On the Fast Radio Burst and Persistent Radio Source Populations
C. J. Law, L. Connor, K. Aggarwal
The first Fast Radio Burst (FRB) to be precisely localized was associated with a luminous persistent radio source (PRS). Recently, a second FRB/PRS association was discovered for a…
Search for fast radio transients using Arecibo drift-scan observations at 1.4 GHz
B. B. P. Perera, A. J. Smith, S. Vaddi +12
We conducted a drift-scan observation campaign using the 305-m Arecibo telescope in January and March 2020 when the observatory was temporarily closed during the intense earthquake…
A repeating fast radio burst associated with a persistent radio source
C. -H. Niu, K. Aggarwal, D. Li +32
The dispersive sweep of fast radio bursts (FRBs) has been used to probe the ionized baryon content of the intergalactic medium, which is assumed to dominate the total extragalactic…
Observational effects of banded repeating FRBs
Kshitij Aggarwal
Recent observations have shown that repeating Fast Radio Bursts (FRBs) exhibit band-limited emission, whose frequency-dependent amplitude can be modeled using a Gaussian function.…
Characterizing the FRB host galaxy population and its connection to transients in the local and extragalactic Universe
Shivani Bhandari, Kasper E. Heintz, Kshitij Aggarwal +23
We present the localization and host galaxies of one repeating and two apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and localized with the Karl G. Jansky V…
Comprehensive analysis of a dense sample of FRB 121102 bursts
Kshitij Aggarwal, Devansh Agarwal, Evan F. Lewis +5
We present an analysis of a densely repeating sample of bursts from the first repeating fast radio burst, FRB 121102. We reanalysed the data used by Gourdji et al. (2019) and detec…
The host galaxy and persistent radio counterpart of FRB 20201124A
Vikram Ravi, Casey J. Law, Dongzi Li +7
The physical properties of fast radio burst (FRB) host galaxies provide important clues towards the nature of FRB sources. The 16 FRB hosts identified thus far span three orders of…
A repeating fast radio burst source in a globular cluster
F. Kirsten, B. Marcote, K. Nimmo +63
Fast radio bursts (FRBs) are exceptionally luminous flashes of unknown physical origin, reaching us from other galaxies (Petroff et al. 2019). Most FRBs have only ever been seen on…
Robust Assessment of Clustering Methods for Fast Radio Transient Candidates
Kshitij Aggarwal, Sarah Burke-Spolaor, Casey J. Law +7
Fast radio transient search algorithms identify signals of interest by iterating and applying a threshold on a set of matched filters. These filters are defined by properties of th…
Multi-wavelength follow-up of FRB 180309
Kshitij Aggarwal, Sarah Burke-Spolaor, Nicolas Tejos +5
We report on the results of multi-wavelength follow-up observations with Gemini, VLA, and ATCA, to search for a host galaxy and any persistent radio emission associated with FRB 18…
Probabilistic Association of Transients to their Hosts (PATH)
Kshitij Aggarwal, Tamás Budavári, Adam T. Deller +4
We introduce a new method to estimate the probability that an extragalactic transient source is associated with a candidate host galaxy. This approach relies solely on simple obser…
Reprocessing of a Green Bank 43-meter Telescope Survey of Unidentified Bright Radio Sources for Pulsars and Radio Bursts
F. Crawford, J. Margeson, B. Nguyen +4
We have reprocessed a set of observations of 75 bright, unidentified, steep-spectrum polarized radio sources taken with the Green Bank 43-m telescope to find previously undetected…
