Zooming in on the GeV -ray flare of the blazar PKS 1725+123 with a multimessenger lens
Suvas Chandra Chaudhary, Saikat Das, Raj Prince +1
Blazars are promising sources of extragalactic high-energy astrophysical neutrinos, detected at energies TeV by the IceCube neutrino observatory. Here, we report the f…
A newly born spider system at the core of a radio shell: Evidence for a low-energy supernova
S. LazareviÄ, R. Brose, L. M. Oskinova +24
In a search for low surface brightness radio nebulae using the ASKAP-EMU survey, we discovered a faint radio shell, G289.6+5.8, and its central point radio source at the position o…
Photometric and late-time spectropolarimetric observations of GRB 250129A afterglow
A. Ghosh, S. Razzaque, J. Barnard +15
Gamma-Ray Burst (GRB) afterglows arise from the interaction of relativistic ejecta with the circumburst medium and are observed across the electromagnetic spectrum. Afterglow polar…
ZTF Monitoring of ray emitting Narrow Line Seyfert 1 Galaxies
Aman Kumar, Suvas Chandra Chaudhary, Raj Prince +2
The -ray-emitting narrow-line Seyfert-I (-NLSy1) are among the most interesting systems for studying disk-jet coupling. The soft X-ray properties of these systems suggest t…
Unveiling the X-ray Secrets of Fermi-detected Narrow-Line Seyfert 1 Galaxies with XMM-Newton Observations
Suvas Chandra Chaudhary, Raj Prince, Brian van Soelen +1
In the innermost regions of active galactic nuclei, where the accretion disk, corona, and jet processes are closely coupled, X-ray observations offer a direct probe to study the ph…
Exploring Hard X-ray Properties of -ray Emitting Narrow Line Seyfert-I Galaxies through NuSTAR Observations
Suvas Chandra Chaudhary, Raj Prince, Brian van Soelen +1
We studied the six gamma-ray-detected Narrow Line Seyfert 1 (NLSy1) galaxies using the hard X-ray observations from Nuclear Spectroscopic Telescope Array (NuSTAR) and optical g- \&…
