Radiative cooling in collisionally and photo ionized plasmas
M. L. Lykins, G. J. Ferland, Ryan L. Porter +3
We discuss recent improvements in the calculation of the radiative cooling in both collisionally and photo ionized plasmas. We are extending the spectral simulation code Cloudy so…
Radio Monitoring of the Tidal Disruption Event Swift J164449.3+573451. II. The Relativistic Jet Shuts Off and a Transition to Forward Shock X-ray/Radio Emission
B. A. Zauderer, E. Berger, R. Margutti +5
We present continued multi-frequency radio observations of the relativistic tidal disruption event Sw1644+57 extending to dt~600 d. The data were obtained with the JVLA and AMI Lar…
Jet Luminosity From Neutrino-Dominated Accretion Flows in Gamma-Ray Bursts
Norita Kawanaka, Tsvi Piran, Julian H. Krolik
A hyperaccretion disk formed around a stellar mass black hole is a plausible model for the central engine that powers gamma-ray bursts (GRBs). If the central black hole rotates and…
Time Scales in Tidal Disruption Events
Tsvi Piran, Julian Krolik
We explore the temporal structure of tidal disruption events pointing out the corresponding transitions in the lightcurves of the thermal accretion disk and of the jet emerging fro…
Maximum synchrotron frequency for shock-accelerated particles
P. Kumar, R. A. Hernández, Z. Bosnjak +1
It is widely believed that the maximum energy of synchrotron photons when electrons are accelerated in shocks via the Fermi process is about 50 MeV (in plasma comoving frame). We s…
Consequences of Strong Compression in Tidal Disruption Events
Nicholas Stone, Re'em Sari, Abraham Loeb
The tidal disruption of a star by a supermassive black hole (SMBH) is a highly energetic event with consequences dependent on the degree to which the star plunges inside the SMBH's…
