Constraints on Off-axis Grb Jets in Type Ibc Supernovae from Late-time Radio Observations
It has been suggested that the peculiar properties of the luminous Type Ic supernova SN 1998bw and its lowenergy gamma-ray burst GRB 980425 may be understood if they originated in a standard gamma-ray burst explosion viewed far from the axis of the relativistic jet. In this scenario, strong radio emission is predicted from the jet on a timescale 1 to 10 years after the explosion as it decelerat...

متن کاملSRG/eROSITA prospects for the detection of stellar tidal disruption flares
We discuss the potential of the eROSITA telescope on board the Spectrum-RoentgenGamma (SRG) observatory to detect stellar tidal disruption events (TDE) during its 4-year all-sky survey. We propose to distinguish such events from other X-ray transients using two criteria: i) large (more than a factor of 10) X-ray variation between two subsequent 6-month scans of the sky and ii) soft X-ray spectr...
متن کاملA radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li.
The tidal disruption of a star by a supermassive black hole leads to a short-lived thermal flare. Despite extensive searches, radio follow-up observations of known thermal stellar tidal disruption flares (TDFs) have not yet produced a conclusive detection. We present a detection of variable radio emission from a thermal TDF, which we interpret as originating from a newly launched jet. The multi...
متن کاملLate-time Radio Observations of 74 Type Ibc Supernovae: Strong Constraints on Off-axis Gamma-ray Bursts
We present late-time radio observations of 74 local Type Ibc supernovae, including six events with broad optical absorption lines (“hypernovae”). None of these objects show evidence for radio emission attributable to offaxis gamma-ray burst jets spreading into our line-of-sight. Comparison with our afterglow models reveals the following conclusions: (1) Less than ∼ 1.4% of Type Ibc supernovae a...
