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…
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…
Deep Synoptic Array Science: Searching for Long Duration Radio Transients with the DSA-110
Myles B. Sherman, Nikita Kosogorov, Casey Law +10
We describe the design and commissioning tests for the DSA-110 Not-So-Fast Radio Burst (NSFRB) search pipeline, a 1.4GHz image-plane single-pulse search sensitive to 134ms-160.8s r…
