Radio constraint on outflows from tidal disruption events
Tatsuya Matsumoto, Tsvi Piran
Radio flares from tidal disruption events (TDEs) are generally interpreted as synchrotron emission arising from the interaction of an outflow with the surrounding circumnuclear med…
Limits on mass outflow from optical tidal disruption events
Tatsuya Matsumoto, Tsvi Piran
The discovery of optical/UV tidal disruption events (TDEs) was surprising. The expectation was that, upon returning to the pericenter, the stellar-debris stream will form a compact…
Searching for the radio remnants of short duration gamma-ray bursts
Roberto Ricci, Eleonora Troja, Gabriele Bruni +8
Neutron star mergers produce a substantial amount of fast-moving ejecta, expanding outwardly for years after the merger. The interaction of these ejecta with the surrounding medium…
The origin of hotspots around Sgr A*: Orbital or pattern motion?
Tatsuya Matsumoto, Chi-Ho Chan, Tsvi Piran
The Gravity Collaboration detected a near-infrared hotspot moving around Sgr A* during the 2018 July 22 flare. They fitted the partial loop the hotspot made on the sky with a circu…
Linking extended and plateau emissions of short gamma-ray bursts
Tatsuya Matsumoto, Shigeo S. Kimura, Kohta Murase +1
Some short gamma-ray bursts (SGRBs) show a longer lasting emission phase, called extended emission (EE) lasting , as well as a plateau emission (PE) lasting $…
On short GRBs similar to GRB 170817A detected by Fermi GBM
Tatsuya Matsumoto, Tsvi Piran
von Kienlin et al. (2019) selected 11 short gamma-ray bursts (sGRBs) whose characteristics are similar to GRB 170817A. These bursts, like GRB 170817A, have a hard spike followed by…
