Supermassive black holes in the universe swallow gas around them. The infalling gas is called black hole accretion flow. In a study published in Nature Astronomy, the group led by Prof. YUAN Feng at Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, together...

Magnetars are bizarre objects—massive, spinning neutron stars with magnetic fields among the most powerful known, capable of shooting off brief bursts of radio waves so bright they’re visible across the universe. A team of astrophysicists has now found another peculiarity of magnetars: They can emit...

Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving energetic particles, mostly hydrogen ions called protons, the lightest and most abundant elements in...

It is generally believed that double-peaked broad emission lines originate from an elliptical disk. Appearance or disappearance of the broad Balmer emission lines correspond to type 1 and type 2 active galactic nuclei (AGNs), respectively. Hence, the name changing-look AGN. The physical origin of the...

Astronomers from the National Radio Astronomy Observatory discovered the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy’s nearly-naked supermassive black hole to emerge and speed away at more than 2,000 miles per second. The fascinating discovery was...
