Researchers inspect gamma-ray flares of the blazar 3C 279

Chinese astronomers studied the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. They used NASA's Fermi spacecraft to do so. The study's findings were published in the Publications of the Astronomical Society of the Pacific. The study...

Short gamma-ray bursts traced farther into distant universe

The galactic origins of 84 short gamma-ray bursts (sGRBs) — produced by the collision of two neutron stars. These have now been identified in the most comprehensive inventory to date. To identify the sources of these sGRBs, a team led by Penn State astronomers...

Gamma-ray pulsations detected from pulsar PSR J1835−3259B

Using NASA's Fermi space telescope, Chinese astronomers investigated PSR J18353259B, a newly discovered millisecond pulsar. As a result, they discovered gamma-ray pulsations coming from this source. The discovery is detailed in a paper published on the arXiv pre-print server on June 27. Pulsars are rotating...
