Determination of neutron star radius from pulse profile modeling using profile likelihood
Vyaas Ramakrishnan, Shantanu Desai
The paper demonstrates a frequentist profile‑likelihood method for extracting neutron star radii from NICER pulse‑profile data, showing comparable precision to Bayesian approaches…
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…
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…
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…
