Detecting Population III Stars through Tidal Disruption Events in the Era of JWST and Roman
Rudrani Kar Chowdhury, Janet N. Y. Chang, Lixin Dai +1
The first generation metal-free stars, referred to as population III (Pop III) stars, are believed to be the first objects to form out of the pristine gas in the very early Univers…
The radio detection and accretion properties of the peculiar nuclear transient AT 2019avd
Yanan Wang, Ranieri D. Baldi, Santiago del Palacio +19
AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and…
Linear and circular polarimetry of the optically bright relativistic Tidal Disruption Event AT 2022cmc
Aleksandar Cikota, Giorgos Leloudas, Mattia Bulla +3
Tidal disruption events (TDEs) occur when a star orbiting a massive black hole is sufficiently close to be tidally ripped apart by the black hole. AT 2022cmc is the first relativis…
The Effects of Gas Angular Momentum on the Formation of Magnetically Arrested Disks and the Launching of Powerful Jets
Tom M. Kwan, Lixin Dai, Alexander Tchekhovskoy
In this letter, we investigate Bondi-like accretion flows with zero or low specific angular momentum by performing 3D general relativistic magnetohydrodynamic simulations. In order…
The properties of wind and jet from a super-Eddington accretion flow around a supermassive black hole
Hai Yang, Feng Yuan, Tom Kwan +1
Wind and jet are important medium of AGN feedback thus it is crucial to obtain their properties for the feedback study. In this paper we investigate the properties of wind and jet…
An asymmetric electron-scattering photosphere around optical tidal disruption events
Giorgos Leloudas, Mattia Bulla, Aleksandar Cikota +10
A star crossing the tidal radius of a supermassive black hole will be spectacularly ripped apart with an accompanying burst of radiation. A few tens of such tidal disruption events…
