Building the peanut: simulations and observations of peanut-shaped structures and ansae in face-on disk galaxies
Kanak Saha, Alister W. Graham, Isabel Rodríguez-Herranz
(X/peanut)-shaped features observed in a significant fraction of disk galaxies are thought to have formed from vertically buckled bars. Despite being three dimensional structures,…
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…
Discovery of a new, 2.2 Mpc Giant Radio Galaxy at a redshift of 0.57
Biny Sebastian, C. H. Ishwara-Chandra, Ravi Joshi +1
We report the discovery of one of the largest and most distant Giant Radio Galaxy (GRG) in the Lynx field which was discovered using deep Giant Metre-wave Radio Telescope (GMRT) 15…
On the incidence of MgII absorbers along the blazar sightlines
S. Mishra, H. Chand, Gopal-Krishna +3
It is widely believed that the cool gas clouds traced by MgII absorption, within a velocity offset of 5000 km/s relative to the background quasar are mostly associated with the qua…
A Giant Metrewave Radio Telescope search for associated H{\sc i} 21\,cm absorption in GHz-peaked-spectrum sources
J. N. H. S. Aditya, Nissim Kanekar
We report the first detections of associated H{\sc i} 21\,cm absorption in Gigahertz-peaked-spectrum (GPS) sources at high redshifts, , using the Giant Metrewave Radio Teles…
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…
