been a strong advocate for increased gender diversity in the field of astronomy, a goal Urry said she intends to continue pursuing once she assumes her presidency.

Urry, who learned about her nomination for the presidency last summer, said she decided to run because she knew her term as Yale Physics Department chair was ending and she felt she could handle new responsibilities. She was required to submit a candidacy statement and was then elected by the 7,500 members of the AAS through an online voting system. During her tenure as AAS president, Urry will remain at Yale and continue to teach classes.

Though Urry is not the first female to serve as AAS president, she said she is excited that her peers elected a female leader. An advocate for gender equity, Urry has previously served as chair of the AAS Committee on the Status of Women, which performs outreach to encourage women to enter the field of astronomy.

“She has done more for the position of women in astronomy than anyone ever has,” said Joan Schmelz, current chair of the AAS Committee on the Status of Women. “Here at the committee, we say that in terms of creating progress, we’re standing on the shoulders of giants — we’re standing on Meg’s shoulders.”

Urry’s colleagues at Yale said she has also advocated for diversity within the University’s Physics Department. Physics professor Volker Werner said Urry has always emphasized the importance of female leadership at faculty meetings.

“Diversity is so important for the field of science because we want to generate the best and most creative ideas,” Urry said. “It’s exciting to see how much progress there’s been, because when I first entered the field there were very few women astronomers.”

During the next year while Urry serves as an incoming president, she plans to meet with professionals in the field of astronomy to formulate the agenda for her presidency. She said she will build on relationships she has forged during her active involvement with AAS as a member of its governing council and nominating committee. Her plans also include monitoring the federal budget to learn about limitations on funding for scientific research and expanding on her previous work to promote different types of diversity within her field, she added.

Urry said presidential responsibilities include overseeing the AAS’s leadership council, directing educational programs and advocating for federal funds for astronomy.

“Astronomy can be a more difficult field to advocate for because other sciences are more connected to people’s everyday lives,” Urry said. “But I hope to show that astronomers are exploring crucial issues, like the role humans play in the cosmos.”

Urry’s election is not her first recognition from AAS this year -— in January, she was honored with the George Van Biesbroeck Prize, AAS’s major annual award for service in the field of astronomy. The award recognized Urry’s scholarly research as well as her devotion to advancing female participation in scientific disciplines.

The American Astronomical Society was founded in 1899.

New Astronomy Thesaurus Could Help Future Research Projects

Lee Rannals for redOrbit.com – Your Universe Online

A new astronomy thesaurus called the Unified Astronomy Thesaurus (UAT) will help improve future information discovery for researchers.

The American Institute of Physics (AIP) and IOP Publishing (IOP) collaborated on the new thesaurus, making it a gift to the American Astronomical Society (AAS).

AAS will be making the UAT freely available for development and use within the astronomy community, while ensuring the thesaurus remains relevant and useful.

Further development of the thesaurus will be done by the John G. Wolbach Library at the Harvard-Smithsonian Center for Astrophysics in collaboration with the Astrophysics Data System (ADS) and the International Virtual Observatory Alliance (IVOA). The collaborative effect by these institutions will help to enhance and extend the thesaurus to ensure that it continues to meet the needs of the astronomy community.

Adopting the UAT within the ADS will result better linking with the astronomer research journal articles through a common vocabulary, helping to improve the accuracy of information discovery.

Creating the UAT is a result of the combination of two separate initiatives to develop thesauri as part of semantic enrichment projects by AIP and IOP.

Thousands of resources are being published each year in the field of astronomy, and these kinds of tools can be vital for researchers to continue finding relevant information quickly and helping to improve the discoverability of research.

Access Innovations Inc, a privately held company that specializes in information management and database creation products, is working to combine the thesauri.

“It’s both generous and foresighted for AIP and IOP to donate this work to the community, at a time when so much attention is focused on enabling semantic capabilities in scholarly research and communication,” Chris Biemesderfer, Director of Publishing at AAS said of the gift.

“The AAS is grateful to the publishers for the timely contribution. It’s exciting for the development team to receive a product that is as well thought through as this thesaurus, and the Society is proud to support the research community through partnerships like the UAT,” Biemesderfer added.

Scientists who have helped further our understanding of cosmic phenomena — from gamma-ray pulsars to galaxy formation — have been awarded top prizes from the American Astronomical Society. The following are recipients of the 2013 awards, announced by AAS this week:

Kenneth C. Freeman, an Australian National University astronomer who has studied the structure and evolution of galaxies, won the AAS’s top award, the Henry Norris Russell Lectureship, for a “lifetime of seminal contributions” in the field.

“Through his many PhD students and his generous interactions with countless colleagues, his influence on galactic and extragalactic astronomy has extended far beyond his own research,” AAS officials said of Freeman.

Jason Kalirai, of the Space Telescope Science Institute, was honored for his work in stellar and galactic astrophysics. Among other achievements, he devised new methods to measure the age of the Milky Way galaxy using white dwarf stars and described the fraction of mass that stars lose over their lives. Kalirai, who is 34, received the Newton Lacy Pierce Prize for outstanding achievement in observational research by an early-career astronomer.

“Being a professional astronomer is the most rewarding profession in the world,” Kalirai said in a statement. “I get to use some of the most advanced tools that humans have ever created to address the universe’s biggest mysteries. It doesn’t get cooler than that!”

Eiichiro Komatsu, of the Max Planck Institute for Astrophysics, was awarded the Lancelot M. Berkeley – New York Community Trust Prize for Meritorious Work in Astronomy. Komatsu’s 2011 report that placed tight new constraints on the standard cosmological model was the most highly cited astronomy paper last year, according to AAS.

For his theoretical work on how massive stars are formed, Mark Krumholz, of the University of California, Santa Cruz, was given the Helen B. Warner Prize for a significant contribution to astronomy by an early-career scientist.

The Annie Jump Cannon Award for outstanding research and promise for future research by a woman went to Sarah Dodson-Robinson, who studies the formation of planetary systems and teaches at the University of Texas, Austin.

Caltech’s Keith Matthews was recognized with the Joseph Weber Award for instrumentation for his achievements in infrared astronomy at the Palomar and Keck observatories. Among other feats over his career, Matthews’ NIRC2 camera in the Keck 2 telescope allowed scientists to characterize supermassive black hole at the center of our galaxy.

The Dannie Heineman Prize in Astrophysics for exceptional work by mid-career astronomers went to Rutgers University’s Rachel Somerville for her scholarship on galaxy formation and evolution.

“I am thrilled and deeply honored to be awarded the Heineman prize,” Somerville said in a statement. “I have come to realize that the knowledge we seek is so much more meaningful because we share the process and the insights with friends and colleagues, and this kind of endorsement from my peers is the most gratifying recognition that I can imagine.”

Alice Harding of NASA’s Goddard Space Flight Center and Roger W. Romani of Stanford University were honored for their work on a theoretical framework for understanding gamma-ray pulsars, which are rotating neutron stars that emit bursts of electromagnetic energy. They were given the 2013 Rossi Prize for their contributions to high-energy astrophysics.

ANU professor awarded top American astronomy prize

Australian astronomer Professor Ken Freeman has been awarded the American Astronomical Society’s top prize.

The prestigious Henry Norris Russell Lectureship was awarded to Professor Freeman for his work exploring the structure and dynamics of our Galaxy and other galaxies.

Professor Freeman, who has worked in the Research School of Astronomy and Astrophysics at Australian National University for the past 40 years, said he was honoured to receive the award.

“I never really expected that this would come off. If you look at the list, the prize has been going since 1946, it’s a bit of a who’s who of astronomy.”

ANU Vice-Chancellor Professor Ian Young congratulated Professor Freeman on the award.

“Professor Freeman has played a pivotal role in directing the course of astrophysical study both in Australia and internationally,” Professor Young said

“He is a deserving recipient of this prestigious award.”

The American Astronomical Society said Professor Freeman’s generous interactions with PhD students and countless colleagues meant his influence on galactic and extragalactic astronomy had extended far beyond his own research.

Professor Freeman is currently leading a team of astronomers seeking to map out how our the Milky Way was assembled.

“We’re at a very exciting point in that now because we’re about to start the big observational survey that we need to do this,” he said.

The team will use a $15 million instrument to measure the chemical properties of stars, trying to find groups of stars that were born together, in a process Process Freeman called “chemical tagging”.

“It’s never been done before so were quite excited about it.”

Professor Freeman was awarded the Prime Minister’s Prize for Science last year.

"Super Bowl of Astronomy" Ascends onto Long Beach with New Discoveries

“Super Bowl of Astronomy” Comes to Long Beach with New Discoveries

Details

By Brian Addison

 | Wednesday, 09 January 2013 16:10

The American Astronomical Society (AAS) holds two meetings each year—and its winter one is its largest, with 2,800 astronomers, educators, students, and others intrigued by the galaxies beyond will attend this year’s 221st meeting right here in Long Beach.

Having started on Sunday and running through to this Thursday, some 1,900 presentations and talks will span through the field’s most impressive work done over the past year.

For example, Francois Fressin of the Harvard-Smithsonian Center for Astrophysics, presented on Monday his research in finding the “second Earth” since he discovered that within 17 percent of stars sits an Earth-sized planet in an orbit closer than that of Mercury. Using data from NASA’s Kepler spacecraft, Fressin’s work posits the Milky Way as home to some 17 billion Earth-sized worlds.

“We found that the occurrence of small planets around large stars was underestimated,” said Fressin, noting that every time someone looks up at a star, nearly every single one is home to a planetary system.

In a similar vein, Christopher Burke of the SETI Institute—also analyzing data from NASA’s massively influential Kepler Observatory—talked not just of the “explosion of planetary knowledge” thanks to Kepler, but specifically the discovery of KOI 172.02, one of 461 new planet candidates. To put that number in perspective, from 5000 B.C.E. to 1992 C.E., we added only four additional planets to our knowledge, from five to nine. In addition to the latest 461 discovered by the Kepler mission recently, the nearly four-year orbit of the spacecraft has brought into knowledge 2,740 worlds orbiting some 2,036 stars.

The KOI 172.02 “exoplanet”—any planet body that sits outside our own solar sytem—is slightly larger than Earth and circles a sun just over 100 days more than our own. The key: its distance is just right for liquid water, thereby making it the closest planet similar to our own that anyone has ever discovered.

“There is no better way to kickoff the start of the Kepler extended mission than to discover more possible outposts on the frontier of potentially life bearing worlds,” said Burke.

Yesterday, Fiona Harrison of CalTech in Pasadena, showed off a stunning image from NASA’s NuSTAR spacecraft, whose mission was to help provide researchers a better understanding of how galaxies are created and how black holes grow.

The image shows supernova Cassiopeia-A exploding some 11,000 light-years from Earth, where light from the massive explosion reached visibility from Earth about 300 years ago.
