High-Resolution Numerical Calculations of GRB Afterglow Plateaus arising from Stratified Ejecta
Paul C. Duffell, Ranadeep Ghosh Dastidar
The paper presents high‑resolution relativistic hydrodynamic simulations showing that a stratified ejecta structure can naturally produce the plateau phase observed in gamma‑ray bu…
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…
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…
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…
