The observed phase space of mass-loss history from massive stars based on radio observations of a large supernova sample

Itai Sfaradi, Assaf Horesh, Rob Fender +4

In this work we study the circumstellar material (CSM) around massive stars, and the mass-loss rates depositing this CSM, using a large sample of radio observations of 325 core-col…

Late-Time Supernovae Radio Re-brightening in the VAST Pilot Survey

Kovi Rose, Assaf Horesh, Tara Murphy +12

We present our analysis of supernovae serendipitously found to be radio-bright several years after their optical discovery. We used recent observations from the Australian SKA Path…

The Birth of a Relativistic Jet Following the Disruption of a Star by a Cosmological Black Hole

Dheeraj R. Pasham, Matteo Lucchini, Tanmoy Laskar +63

A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boos…

Are Delayed Radio Flares Common in Tidal Disruption Events? The Case of the TDE iPTF16fnl

Assaf Horesh, Itai Sfaradi, Rob Fender +3

Radio emission from tidal disruption events (TDEs) originates from an interaction of an outflow with the super-massive black hole (SMBH) circum nuclear material (CNM). In turn, thi…

Two stripped envelope supernovae with circumstellar interaction -- but only one really shows it

J. Sollerman, C. Fransson, C. Barbarino +23

We present SN 2019tsf (ZTF19ackjszs) and SN 2019oys (ZTF19abucwzt). These two stripped envelope Type Ib supernovae suddenly showed a (re-)brightening in their late light curves. We…

A non-equipartition shockwave traveling in a dense circumstellar environment around SN2020oi

Assaf Horesh, Itai Sfaradi, Mattias Ergon +34

We report the discovery and panchromatic followup observations of the young Type Ic supernova, SN2020oi, in M100, a grand design spiral galaxy at a mere distance of Mpc. We fo…
