Constraining the near-source relativistic wind medium using Fast Radio Burst circular polarization data
Om Gupta, Pawan Kumar, Paz Beniamini
Fast Radio Bursts (FRBs) exhibit diverse spectro-temporal characteristics, which can probe vital propagation and source physics via Stokes polarimetry. We investigate whether the c…
The Role of Scintillation in Detecting HI Absorption in FRB Spectra
Om Gupta, Pawan Kumar, Paz Beniamini +1
The 21-cm absorption line of neutral hydrogen has been a long hypothesized observational feature of the spectra of Fast Radio Bursts (FRBs). The difficulties associated with detect…
The Cosmic Evolution of Fast Radio Bursts Inferred from the CHIME/FRB Baseband Catalog 1
Om Gupta, Paz Beniamini, Pawan Kumar +1
Redshift and luminosity distributions are essential for understanding the cosmic evolution of extragalactic objects and phenomena, such as galaxies, gamma-ray bursts, and fast radi…
The "Dark-Matter Dominated" Galaxy Segue 1 Modeled with a Black Hole and no Dark Halo
Nathaniel Lujan, Karl Gebhardt, Richard Anantua +11
The dwarf spheroidal galaxy, Segue 1, is thought to have one of the largest ratios of dark matter to stellar mass. Using orbit-based dynamical models, we model Segue 1, including a…
