Determination of Hubble constant from Megamaser Cosmology Project using Profile Likelihood
Shubham Barua, Vyaas Ramakrishnan, Shantanu Desai
The Megamaser Cosmology Project inferred a value for the Hubble constant given by km/sec/Mpc. This value was obtained using Bayesian inference by marginalizing…

Constraints on Lorentz Invariance Violation from Gamma-ray Burst rest-frame spectral lags using Profile Likelihood
Vyaas Ramakrishnan, Shantanu Desai
We reanalyze the spectral lag data for 56 Gamma-Ray Bursts (GRBs) in the cosmological rest frame to search for Lorentz Invariance Violation (LIV) using frequentist inference. For t…

Search for transient gamma-ray emission from magnetar flares using Fermi-LAT
Vyaas Ramakrishnan, Shantanu Desai
We search for transient gamma-ray emission in the energy range from 0.1-10 GeV using data from the Fermi-LAT telescope in coincidence with magnetar flares. For our analysis, we loo…
