Survey of compact sources for pulsars and exotic objects -- I. Overview and initial discoveries
Yogesh Maan, Apurba Bera, Dharam Vir Lal +4
Targeted searches for pulsars based on their counterparts in radio images have resulted in the discovery of interesting pulsars including the first ever discovered millisecond puls…
Detecting HI Absorption in FRB Spectra: Modern Prospects and Scientific Utility
Hugh Roxburgh, Marcin Glowacki, Apurba Bera +1
Fast radio bursts (FRBs) emit broadband radio emission that may, in rare cases, encode atomic hydrogen (HI) absorption signals as they traverse the interstellar medium of their hos…
The Low-mass Dwarf Host Galaxy of Nonrepeating FRB 20230708A
August R. Muller, Alexa C. Gordon, Stuart D. Ryder +19
We present Very Large Telescope/X-Shooter spectroscopy for the host galaxies of 12 fast radio bursts (FRBs) detected by the Australian SKA Pathfinder observed through the ``Fast an…
Constraining FRB Microstructure with Polarised Shot Noise
J. C. F. Balzan, A. Bera, C. W. James +1
We present FIRES, a polarised shot-noise (PSN) framework that models fast radio burst (FRB) dynamic spectra as the incoherent superposition of Gaussian microshots with varying pola…
From NVSS to RACS: Identifying truly Compact and Steep spectrum Radio sources
Rajat Shinde, Yogesh Maan, Apurba Bera
Compact, steep-spectrum radio sources are key tracers of exotic astrophysical objects such as pulsars and high-redshift radio galaxies. All-sky radio surveys at different frequenci…
The Distribution of Atomic Hydrogen in the Host Galaxies of FRBs
Hugh Roxburgh, Marcin Glowacki, Clancy W. James +14
We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quad…
