The Indian Pulsar Timing Array Data Release 2: II. Customised Single-Pulsar Noise Analysis and Noise Budget

K. Nobleson, Churchil Dwivedi, Shantanu Desai +33

We present the results of customised single-pulsar noise analysis of 27 millisecond pulsars from the second data release of the Indian Pulsar Timing Array (InPTA-DR2). We model var…

A test of Amati relation using HII galaxy distances

Rikiya Okazaki, Shantanu Desai

We use model-independent luminosity distances of 186 HII galaxy observations to address the circularity problem in the Amati relation for Gamma-ray Bursts (GRBs). For this purpose,…

Measuring accretion disc properties in the transitional millisecond pulsar PSR J1023+0038 using XMM-Newton, NuSTAR, NICER and Chandra

Vishal Jadoliya, Mayukh Pahari, Sudip Bhattacharyya +1

Whether the accretion disc in the X-ray high-mode of transitional millisecond pulsars (tMSP) reaches near the neutron star surface by penetrating the magnetosphere is a crucial que…

Search for spatial coincidences between galaxy mergers and Fermi-LAT 4FGL-DR4 sources

Siddhant Manna, Shantanu Desai

We present a systematic search for spatial association between a high confidence sample of 3,166 morphologically selected galaxy mergers drawn from the initial convolutional neural…

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…

Post-glitch Recovery and the Neutron Star Structure: The Vela Pulsar

Himanshu Grover, Erbil Gügercinoğlu, Bhal Chandra Joshi +4

We present a detailed analysis of the Vela pulsar's rotational behaviour using approximately 100 months of observational data spanning from September 2016 to January 2025, during w…

Search for spatial coincidence between magnetars and IceCube detected neutrinos

Fathima Shifa M., Shantanu Desai

We implement a search for spatial coincidence between high energy neutrinos detected by the IceCube neutrino detector (using the publicly available 10-year muon track data) and 37…

A Stacked Analysis of GeV Gamma-Ray Emission from SPT-SZ Galaxy Clusters with 16 Years of Fermi-LAT Data

Siddhant Manna, Shantanu Desai

We report a statistically significant detection of cumulative -ray emission from a stacked sample of SPT-SZ selected galaxy clusters using 16.4 years of data from the Fermi Gamm…

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…
