RVs for galaxies in GRS0917+75 region
Listed in IVOA Registry (Virtual Observatory)
Several author have studied the giant radio source GRS0917+75, but its origin remains unclear.
Description
This source is unusual, because of its large size and its location outside a rich cluster of galaxies. We aim to understand and discuss the properties and nature of this source and its connection to the environment.
We conducted optical observations to obtain new spectroscopic data. We also acquired a LOFAR image at 144 MHz to derive information at low radio frequency. Moreover, we performed a new analysis of archival VLA data in the L and C bands for a multifrequency study of the source properties in the radio band.

From the observational data, we classify GRS0917+75 as a giant radio galaxy with a size of 1.5Mpc and an estimated age of about 100 Myr. The optical parent galaxy is a bright low-excitation radio galaxy, the brightest member of a very poor group belonging to a large supercluster. GRS0917+75 is a peculiar low-power Fanaroff-Riley Class I giant radio galaxy with a bright central emission but no jet-like features.
The existence of giant radio galaxies such as GRS0917+75 could explain the origin of relativistic particles and magnetic fields in low-density environments.
