A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays. Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in ...

The findings, published in The Astrophysical Journal, provide fresh insights into ultraluminous X-ray sources (ULXs) — among the brightest and most enigmatic objects known in astrophysics.

An international research team led by scientists from the Technion Faculty of Physics presents a first-of-its-kind measurement of cosmic rays located at the core of the galactic nebula Barnard 68. The ...

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

High energy astrophysics probes the most energetic phenomena in the Universe, from explosive supernova remnants to the powerful outflows near compact objects. A central focus of this field is the ...

Neutrino astronomy has emerged as a pillar of high-energy astrophysics following the discovery of a diffuse astrophysical neutrino flux by IceCube. The ...

Scientists are baffled by weird signals detected beneath Antarctica. A cosmic particle detector designed to pick up rays from space instead recorded a series of bizarre signals from under the ice.

Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmic phenomenon. The ...
