Yet another test of Radial Acceleration Relation for galaxy clusters
S. Pradyumna, Sajal Gupta, Sowmya Seeram +1
We carry out a test of the radial acceleration relation (RAR) for galaxy clusters from two different catalogs compiled in literature, as an independent cross-check of two recent an…
Recent bounds on graviton mass using galaxy clusters
Shantanu Desai, Sajal Gupta
Although galaxy clusters have proved to be wonderful laboratories for testing a plethora of modified gravity theories and other exotic alternatives to CDM, until a few years ago…
Galaxy cluster hydrostatic masses using Tolman-Oppenheimer-Volkoff equation
Sajal Gupta, Shantanu Desai
Motivated by previous studies in literature about the potential importance of relativistic corrections to galaxy cluster hydrostatic masses, we calculate the masses of 12 relaxed c…
Bound on the graviton mass from Chandra X-ray cluster sample
Sajal Gupta, Shantanu Desai
We present new limits on the graviton mass using a sample of 12 relaxed galaxy clusters, for which temperature and gas density profiles were derived by Vikhlinin et al (astro-ph/05…
Limit on graviton mass using stacked galaxy cluster catalogs from SPT-SZ, Planck-SZ and SDSS-redMaPPer
Sajal Gupta, Shantanu Desai
In the last few years, there has been a resurgence of interest in obtaining observational bounds on the graviton mass, following the detection of gravitational waves, because of th…
Magnetar Signature - The U Curve
Vikram Soni, Dipankar Bhattacharya, Sameer Patel +2
This work looks at some definitive signatures of magnetars, in particular of period closures accompanied by a decline of X-ray radiation in two models. We review some of the previo…
