Spinning stars shed new light on strange signal coming from galactic center

The Australian National University (ANU) researchers have found an alternative explanation for a mysterious gamma-ray signal coming from the center of the galaxy. It was long claimed as a signature of dark matter. Gamma-rays are the form of electromagnetic radiation with the shortest wavelength and...

Thermal electrons play key role in determining emissions from gamma-ray-burst afterglows

The presence of unusually energetic gamma rays seen in some afterglows from intense gamma-ray bursts (GRBs) could be explained by a new mathematical model developed by RIKEN researchers. This finding could help to shed light on the origin of GRBs. A GRB is a spectacular...

Cosmic spider is the source of powerful gamma-rays

Astronomers have discovered the first example of a binary system by using the 4.1-meter SOAR Telescope in Chile. Here a star in the process of becoming a white dwarf is orbiting a neutron star. This star has just finished turning into a rapidly spinning...
