Unprecedented gamma-ray burst explained by long-lived jet

Last year, Northwestern University researchers reported new observational evidence that long gamma-ray bursts (GRBs) can result from the merger of a neutron star with another compact object (either another neutron star or ...

Scientists map gusty winds in a far-off neutron star system

An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that ...

Astronomers discover helium-burning white dwarf

A white dwarf star can explode as a supernova when its mass exceeds the limit of about 1.4 solar masses. A team led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching and involving the University of ...

Hundreds of new high-redshift quasars discovered

An international team of astronomers reports the detection of more than 400 new high-redshift quasars using the Dark Energy Spectroscopic Instrument (DESI). The discovery, published February 3 on the arXiv preprint server, ...
