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…

Probing dipole and quadrupole anisotropy in Gamma-ray bursts from Swift dataset

Vedant Mokal, Shantanu Desai

Testing the validity of the cosmological principle's assumption of large-scale isotropy remains crucial for modern cosmology. We investigate the angular distributions of gamma-ray…

A MINOT-based Study of Gamma-ray emission from SPT-CL J2012-5649/Abell 3667

Siddhant Manna, Shantanu Desai

We present an analysis of the non-thermal properties of the merging galaxy cluster SPT-CL J2012-5649/Abell~3667 (, ) using the M…

Study of UV line and continuum variabilities in the Broadline Seyfert 1 Galaxy ESO 141-G55

Mayukh Pahari, Veda Samhita, Harikumar N. +2

We present the results from a 3-year-long Ultraviolet monitoring campaign of the broad line Seyfert 1 galaxy ESO 141-G55 using International Ultraviolet Explorer (IUE). By modellin…

Black hole-Neutron star distinction based on long-term MAXI and Swift study of 42 low mass X-ray binaries

Prakhar Maheshwari, Mayukh Pahari, Anish Sarkar +1

In this study, we analysed about 13 years of publicly available data from MAXI and Swift/BAT to examine the long-term source evolution of 42 transient low-mass X-ray binaries…

Spectro-timing origin of large amplitude X-ray variability in GRS 1915+105 using AstroSat/LAXPC and SXT

Shree Suman, Shuvajit Khatua, Vishal Jadoliya +2

The origin of the large-amplitude, quasi-periodic X-ray flux variations in several classes of the Galactic microquasar GRS~1915+105 remains unresolved. We address this issue throug…

Understanding coronal geometry in NGC 4593 using Fourier frequency-resolved covariance and time-lag spectral analysis

Shree Suman, Mayukh Pahari, Gulab Dewangan +1

Understanding disc-corona geometry through X-ray reverberation variability studies in Seyfert galaxies is crucial, yet our knowledge mostly relies on flux-averaged mean spectral an…
