The origin of the X-ray, radio and HI structures in the NGC 5903 galaxy group
Ewan O'Sullivan, Konstantinos Kolokythas, Nimisha G. Kantharia +3
The NGC 5903 galaxy group is a nearby (~30 Mpc) system of ~30 members, dominated by the giant ellipticals NGC 5903 and NGC 5898. The group contains two unusual structures, a ~110 k…
The Complete Local Volume Groups Sample - I. Sample Selection and X-ray Properties of the High-Richness Subsample
Ewan O'Sullivan, Trevor J. Ponman, Konstantinos Kolokythas +7
We present the Complete Local-Volume Groups Sample (CLoGS), a statistically complete optically-selected sample of 53 groups within 80 Mpc. Our goal is to combine X-ray, radio and o…
NGC 741 - Mergers and AGN feedback on galaxy group scale
G. Schellenberger, J. M. Vrtilek, L. David +5
Low mass galaxy cluster systems and groups play an essential role in upcoming cosmological studies such as those to be carried out with eROSITA. Though the effects of active galact…
Saraswati: An Extremely Massive ~ 200 Megaparsec Scale Supercluster
Joydeep Bagchi, Shishir Sankhyayan, Prakash Sarkar +3
Here we report the discovery of an extremely massive and large supercluster (called Saraswati) found in the Stripe 82 region of SDSS. This supercluster is a major concentration of…
AGN feedback with the Square Kilometer Array (SKA) and implications for cluster physics and cosmology
Asif Iqbal, Ruta Kale, Subhabrata Majumdar +5
AGN feedback is regarded as an important non-gravitational process in galaxy clusters, providing useful constraints on large-scale structure formation. It modifies the structure an…
Discovery of Giant Radio Galaxies from NVSS: Radio & Infrared Properties
Pratik Dabhade, Madhuri Gaikwad, Joydeep Bagchi +3
Giant radio galaxies (GRGs) are one of the largest astrophysical sources in the Universe with an overall projected linear size of ~0.7 Mpc or more. Last six decades of radio astron…
