Evidence for Enhancement in the Rate of Fast Radio Bursts Toward Galaxy Clusters
Mawson W. Sammons, Airene Ahuja, Matt Dobbs +25
Massive galaxy clusters can introduce gravitational lensing and populations of suppressed star formation member galaxies into the line of sight, potentially changing the distributi…
Fast Radio Bursts probe Galaxy Evolution: Evidence and implications of a redshift-dependent FRB host DM
Lluis Mas-Ribas
The redshift evolution of ionized gas in the full galaxy-halo system is a central open question in galaxy formation, because no existing observable is simultaneously sensitive to a…
Constraining Gas Mass Fractions in Galaxy Groups and Clusters with the First CHIME/FRB Outrigger
Adam E. Lanman, Sunil Simha, Kiyoshi W. Masui +16
In recent years, localized fast radio bursts (FRBs) have emerged as a powerful tool to study the structure of the baryonic matter in the universe. Their dispersion measures (DMs) s…
Constraining the mass of the M31 ionized baryon Halo using CHIME/FRB Catalog 2
Lordrick A. Kahinga, J. Xavier Prochaska, Sunil Simha +21
The circumgalactic medium (CGM) surrounding galaxies is believed to be a significant reservoir of baryons, yet its total mass remains poorly constrained. We present a novel approac…
A DM relation for FRB hosts?
Lluis Mas-Ribas, Clancy W. James
It has been proposed that measurements of scattering times () from fast radio bursts (FRB) may be used to infer the FRB host dispersion measure (DM) and its redshift. This appr…
Repeating versus Nonrepeating Fast Radio Bursts: A Deep Learning Approach to Morphological Characterization
Bikash Kharel, Emmanuel Fonseca, Charanjot Brar +6
We present a deep learning approach to classify fast radio bursts (FRBs) based purely on morphology as encoded on recorded dynamic spectrum from CHIME/FRB Catalog 2. We implemented…
