Title:
Radio emission from likely TDEs in galaxies revealed with nuclear mid-IR outbursts

Abstract:
The discovery of transient mid-IR (MIR) emission in centers of galaxies offers 
a unique opportunity to probe the circumnuclear dust and gas, 
and even jet production and evolution, some of which could be resulted from 
the tidal disruption events (TDEs). We will present the our deep JVLA/VLBA/GMRT survey 
of a uniform sample of MIR burst galaxies. The observations reveals 
an unexpected high radio detection rate (~80%) when compared 
with previous radio surveys for optical/UV and X-ray TDEs of similar depth. 
At least 1/5 sources are found with likely transient radio emission, 
which are the most promising candidates that the radio emission is associated with 
the transient accretion due to either a TDE or “turn-on” AGN, 
the latter of which would be novel and interesting phenomenon. 
Our radio observations thus potentially dramatically revise estimates 
of the number of TDEs that produce energetic jets/outflows, 
the nature of which is still poorly understood. 
Our on-going radio observing program will reveal the nature of transient radio emission.
