A Deep Search for Prompt Radio Emission from Thermonuclear Supernovae with the Very Large Array
Laura Chomiuk, Alicia M. Soderberg, Roger A. Chevalier +10
Searches for circumstellar material around Type Ia supernovae (SNe Ia) are one of the most powerful tests of the nature of SN Ia progenitors, and radio observations provide a parti…
Multi-Messenger Tests for Fast-Spinning Newborn Pulsars Embedded in Stripped-Envelope Supernovae
Kazumi Kashiyama, Kohta Murase, Imre Bartos +2
Fast-spinning strongly magnetized newborn neutron stars, including nascent magnetars, are popularly implemented as the engine of luminous stellar explosions. Here, we consider the…
Optical and near-infrared observations of SN 2013dx associated with GRB 130702A
V. L. Toy, S. B. Cenko, J. M. Silverman +33
We present optical and near-infrared light curves and optical spectra of SN 2013dx, associated with the nearby (redshift 0.145) gamma-ray burst GRB 130702A. The prompt isotropic ga…
The Double-Peaked SN2013ge: a Type Ib/c SN with an Asymmetric Mass Ejection or an Extended Progenitor Envelope
M. R. Drout, D. Milisavljevic, J. Parrent +17
We present extensive observations of the Type Ib/c SN2013ge from -13 to +457 days, including spectra and Swift UV-optical photometry beginning 2-4 days post-explosion. This data se…
Hydrodynamic properties of gamma-ray bursts outflows deduced from thermal component
Asaf Pe'er, Hugh Barlow, Shane O'Mahony +5
We study the properties of a significant thermal emission component that was identified in 47 GRBs observed by different instruments. Within the framework of the "fireball" model,…
A common stochastic process rules gamma-ray burst prompt emission and X-ray flares
C. Guidorzi, S. Dichiara, F. Frontera +3
Prompt gamma-ray and early X-ray afterglow emission in gamma-ray bursts (GRBs) are characterized by a bursty behavior and are often interspersed with long quiescent times. There is…
