Supernova 2020wnt: An Atypical Superluminous Supernova with a Hidden Central Engine
Samaporn Tinyanont, Stan E. Woosley, Kirsty Taggart +34
We present observations of a peculiar hydrogen- and helium-poor stripped-envelope (SE) supernova (SN) 2020wnt, primarily in the optical and near-infrared (near-IR). Its peak absolu…
A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Deep Synoptic Array science I: discovery of the host galaxy of FRB 20220912A
Vikram Ravi, Morgan Catha, Ge Chen +25
We report the detection and interferometric localization of the repeating fast radio burst (FRB) source FRB 20220912A during commissioning observations with the Deep Synoptic Array…
A candidate relativistic tidal disruption event at 340 Mpc
Jean J. Somalwar, Vikram Ravi, Dillon Z. Dong +13
We present observations of an extreme radio flare, VT J024345.70-284040.08, hereafter VT J0243, from the nucleus of a galaxy with evidence for historic Seyfert activity at redshift…
Stellar prospects for FRB gravitational lensing
Liam Connor, Vikram Ravi
Gravitational lensing of fast radio bursts (FRBs) offers an exciting avenue for several cosmological applications. However, it is not yet clear how many such events future surveys…
Models of Millimeter and Radio Emission from Interacting Supernovae
Nitika Yadlapalli, Vikram Ravi, Anna Y. Q. Ho
This work utilizes established models of synchrotron-powered light curves for core-collapse supernovae in dense circumstellar environments, namely type IIn and Ibn, to demonstrate…
The Tidal Disruption Event AT2021ehb: Evidence of Relativistic Disk Reflection, and Rapid Evolution of the Disk-Corona System
Yuhan Yao, Wenbin Lu, Muryel Guolo +29
We present X-ray, UV, optical, and radio observations of the nearby ( Mpc) tidal disruption event (TDE) AT2021ehb/ZTF21aanxhjv during its first 430 days of evolution. AT…
New Tests of Millilensing in the Blazar PKS 1413+135
A. L. Peirson, I. Liodakis, A. C. S. Readhead +26
Symmetric Achromatic Variability (SAV) is a rare form of radio variability in blazars that has been attributed to gravitational millilensing by a ~ mass cond…
A comprehensive observational study of the FRB 121102 persistent radio source
Ge Chen, Vikram Ravi, Gregg W. Hallinan
FRB 121102 is the first fast radio burst source to be spatially associated with a persistent radio source (QRS121102), the nature of which remains unknown. We present a detailed ob…
