An unidentified Fermi source emitting radio bursts in the Galactic bulge

We report on the detection of radio bursts from the Galactic bulge using the real-time transient detection and localization system, realfast. The pulses were detected commensally o…
Temporal and Spectral Properties of the Persistent Radio Source Associated with FRB 20190520B with the VLA
Xian Zhang, Wenfei Yu, Casey Law +12
Among more than 800 known fast radio bursts (FRBs), only two, namely FRB 20121102A and FRB 20190520B, are confirmed to be associated with a persistent radio sources (PRS). Here we…
On the radio spectra of Galactic millisecond pulsars
Kshitij Aggarwal, Duncan. R. Lorimer
With recent advances in the sensitivity of radio surveys of the Galactic disk, the number of millisecond pulsars (MSPs) has increased substantially in recent years such that it is…
Magnetic field reversal in the turbulent environment around a repeating fast radio burst
Reshma Anna-Thomas, Liam Connor, Shi Dai +27
Fast radio bursts (FRBs) are brief, intense flashes of radio waves from unidentified extragalactic sources. Polarized FRBs originate in highly magnetized environments. We report ob…
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…
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…
A Distant Fast Radio Burst Associated to its Host Galaxy with the Very Large Array
C. J. Law, B. J. Butler, J. X. Prochaska +17
We present the discovery and subarcsecond localization of a new Fast Radio Burst with the Karl G. Jansky Very Large Array and realfast search system. The FRB was discovered on 2019…
VLA/Realfast Detection of a Burst from FRB180916.J0158+65 and Tests for Periodic Activity

A repeating fast radio burst source localised to a nearby spiral galaxy
B. Marcote, K. Nimmo, J. W. T. Hessels +51
Fast radio bursts (FRBs) are brief, bright, extragalactic radio flashes. Their physical origin remains unknown, but dozens of possible models have been postulated. Some FRB sources…
Modeling the uncertainties of solar-system ephemerides for robust gravitational-wave searches with pulsar timing arrays
M. Vallisneri, S. R. Taylor, J. Simon +61
The regularity of pulsar emissions becomes apparent once we reference the pulses' times of arrivals to the inertial rest frame of the solar system. It follows that errors in the de…
