Back in 2009, gamma-ray data from the Fermi-Large Area Telescope revealed an unexplained, apparently diffuse, signal from the center of the Milky Way. The origin of this “Galactic Center Excess” has ...

A Northwestern University-led team of astrophysicists has developed the first-ever full 3D simulation of an entire evolution of a jet formed by a collapsing star, or a “collapsar.” Because these jets ...

New Delhi: Astronomers have spotted a source of gamma-ray bursts (GRBs) unlike any seen previously. Typically, GRBs are produced by catastrophic events such as the violent deaths of stars or tidal ...

Old and fast spinning neutron stars called millisecond pulsars could be responsible for an unexplained signal from the center of our Milky Way, reports a team of astrophysicists in a new study ...
