The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 18 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. We thank you in advance for your valuable feedback.

Fermi's GBM Spots Merging Neutron Stars

At 12:41 UT on August 17, 2017, the Gamma-ray Burst Monitor (GBM) on board NASA's Fermi Gamma-ray Space Telescope automatically triggered on a gamma-ray burst and classified it correctly, just as it does about 240 times per year. This particular trigger, however, had a unique friend: a near-simultaneous gravitational-wave detection from the LIGO-Virgo global network of interferometers.

'Extreme' Telescopes Find the Second-fastest-spinning Pulsar

By following up on mysterious high-energy sources mapped out by NASA's Fermi Gamma-ray Space Telescope, the Netherlands-based Low Frequency Array (LOFAR) radio telescope has identified a pulsar spinning at more than 42,000 revolutions per minute, making it the second-fastest known.

Gamma-ray Telescopes Reveal a High-energy Trap in Our Galaxy's Center

A combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, suggests the center of our Milky Way contains a "trap" that concentrates some of the highest-energy cosmic rays, among the fastest particles in the galaxy.

Stage-I Selection Complete for Cycle-10 GI Program

The stage-I selection process for the Fermi Cycle-10 Guest Investigator program has been completed. There were a total of 43 new programs selected for stage I out of 183 proposals submitted. A list of the selected programs, including the PIs, titles and abstracts is available on the FSSC web site.

NASA's Fermi Catches Gamma-ray Flashes from Tropical Storms

About a thousand times a day, thunderstorms fire off fleeting bursts of some of the highest-energy light naturally found on Earth. These events, called terrestrial gamma-ray flashes (TGFs), last less than a millisecond and produce gamma rays with tens of millions of times the energy of visible light.

NASA's Fermi Finds Possible Dark Matter Ties in Andromeda Galaxy

NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

GBM Response Generator Software

The Fermi GBM team has provided a portable version of their response matrix generation software and associated calibration files. Previously, this was available to the public only via an interactive web interface. The response file generator facilitates production of response files for a GBM triggered event or for an arbitrary source location at an arbitrary time for each of the GBM detectors. The intent is to better facilitate studies such as candidate, non-triggered GRBs or solar flares, TGFs and searches for electromagnetic counterparts to gravitational waves. To obtain the software please visit the FSSC GBM data analysis web page.

NASA's Fermi Sees Gamma Rays from 'Hidden' Solar Flares

An international science team says NASA's Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from these events. This apparent paradox is providing solar scientists with a unique tool for exploring how charged particles are accelerated to nearly the speed of light and move across the sun during solar flares.

NASA's Fermi Discovers the Most Extreme Blazars Yet

NASA's Fermi Gamma-ray Space Telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by supersized black holes. Light from the most distant object began its journey to us when the universe was 1.4 billion years old, or nearly 10 percent of its present age.
