Tidal debris detected in a nearby galaxy group

Using the MeerKAT telescope, an international team of astronomers has identified wide-spread tidal debris in a nearby galaxy group known as NGC 7232. The newly found structure is composed of cold neutral atomic hydrogen and ...

A new window to see hidden side of magnetized universe

New observations and simulations show that jets of high-energy particles emitted from the central massive black hole in the brightest galaxy in galaxy clusters can be used to map the structure of invisible inter-cluster magnetic ...

Research investigates radio galaxy 3C 84

An international team of astronomers has conducted a detailed kinematic study of a radio galaxy known as 3C 84. The research sheds more light on the properties of this source and its connection to gamma-ray emission. The ...

Cosmic lens reveals faint radio galaxy

Radio telescopes are the world's most sensitive radio receivers, capable of finding extremely faint wisps of radio emission coming from objects at the farthest reaches of the universe. Recently, a team of astronomers used ...

Delayed radio flares from a tidal disruption event

A team of researchers from the Hebrew University of Jerusalem (HUJI) led by Dr. Assaf Horesh have discovered the first evidence of radio flares emitted only long after a star is destroyed by a black hole. Published in the ...
