Nandita Khetan (Gran Sasso Science Institute) “Cosmology in the multi-messenger era”

January 14 @ 4:00 pm - 5:00 pm

The talk will present my PhD project research which focuses on advancing the standardization of various transients to be used as cosmological probes and the evaluation of the Hubble constant (H0). With SN Ia, I will present interesting results coming from a recent work where I used an alternate way to calibrate SN Ia based on the surface brightness fluctuations (SBF) method. Besides SNe Ia, I explored other exotic/new transients like Superluminous supernovae, Kilonovae and Gravitational waves as distance indicators. In particular, I worked on SLSNe in rest frame UV wavelengths to find peak luminosity correlations with light curve properties. I participated in a project exploring KNe as a standard candle to perform independent measurements of H0. I am currently working on the prospects of calibrating SNe Ia with GW distances measured from future GW detectors. I will briefly present these cosmological probes and discuss their future perspectives.
