Determination of neutron star radius from pulse profile modeling using profile likelihood

Vyaas Ramakrishnan, Shantanu Desai

In recent years, NICER data have been extensively used to determine neutron star masses and radii using pulse profile modeling. Pulse profile modeling is implemented with the {\tt…

Search for Lorentz Invariance Violation with spectral lags of GRB 190114C using profile likelihood

Vyaas Ramakrishnan, Shantanu Desai

We search for Lorentz invariance violation (LIV) by re-analyzing the spectral lag data for GRB 190114C from Fermi-GBM using frequentist analysis, where we deal with the astrophysic…

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…
