Remarkable flares from the galactic center

Sagittarius A* (Sgr A*), the supermassive black hole at the center of our Milky Way Galaxy, is 100 times closer to us than any other SMBH and therefore a prime candidate for studies of how matter radiates as it accretes onto ...

The most distant radio galaxy discovered

An international team of astronomers has detected a new high-redshift radio galaxy (HzRG). The newly identified HzRG, designated TGSS1530, was found at a redshift of 5.72, meaning that it is the most distant radio galaxy ...

Black holes play hide-and-seek in low-luminosity radio galaxies

Every galaxy is thought to harbor a supermassive black hole in the center, or nucleus, of the galaxy, and in active galaxies this black hole is fed by infalling matter. This "central engine" is typically surrounded by dusty ...

Astronomer composes galactic jazz

A new musical composition expressing the movement of gases through the galaxy as musical notes, "Milky Way Blues" by astronomer Mark Heyer, a research professor at the University of Massachusetts Amherst, will be featured ...

North, east, south, west: The many faces of Abell 1758

Resembling a swarm of flickering fireflies, this beautiful galaxy cluster glows intensely in the dark cosmos, accompanied by the myriad bright lights of foreground stars and swirling spiral galaxies. A1758N is a sub-cluster ...

Seven new giant radio galaxies discovered

(Phys.org)—Mexican astronomers report the discovery of seven new large extragalactic radio sources called giant radio galaxies (GRG). The GRGs were found by visual inspection of radio images provided by two astronomical ...
