Deterministic and Stochastic Study of the X-ray Emission from the TeV Blazar Mrk~421
Radim Pánis, Gopal Bhatta, Tek P. Adhikari +6
We present a comprehensive timing analysis of X-ray data from the {\it XMM-Newton} satellite, examining 50 light curves covering 17 years of observations of the blazar Mrk~421. Thi…
Constraining Dark Matter Parameters in the Lambda-CDM Framework: A Bayesian Comparison of Planck and DES Constraints
Manjeet Kunwar, Nabin Bhusal, Manil Khatiwada +1
We present a Bayesian analysis of cosmological parameter constraints from early- and late-universe observations, focusing on the matter density parameter () and the amplitude…
Search for High Energy Neutrino Sources using IceCube Neutrino Events and \textit{Fermi}/LAT Observations
Rajendra Neupane, Niraj Dhital
Context. The sources of high-energy astrophysical neutrinos remain largely unknown. Multi-wavelength observational campaignshave identified a few plausible candidates, but their nu…
Probing X-ray Timing and Spectral Variability in the Blazar PKS 2155-304 Over a Decade of XMM-Newton Observations
Gopal Bhatta, Suvas C. Chaudhary, Niraj Dhital +5
Blazars, a class of active galactic nuclei (AGN) powered by supermassive black holes, are known for their remarkable variability across multiple timescales and wavelengths. Despite…
Simulation of the isotropic ultra-high energy photons flux in the solar magnetic field and a comparison with observations made by the HAWC and Fermi-LAT observatories
David Alvarez-Castillo, Piotr Homola, Bożena Poncyljusz +37
In this contribution we study the possibility of the formation of cosmic ray ensembles (CRE) created by the interaction of ultra-high energy (UHE) photons with the magnetic field o…
Constraining X-ray variability of the blazar 3C 273 using XMM-Newton observations over two decades
Adithiya Dinesh, Gopal Bhatta, Tek P. Adhikari +5
Blazars exhibit relentless variability across diverse spatial and temporal frequencies. The study of long- and short-term variability properties observed in the X-ray band provides…
