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…
Comparison of symbolic regression algorithms in Star/galaxy/quasar separation
Rachit Deshpande, Shantanu Desai
This work investigates symbolic regression (SR) as an interpretable alternative to black-box machine learning for the classification of stars, galaxies, and quasars in the Sloan Di…
Limit on high energy neutrino emission from Abell 119 using IceCube 10-year muon track data
Sri Devaki Meduri, Shantanu Desai
We carry out a search for high energy muon neutrino emission from the galaxy cluster Abell 119, motivated by a recent detection of GeV gamma rays from this cluster using the Fermi-…
Probing cosmic anisotropy with galaxy clusters and supernovae
Shubham Barua, Sujit K. Dalui, Shantanu Desai
Using CDM and Padé-(2,1) cosmography, we study directional variations in the Hubble constant, , using galaxy cluster and Type Ia Supernovae (from Pantheon Plus) by the he…
Bayesian Model Comparison of versus CDM using HII galaxy Hubble diagram
Yuva Himanshu Pallam, Shantanu Desai
We complement a recent analysis comparing with CDM/CDM using HII galaxies and giant extragalactic HII regions, by carrying out Bayesian model comparison. F…
Search for Gamma-ray emission from Abell 119 galaxy cluster using INTEGRAL/ISGRI, COMPTEL, and DAMPE data
Siddhant Manna, Shantanu Desai
We present a comprehensive search for non-thermal high-energy -ray emission from the nearby merging galaxy cluster Abell~119 () using archival observations spanning ov…
