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 New Model for the Milky Way Halo Dispersion Measure with the ENGAWA Simulations: Low DMs and Large Anisotropy

Scott Lucchini, Liam Connor, Samuel McCarty +1

Fast radio burst (FRB) dispersion measures (DMs) are powerful tracers of the low density universe, but interpretation is made difficult by the integrated nature of DM. In this pape…

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…

POLISH'ing the Sky: Wide-Field and High-Dynamic Range Interferometric Image Reconstruction with Application to Strong Lens Discovery

Zihui Wu, Liam Connor, Samuel McCarty +1

Radio interferometry enables high-resolution imaging of astronomical radio sources by synthesizing a large effective aperture from an array of antennas and solving a deconvolution…

The CGM with local universe FRBs: evidence of strong AGN feedback in a massive elliptical galaxy

Samuel McCarty, Liam Connor, Ralf M. Konietzka

Modern cosmology and galaxy formation rely on an understanding of how cosmic baryons are distributed, a significant portion of which exist in the diffuse gas confined to halos. Fas…
