Preferential Occurrence of Fast Radio Bursts in Massive Star-Forming Galaxies
Kritti Sharma, Vikram Ravi, Liam Connor +24
Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond the Milky Way. FRB emission characteristics favor highly magnetized neutron stars, or magnetars, as th…
A Heavily Scattered Fast Radio Burst Is Viewed Through Multiple Galaxy Halos
Jakob T. Faber, Vikram Ravi, Stella Koch Ocker +16
We present a multi-wavelength study of the apparently non-repeating, heavily scattered fast radio burst, FRB 20221219A, detected by the Deep Synoptic Array 110 (DSA-110). The burst…
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…
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…
Deep Synoptic Array Science: First FRB and Host Galaxy Catalog
C. J. Law, K. Sharma, V. Ravi +19
Fast Radio Bursts (FRBs) are a powerful and mysterious new class of transient that are luminous enough to be detected at cosmological distances. By associating FRBs to host galaxie…
