VLASS tidal disruption events with optical flares II: discovery of two TDEs with intermediate width Balmer emission lines and connections to the ambiguous extreme coronal line emitters
Jean J. Somalwar, Vikram Ravi, Wenbin Lu
The multiwavelength properties of radio-emitting tidal disruption events (TDEs) are poorly understood. In a previous paper, we presented the first sample of radio-selected, optical…
VLASS tidal disruption events with optical flares I: the sample and a comparison to optically-selected TDEs
Jean J. Somalwar, Vikram Ravi, Dillon Z. Dong +11
In this work, we use the Jansky VLA Sky Survey (VLASS) to compile the first sample of six radio-selected tidal disruption events (TDEs) with transient optical counterparts. While w…
The first systematically identified repeating partial tidal disruption event
Jean J. Somalwar, Vikram Ravi, Yuhan Yao +13
Tidal disruption events (TDEs) occur when a star enters the tidal radius of a supermassive black hole (SMBH). If the star only grazes the tidal radius, a fraction of the stellar ma…
Deep Synoptic Array Science: Implications of Faraday Rotation Measures of Localized Fast Radio Bursts
Myles B. Sherman, Liam Connor, Vikram Ravi +20
Faraday rotation measures (RMs) of fast radio bursts (FRBs) offer the prospect of directly measuring extragalactic magnetic fields. We present an analysis of the RMs of ten as yet…
Deep Synoptic Array Science: Polarimetry of 25 New Fast Radio Bursts Provides Insights into their Origins
Myles B. Sherman, Liam Connor, Vikram Ravi +20
We report on a full-polarization analysis of the first 25 as yet non-repeating FRBs detected at 1.4 GHz by the 110-antenna Deep Synoptic Array (DSA-110) during commissioning observ…
The origin of the nano-Hertz stochastic gravitational wave background: the contribution from supermassive black-hole binaries
Jean J. Somalwar, Vikram Ravi
The nano-Hertz gravitational wave background (GWB) is a key probe of supermassive black hole (SMBH) formation and evolution, if the background arises predominantly from binary SMBH…
