Understanding constraints on primordial mass black holes made of dark matter using fast radio bursts
Surajit Kalita, Shruti Bhatporia, Amanda Weltman
In recent decades, a multitude of modified gravity theories have been proposed to address a variety of cosmological and astrophysical problems. While many of these theories remain…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Fast Radio Bursts as probes of the late-time universe: a new insight on the Hubble tension
Surajit Kalita, Shruti Bhatporia, Amanda Weltman
Fast Radio Bursts (FRBs) are bright radio transient events, a subset of which have been localized to their host galaxies. Their high dispersion measures offer valuable insights int…
Novel understanding of Cosmological Phenomena using Fast Radio Bursts
Surajit Kalita, Shruti Bhatporia, Amanda Weltman
Fast radio bursts (FRBs) offer unique probes of diverse cosmological phenomena due to their characteristic properties, including short duration timescale and high dispersion measur…
A Topological Data Analysis of the CHIME/FRB Catalogues
Shruti Bhatporia, Anthony Walters, Jeff Murugan +1
In this paper, we use Topological Data Analysis (TDA), a mathematical approach for studying data shape, to analyse Fast Radio Bursts (FRBs). Applying the Mapper algorithm, we visua…
Gravitational Lensing in Modified Gravity: A case study for Fast Radio Bursts
Surajit Kalita, Shruti Bhatporia, Amanda Weltman
Over the last few decades, a plethora of modifications to general relativity have been proposed to solve a host of cosmological and astrophysical problems. Many modified gravity mo…
The Hydrogen Intensity and Real-time Analysis eXperiment: 256-Element Array Status and Overview
Devin Crichton, Moumita Aich, Adam Amara +97
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the S…
Implementing and Characterizing Real-time Broadband RFI Excision for the GMRT Wideband Backend
Kaushal D. Buch, Kishor Naik, Swapnil Nalawade +3
The Giant Metrewave Radio Telescope (GMRT) is being upgraded to increase the receiver sensitivity. This makes the receiver more susceptible to man-made Radio Frequency Interference…
