Tracing the Host-Galaxy Environments of FRBs with a New Sample of Localized Sources Detected with the DSA-110
Frank M. Verdi, Vikram Ravi, Myles B. Sherman +7
We characterize the source environments of a sample of fast radio bursts (FRBs) detected with the Deep Synoptic Array (DSA-110). We present new analyses of a sample of 24 FRBs whic…
The DSA/Chronoscope fast radio burst survey: forecasts and science overview
Liam Connor, Kaitlyn Shin, Vikram Ravi +14
Fast radio bursts (FRBs) are bright extragalactic transients with several mysteries surrounding their origins. Large FRB samples enable accurate measurements of the cosmic matter d…
VLASS Discovery of a Luminous Galactic Radio Transient Evolving on Decade Timescales
Jessie M. Miller, Gregg Hallinan, Dillon Dong +10
We present a multiwavelength analysis of the radio transient VT J1906+0849, discovered as a 70 mJy source in Epoch 1 of the Very Large Array Sky Survey (VLASS), 21 yr after an NRAO…
A new measurement of the FRB DM-galaxy cross correlation and a first joint analysis with the kinematic SZ effect
Samuel McCarty, Liam Connor, Kritti Sharma +8
Understanding the distribution of cosmic baryons is crucial for advancing cosmology and galaxy formation. Localized Fast Radio Bursts (FRBs) are a promising new probe of the diffus…
A spectacular multi-wavelength transient associated with an off-axis relativistic jet
Delina Levine, Gregg Hallinan, Jean J. Somalwar +10
Many of the most luminous extragalactic transients originate from the accretion of material onto a black hole (BH) via core-collapse, stellar mergers, or the tidal disruption of a…
The Radio-FIR Correlation in the Context of Deep Radio Source Counts
Tirth D. Surti, Vikram Ravi, Allison Matthews +1
Increasingly deep, confusion-limited radio surveys have pushed direct radio source-count measurements down to tens of Jy at 1.4 GHz. Confusion-noise P(D) analyses extend the sta…
A Decade to Map the Diffuse Universe: FRB-QSO Pairs with HST/COS Spectroscopy
Jessica Werk, Matthew McQuinn, J. Xavier Prochaska +16
Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints o…
Detecting the Axion-Photon Conversion Background
Felix Weber, Vikram Ravi
The potential to detect axion dark matter through astrophysical processes has shown high promise in recent years. We therefore expand on previous work studying the axion-to-photon…
Baryons in the Darkest Sites of the Universe
Kritti Sharma, Vikram Ravi, Dhayaa Anbajagane +9
The pristine underdense patches of the Universe, cosmic voids, are powerful cosmological laboratories, uniquely sensitive to dark energy, modified gravity, and neutrino masses, yet…
Backlighting the Cosmic Web with Fast Radio Bursts: An Anthology of Dispersion Measure Cross-Correlations with Large-Scale Structure and Baryon Tracers
Kritti Sharma, Elisabeth Krause, Vikram Ravi +11
Fast Radio Bursts (FRBs) probe baryons permeating the cosmic web through their dispersion measures (DMs), which encode the integrated electron density along cosmological sightlines…
Signatures of Suppressed Matter Clustering revealed by Fast Radio Bursts
Kritti Sharma, Elisabeth Krause, Vikram Ravi +3
Complex astrophysical processes regulate the growth of galaxies by injecting energy and momentum into their surroundings, redistributing baryons across megaparsec scales. The clust…
Great Walls of Cosmic Baryons in the Northern Sky
Vikram Ravi, Kritti Sharma, Liam Connor
The dispersion measures (DMs) of fast radio bursts (FRBs) encode the total ionized-gas column densities along their sightlines. Most observed FRBs originate at distances where the…
