Role of Future SNIa Data from Rubin LSST in Reinvestigating Cosmological Models
Rahul Shah, Ayan Mitra, Purba Mukherjee +2
We study how future Type-Ia supernovae (SNIa) standard candles detected by the Vera C. Rubin Observatory (LSST) can constrain some cosmological models. We use a realistic three-yea…
Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era
Ayan Mitra, Richard Kessler, Surhud More +2
We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using onl…
Cosmology Requirements on Supernova Photometric Redshift Systematics for Rubin LSST and Roman Space Telescope
Ayan Mitra, Eric V. Linder
Some million Type Ia supernovae (SN) will be discovered and monitored during upcoming wide area time domain surveys such as the Vera C. Rubin Observatory Legacy Survey of Space and…
Cosmology with the Einstein Telescope: No Slip Gravity Model and Redshift Specifications
Ayan Mitra, Jurgen Mifsud, David F. Mota +1
The Einstein Telescope and other third generation interferometric detectors of gravitational waves are projected to be operational post . The cosmological signatures of gravi…
Estimating weak lensing convergence correlation of Type-Ia supernovae from 5-year SNLS data by internal error estimate technique
Ayan Mitra, Arnab Paul, Barun Pal +1
We report non-zero weak lensing convergence correlation signal of Type-Ia supernovae from 5-year Supernovae Legacy Survey data. For our analysis we utilize 296 supernovae magnifica…
Photometric Supernovae Redshift Systematics Requirements
Eric V. Linder, Ayan Mitra
Imaging surveys will find many tens to hundreds of thousands of Type Ia supernovae in the next decade, and measure their light curves. In addition to a need for characterizing thei…
Gravitational Lensing of the supernovae from the Supernova Legacy Survey (SNLS)
Ayan Mitra
The presence of mass inhomogeneities along the line of sight of propagation of light fromdistant objects can induce deflection in the flight path of the photon. This phenomenon is…
Reconstruction of Convergence power spectrum from SNLS weak lensing data
Ayan Mitra, Barun Kumar Pal, Supratik Pal
We estimate the lensing convergence power spectrum from supernovae magnification data using real space correlation function technique. For our analysis we have utilized 296 superno…
