Quantifying the impact of selection effects on FRB DM- relation cosmological inference

Kritti Sharma, Vikram Ravi, Liam Connor +3

Fast Radio Bursts (FRBs) have emerged as powerful probes of baryonic matter in the Universe, offering constraints on cosmological and feedback parameters through their extragalacti…

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…

Probing baryonic feedback and cosmology with 32-point statistic of FRBs and galaxies

Kritti Sharma, Elisabeth Krause, Vikram Ravi +4

The impact of galaxy formation processes on the matter power spectrum is uncertain and may bias cosmological parameters inferred by large-scale structure surveys. Fast Radio Bursts…

Optical/infrared observations of the extraordinary GRB 250702B: a highly obscured afterglow in a massive galaxy consistent with multiple possible progenitors

Jonathan Carney, Igor Andreoni, Brendan O'Connor +31

GRB 250702B was the longest gamma-ray burst ever detected, with a duration that challenges standard collapsar models and suggests an exotic progenitor. We collected a rich set of o…

Fast Luminous Extragalactic Transients in the VLA Sky Survey: Implications for the rates of Accretion-Induced Collapse Events, Fast Blue Optical Transients and Gamma Ray Burst Afterglows

Kritti Sharma, Vikram Ravi, Dillon Z. Dong +7

Radio wavelengths offer a unique window into high-energy astrophysical phenomena that may be obscured or too rapidly evolving to be captured at other wavelengths. Leveraging data f…

A Correlation Between FRB Dispersion Measure and Foreground Large-Scale Structure

Maryam Hussaini, Liam Connor, Ralf M. Konietzka +4

The distribution of baryons in the Universe remains a fundamental open question in astronomy, and the dispersion measure (DM) of Fast Radio Bursts (FRBs) serves as a valuable tool…

A luminous and hot infrared through X-ray transient at a 5 kpc offset from a dwarf galaxy

Jean J. Somalwar, Vikram Ravi, Raffaella Margutti +20

We are searching for hot, constant-color, offset optical flares in the Zwicky Transient Facility (ZTF) data stream that are from any galaxy in public imaging data from th…

A hydrodynamical simulations-based model that connects the FRB DM--redshift relation to suppression of the matter power spectrum via feedback

Kritti Sharma, Elisabeth Krause, Vikram Ravi +3

Understanding the impact of baryonic feedback on the small-scale (Mpc) matter power spectrum is a key astrophysical challenge, and essential for interpreti…

Evidence for a hot galactic halo around the Andromeda Galaxy using fast radio bursts along two sightlines

Reshma Anna-Thomas, Casey J. Law, Eric W. Koch +17

Fast Radio Bursts (FRBs) are millisecond-duration radio transients that serve as unique probes of ionized extragalactic matter. We report the discovery and localization of two FRBs…
