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…
MACS J0553.4-3342: A young merging galaxy cluster caught through the eyes of Chandra and HST
M. B. Pandge, Joydeep Bagchi, S. S. Sonkamble +6
We present a detailed analysis of a young merging galaxy cluster \mac~(z=0.43), from {\it Chandra} X-ray and {\it Hubble Space Telescope} archival data. X-ray observations confirm…
Non-thermal emission and dynamical state of massive galaxy clusters from CLASH sample
M. Pandey-Pommier, J. Richard, F. Combes +5
Massive galaxy clusters are the most violent large scale structures undergoing merger events in the Universe. Based upon their morphological properties in X-rays, they are classifi…
Violent interaction between the AGN and the hot gas in the core of the galaxy cluster Sersic 159-03
N. Werner, M. Sun, J. Bagchi +7
We present a multi-wavelength study of the energetic interaction between the central active galactic nucleus (AGN), the intra-cluster medium, and the optical emission line nebula i…
A diffuse bubble-like radio-halo source MRC 0116+111: imprint of AGN feedback in a low-mass cluster of galaxies
Joydeep Bagchi, Joe Jacob, Gopal-Krishna +4
We present detailed observations of MRC 0116+111, revealing a luminous, mini radio-halo of ~240 kpc diameter located at the centre of a cluster of galaxies at redshift z = 0.131. O…
Diffuse bubble-like radio-halo emission in MRC 0116+111: Imprint of AGN feedback in a distant cluster of galaxies
Joydeep Bagchi, Joe Jacob, Gopal-Krishna +4
We report the discovery of a luminous, mini radio halo of ~240 kpc dimension at the center of a distant cluster of galaxies at redshift z = 0.131. Our optical and multi-wavelength…
