Fermi Data Tantalize With New Clues To Dark Matter

A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the Harvard-Smithsonian Center for Astrophysics (CfA), the Massachusetts Institute of Technology (MIT) and the University of Chicago have developed new maps showing that the galactic center produces more high-energy gamma rays than can be explained by known sources and that this excess emission is consistent with some forms of dark matter.

Second GBM Catalog of Gamma-Ray Bursts Available in HEASARC Browse

The Fermi Science Support Center and the GBM Team are pleased to announce the availability of the second GBM catalog of Gamma-Ray Bursts (GRBs) in the HEASARC browse interface. The catalog will soon appear in the Astrophysical Journal (Supplement Series). This catalog is in two parts: a general description (A. von Kienlin et al., http://arxiv.org/abs/1401.5080) and a spectral analysis (D. Gruber et al., http://arxiv.org/abs/1401.5069). The general catalog includes 953 GRBs that triggered GBM between 2008-07-12 and 2012-07-11. The spectral catalog reports spectral analyses of 943 GRBs, including revised analyses of the GRBs in the first catalog, from 2008-07-12 to 2010-07-11. Data from these catalogs are now available at the HEASARC in searchable tables via the Browse interface.

With A Deadly Embrace, 'Spidery' Pulsars Consume Their Mates

Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.

NASA Spacecraft Take Aim At Nearby Supernova

An exceptionally close stellar explosion discovered on Jan. 21 has become the focus of observatories around and above the globe, including several NASA spacecraft. The blast, designated SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type Ia supernova to occur during the life of currently operating space missions.

Reminder: Cycle-7 GI Proposals are due on January 31, 2014

Proposals to participate in the Fermi Cycle-7 Guest Investigator Program are due by 16:30 EST January 31, 2014. For additional details and instructions on how to propose please refer to the Proposals page of the FSSC web site and to the Fermi Amendment to the 2013 ROSES NRA which is hosted by the NSPIRES web facility. We strongly encourage prospective proposers who have not already done so to review these documents as there are several changes to the program relative to past mission cycles.

NASA's Fermi Makes First Gamma-ray Study of a Gravitational Lens

An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.
