Constraints on GRB Jet Properties from IceCube Upper Limits: Insights from GRB 221009A and GRB 240825A
Chiranjeet Pradhan, Khushboo Sharma, Abhijit Roy +1
The IceCube neutrino telescope has provided upper limits on neutrino emission from gamma ray bursts. These constraints provided by the IceCube detector have been instrumental in in…
Hadronic Emissions from the Microquasar V4641 Sgr, SS433, and its implications in the Diffuse Galactic Emission
Basanti Paul, Abhijit Roy, Jagdish C. Joshi +1
Microquasars (MQs) are Galactic binary systems, consisting of a star and a compact object, a neutron star or a stellar mass black hole, which accretes matter from its companion sta…
Multi Messenger Study of GRB 221009A with VHE Gamma-ray and Neutrino Afterglow from a Gaussian Structured Jet
T. Mondal, S. Razzaque, Jagdish C. Joshi +2
Recent detections of very-high-energy (VHE; ) emission from GRB afterglows, most notably the unprecedented brightness of GRB~221009A observed by LHAASO, reve…
Hadronuclear interactions in AGN jets as the origin of the diffuse high-energy neutrino background
Rui Xue, Ze-Rui Wang, Jagdish C. Joshi +1
The origin of diffuse high-energy neutrinos from TeV to PeV energies detected by IceCube Observatory remains a mystery. In our previous work, we have shown that hadronuclear (p-p)…
