The shape distribution of superclusters in SDSS DR 12
Satadru Bag, Lauri Juhan Liivamägi, Maret Einasto
Galaxy superclusters, the largest galaxy structures in the cosmic web, are formed due to the gravitational collapse (although they are not usually gravitationally bound). Their geo…
Identifying lensed quasars and measuring their time-delays from unresolved light curves
Satadru Bag, Arman Shafieloo, Kai Liao +1
Identifying multiply imaged quasars is challenging due to their low density in the sky and the limited angular resolution of wide field surveys. We show that multiply imaged quasar…
A novel approach for calculating galaxy rotation curves using spaxel cross-correlation and iterative smoothing
Satadru Bag, Arman Shafieloo, Rory Smith +5
Precise measurements of the internal dynamics of galaxies have proven of great importance for understanding the internal dark matter distribution of galaxies. We present a novel me…
Out of One, Many: Distinguishing Time Delays from Lensed Supernovae
Mikhail Denissenya, Satadru Bag, Alex G. Kim +2
Gravitationally lensed Type Ia supernovae are an emerging probe with great potential for constraining dark energy, spatial curvature, and the Hubble constant. The multiple images a…
Phantom braneworld and the Hubble tension
Satadru Bag, Varun Sahni, Arman Shafieloo +1
Braneworld models with induced gravity exhibit phantom-like behaviour of the effective equation of state of dark energy. They can, therefore, naturally accommodate higher values of…
