Constraining temperature distribution inside LIGO test masses from frequencies of their vibrational modes
Carl D Blair, Yuri Levin, Eric Thrane
Thermal distortion of test masses, as well as thermal drift of their vibrational mode frequencies, present a major challenge for operation of the Advanced LIGO and Advanced VIRGO i…
Spinning black holes as cosmic string factories
Hengrui Xing, Yuri Levin, Andrei Gruzinov +1
We consider the evolution of a cosmic string loop that is captured by a much more massive and compact black hole. We show that after several reconnections that produce ejections of…
The Thermodynamics of Rotating Black-Hole Star Clusters
Andrei Gruzinov, Yuri Levin, Jiarong Zhu
Rotating star clusters near supermassive black holes are studied using Touma-Tremaine thermodynamics of gravitationally interacting orbital ellipses. A simple numerical procedure f…
Alfvén wave mode conversion in pulsar magnetospheres
Yajie Yuan, Yuri Levin, Ashley Bransgrove +1
The radio emission anomaly coincident with the 2016 glitch of the Vela pulsar may be caused by a star quake that launches Alfvén waves into the magnetosphere, disturbing the origin…
Plasmoid ejection by Alfvén waves and the fast radio bursts from SGR 1935+2154
Yajie Yuan, Andrei M. Beloborodov, Alexander Y. Chen +1
Using numerical simulations we show that low-amplitude Alfvén waves from a magnetar quake propagate to the outer magnetosphere and convert to "plasmoids" (closed magnetic loops) wh…
Precessing flaring magnetar as a source of repeating FRB 180916.J0158+65
Yuri Levin, Andrei M. Beloborodov, Ashley Bransgrove
Recently, CHIME detected periodicity in the bursting rate of the repeating FRB 180916.J0158+65. In a popular class of models, the fast radio bursts (FRBs) are created by giant magn…
