The physical properties of fast radio burst (FRB) host galaxies provide important clues towards the nature of FRB sources. The 16 FRB hosts identified thus far span three orders of…
ALMA and NOEMA constraints on synchrotron nebular emission from embryonic superluminous supernova remnants and radio-gamma-ray connection
Kohta Murase, Conor M. B. Omand, Deanne L. Coppejans +8
Fast-rotating pulsars and magnetars have been suggested as the central engines of super-luminous supernovae (SLSNe) and fast radio bursts, and this scenario naturally predicts non-…

Vikram Ravi, Hannah Dykaar, Jackson Codd +6
We present the discovery of the fading radio transient FIRST J153350.8+272729. The source had a maximum observed 5-GHz radio luminosity of erg s in 1986, bu…
A Distant Fast Radio Burst Associated to its Host Galaxy with the Very Large Array

We present the discovery and subarcsecond localization of a new Fast Radio Burst with the Karl G. Jansky Very Large Array and realfast search system. The FRB was discovered on 2019…
VLA/Realfast Detection of a Burst from FRB180916.J0158+65 and Tests for Periodic Activity
Kshitij Aggarwal, Casey J. Law, Sarah Burke-Spolaor +5
We report on the detection of a burst from FRB180916 by realfast/VLA and present software for interpreting fast radio bursts (FRB) periodicity. We demonstrate a range of periodicit…
A Demonstration of Extremely Low Latency -ray, X-Ray & UV Follow-Up of a Millisecond Radio Transient
Aaron Tohuvavohu, Casey J. Law, Jamie A. Kennea +18
We report results of a novel high-energy follow-up observation of a potential Fast Radio Burst. The radio burst was detected by VLA/realfast and followed-up by the Neil Gehrels Swi…

We present results of a search for late-time radio emission and Fast Radio Bursts (FRBs) from a sample of type-I superluminous supernovae (SLSNe-I). We used the Karl G. Jansky Very…
Fast Radio Burst Tomography of the Unseen Universe
Vikram Ravi, Nicholas Battaglia, Sarah Burke-Spolaor +13
The discovery of Fast Radio Bursts (FRBs) at cosmological distances has opened a powerful window on otherwise unseen matter in the Universe. In the 2020s, observations of …
