Analytic Modeling of Synchrotron-Self-Compton Spectra: Application to GRB 190114C
Shotaro Yamasaki, Tsvi Piran
Observations of TeV emission from early gamma-ray burst (GRB) afterglows revealed the long sought for inverse Compton (IC) upscattering of the lower energy synchrotron. However, it…
Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
Bolometric light curves of aspherical shock breakout
Christopher Irwin, Itai Linial, Ehud Nakar +2
The shock breakout emission is the first light that emerges from a supernova. In the spherical case it is characterized by a brief UV flash. In an axisymmetric, non-spherical prola…
What powers the radio emission in TDE AT2019dsg: a long-lived jet or the disruption itself?
Tatsuya Matsumoto, Tsvi Piran, Julian H. Krolik
The tidal disruption event AT2019dsg was observed from radio to X-rays and was possibly accompanied by a high-energy neutrino. Previous interpretations have focused on continued in…
Gravitational Radiation from Accelerating Jets
Elly Leiderschneider, Tsvi Piran
Non-spherical rapid acceleration of mass (or energy) to a relativistic velocity is a natural source of gravitational radiation. Such conditions arise in both long and short gamma-r…
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…
