Luminous giants populate the dense Cosmic Web: The radio luminosity-environmental density relation for radio galaxies in action
Martijn S. S. L. Oei, Reinout J. van Weeren, Martin J. Hardcastle +6
Giant radio galaxies (GRGs, giant RGs, or giants) are megaparsec-scale, jet-driven outflows from accretion disks of supermassive black holes, and represent the most extreme pathway…
Identification of Superclusters and their Properties in the Sloan Digital Sky Survey Using WHL Cluster Catalog
Shishir Sankhyayan, Joydeep Bagchi, Elmo Tempel +6
Superclusters are the largest massive structures in the cosmic web on tens to hundreds of megaparsecs (Mpc) scales. They are the largest assembly of galaxy clusters in the Universe…
GMRT unveils steep-spectrum antique filaments in the galaxy cluster Abell 725
M. B. Pandge, Ruta Kale, Pratik Dabhade +2
We present original GMRT radio observations of the galaxy cluster Abell~725, at a redshift of 0.09, along with other archival observations. Our GMRT maps reveal two steep-spectrum…
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…
