FRB 121102 Bursts Show Complex Time-Frequency Structure
J. W. T. Hessels, L. G. Spitler, A. D. Seymour +23
FRB 121102 is the only known repeating fast radio burst source. Here we analyze a wide-frequency-range (1-8 GHz) sample of high-signal-to-noise, coherently dedispersed bursts detec…
First release of Apertif imaging survey data
Elizabeth A. K. Adams, B. Adebahr, W. J. G. de Blok +56
(Abridged) Apertif is a phased-array feed system for WSRT, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated survey program started on 1 July 2019, with th…
Dual-frequency single-pulse study of PSR B0950+08
A. V. Bilous, J. M. Griessmeier, T. Pennucci +33
PSR B0950+08 is a bright non-recycled pulsar whose single-pulse fluence variability is reportedly large. Based on observations at two widely separated frequencies, 55 MHz (NenuFAR)…
Magnetic Field Reversal around an Active Fast Radio Burst
S. Dai, Y. Feng, Y. P. Yang +22
The environment of actively repeating fast radio bursts (FRBs) has been shown to be complex and varying. The recently localized FRB 20190520B is extremely active, has the largest c…
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…
Synthesizing the intrinsic FRB population using frbpoppy
D. W. Gardenier, J. van Leeuwen, L. Connor +1
Fast Radio Bursts (FRBs) are radio transients of an unknown origin. Naturally, we are curious as to their nature. Enough FRBs have been detected for a statistical approach to parts…
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…
Repeating fast radio bursts with WSRT/Apertif
L. C. Oostrum, Y. Maan, J. van Leeuwen +40
Repeating fast radio bursts (FRBs) present excellent opportunities to identify FRB progenitors and host environments, as well as decipher the underlying emission mechanism. Detaile…
The Apertif science verification campaign - Characteristics of polarised radio sources
B. Adebahr, A. Berger, E. A. K. Adams +24
We analyse five early science datasets from the APERture Tile in Focus (Apertif) phased array feed system to verify the polarisation capabilities of Apertif in view of future large…
GReX: An Instrument Overview and New Upper Limits on the Galactic FRB Population
K. A. Shila, S. Niedbalski, L. Connor +14
We present the instrument design and initial results for the Galactic Radio Explorer (GReX), an all-sky monitor for exceptionally bright transients in the radio sky. This instrumen…
Continuum source catalog for the first APERTIF data release
A. M. Kutkin, T. A. Oosterloo, R. Morganti +25
The first data release of Apertif survey contains 3074 radio continuum images covering a thousand square degrees of the sky. The observations were performed during August 2019 to J…
Deep Synoptic Array Science: First FRB and Host Galaxy Catalog
C. J. Law, K. Sharma, V. Ravi +19
Fast Radio Bursts (FRBs) are a powerful and mysterious new class of transient that are luminous enough to be detected at cosmological distances. By associating FRBs to host galaxie…
Synthesizing the repeating FRB population using frbpoppy
D. W. Gardenier, L. Connor, J. van Leeuwen +2
The observed Fast Radio Burst (FRB) population can be divided into one-off and repeating FRB sources. Either this division is a true dichotomy of the underlying sources, or selecti…
Beaming as an explanation of the repetition/width relation in FRBs
L. Connor, M. C. Miller, D. W. Gardenier
It is currently not known if repeating fast radio bursts (FRBs) are fundamentally different from those that have not been seen to repeat. One striking difference between repeaters…
Apertif, Phased Array Feeds for the Westerbork Synthesis Radio Telescope
W. A. van Cappellen, T. A. Oosterloo, M. A. W. Verheijen +87
We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope which has transformed this telescope into a h…
A search for radio emission from double-neutron star merger GW190425 using Apertif
Olivér Boersma, Joeri van Leeuwen, Elizabeth A. K. Adams +26
Detection of the electromagnetic emission from coalescing binary neutron stars (BNS) is important for understanding the merger and afterglow. We present a search for a radio counte…
