AT2018hyz: Predictions for a Sky Projection from a Delayed Off-Axis Jet
Ranadeep Ghosh Dastidar, Paul C Duffell
Initially discovered optically, Tidal Disruption Event (TDE) AT2018hyz was first detected in radio 972 days later. The continued monitoring of the event revealed a late-time (1370-…
High-Resolution Numerical Calculations of GRB Afterglow Plateaus arising from Stratified Ejecta
Paul C. Duffell, Ranadeep Ghosh Dastidar
Since the discovery of plateaus in GRB afterglows by Swift, they have been modeled predominantly by late-time energy injection. However, many studies have suggested that the platea…
A Late-time Radio Search for Highly Off-axis Jets from PTF Broad-lined Ic Supernovae in GRB-like Host Galaxy Environments
Genevieve Schroeder, Anna Y. Q. Ho, Ranadeep G. Dastidar +3
Hydrogen/Helium-poor stripped-envelope core-collapse supernovae with broad lines (SNe Ic-bl) almost always accompany the nearby () jetted relativistic explosions known as…
A Novel Relationship Between Gamma Ray Burst Duration And Photospheric Radius
Ranadeep Ghosh Dastidar, Paul Duffell
Long Gamma Ray Bursts (lGRBs) are associated with jets in Type Ic broadline supernovae. The Collapsar model provides a theoretical framework for the jet formation from the core col…
EP250108a/SN 2025kg: A Jet-Driven Stellar Explosion Interacting With Circumstellar Material
Gokul P. Srinivasaragavan, Hamid Hamidani, Genevieve Schroeder +28
We present optical, radio, and X-ray observations of EP250108a/SN 2025kg, a broad-line Type Ic supernova (SN Ic-BL) accompanying an Einstein Probe (EP) fast X-ray transient (FXT) a…
Could the recent rebrightening of the GW170817A afterglow be caused by a counter jet?
Ranadeep Ghosh Dastidar, Paul Duffell
GRB170817A (also GW170817) became the first binary neutron star (BNS) merger event detected via gravitational waves and electromagnetic signals. Over the next 4 years, various mult…
jetsimpy: A Highly Efficient Hydrodynamic Code for Gamma-ray Burst Afterglow
Hao Wang, Ranadeep G. Dastidar, Dimitrios Giannios +1
Gamma-ray burst (GRB) afterglows are emissions from ultrarelativistic blast waves produced by a narrow jet interacting with surrounding matter. Since the first multimessenger obser…
