Discovery of a Candidate 2 keV Cyclotron Resonance Scattering Feature in the HLX NGC 3583 X-1
Kiran M. Jayasurya, Aman Upadhyay, Vikram Rana
We present a broadband X-ray study of the transient hyperluminous X-ray source (HLX), 2SXPS J111416.1+481833, in the galaxy NGC 3583, using archival XMM-Newton, NuSTAR, Chandra dat…
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…
