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…
SN 2023uqf: An Interacting Supernova Coincident with a High-Energy Neutrino
Robert Stein, Anna Y. Q. Ho, Anjasha Gangopadhyay +30
Astrophysical high-energy (TeV-PeV) neutrinos were first discovered in 2013, but their origin remains largely unknown. Here we present SN 2023uqf, a supernova found in coincidence…
Ray-tracing Fast Radio Bursts Through IllustrisTNG: Cosmological Dispersion Measures from Redshift 0 to 5.5
Ralf M. Konietzka, Liam Connor, Vadim A. Semenov +3
The dispersion measures (DMs) of Fast Radio Bursts (FRBs) arise predominantly from free electrons in the large-scale structure of the Universe. The increasing number of FRB observa…
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…
GReX: An Instrument Overview and New Upper Limits on the Galactic FRB Population
K. A. Shila, S. Niedbalski, L. Connor +14
We present the instrument design and initial results for the Galactic Radio Explorer (GReX), an all-sky monitor for exceptionally bright transients in the radio sky. This instrumen…
Physics beyond the Standard Model with the DSA-2000
Kim V. Berghaus, Yufeng Du, Vincent S. H. Lee +4
The upcoming Deep Synoptic Array 2000 (DSA-2000) will map the radio sky at GHz (eV) with unprecedented sensitivity. This will enable searches for dark matte…
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…
Discovery of two new polars evolved past the period bounce
Tim Cunningham, Ilaria Caiazzo, Gracjan Sienkiewicz +13
We report the discovery of two new magnetic cataclysmic variables with brown dwarf companions and long orbital periods ( and min). This discovery incr…
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…
