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 "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…

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…

Constraining the FRB mechanism from scintillation in the host galaxy

Pawan Kumar, Paz Beniamini, Om Gupta +1

Most FRB models can be divided into two groups based on the distance of the radio emission region from the central engine. The first group of models, the so-called `nearby' or magn…

Pulsar revival in neutron star mergers: multi-messenger prospects for the discovery of pre-merger coherent radio emission

A. J. Cooper, O. Gupta, Z. Wadiasingh +5

We investigate pre-merger coherent radio emission from neutron star mergers arising due to the magnetospheric interaction between compact objects. We consider two plausible radiati…

A Comparative Analysis of Machine-learning Models for Solar Flare Forecasting: Identifying High-performing Active Region Flare Indicators

Suvadip Sinha, Om Gupta, Vishal Singh +9

Solar flares create adverse space weather impacting space and Earth-based technologies. However, the difficulty of forecasting flares, and by extension severe space weather, is acc…
