Discovery of an Extremely Luminous Sporadic Radio Pulsar
Fengqiu Adam Dong, Robert Main, Jackson D. Taylor +25
We have discovered PSR J2108+5055, an extremely luminous but sporadic mode-changing rotating radio transient (RRAT), with a period of 0.495 s using the Canadian Hydrogen Intensity…
The Astrophysics of Fast Radio Bursts
Alice P. Curtin, Marcin Gawroński, Jason Hessels +11
Fast radio bursts (FRBs) provide a glimpse of high-energy astrophysical phenomena in other galaxies. They point the way to extreme conditions that are currently undetectable by any…
A steadily declining dispersion measure for the repeating fast radio burst FRB 20220529A: Evidence for an FRB engine embedded in an expanding supernova remnant
Ayush Pandhi, Kenzie Nimmo, Shion Andrew +29
We present the discovery and subsequent 3.2 year monitoring campaign of the repeating fast radio burst FRB 20220529A with CHIME/FRB. We observe a gradual dispersion measure (DM) de…
LOFAR constraints on the repetition & environments of CHIME FRBs
Pragya Chawla, Akshatha Gopinath, Ninisha Manaswini +5
The behaviour of fast radio bursts (FRBs) at radio frequencies <400 MHz is not well understood due to very few detections, with only two known sources detected below 300 MHz. Chara…
CHIME/FRB Outriggers: Design Overview
FRB Collaboration, Mandana Amiri, Bridget C. Andersen +66
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has emerged as the world's premier facility for studying fast radio bursts (FRBs) through its fast transient search backe…
PRECISE localizations of repeating Fast Radio Bursts
B. Marcote, F. Kirsten, J. W. T. Hessels +2
Fast Radio Bursts (FRBs) are extremely luminous and brief signals (with duration of milliseconds or even shorter) of extragalactic origin. Despite the fact that hundreds of FRBs ha…
First Discovery of a Fast Radio Burst at 350 MHz by the GBNCC Survey
E. Parent, P. Chawla, V. M. Kaspi +26
We report the first discovery of a fast radio burst (FRB), FRB 20200125A, by the Green Bank Northern Celestial Cap (GBNCC) Pulsar Survey conducted with the Green Bank Telescope at…
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…
Highest-frequency detection of FRB 121102 at 4-8 GHz using the Breakthrough Listen Digital Backend at the Green Bank Telescope
V. Gajjar, A. P. V. Siemion, D. C. Price +28
We report the first detections of the repeating fast radio burst source FRB 121102 above 5.2 GHz. Observations were performed using the 48 GHz receiver of the Robert C. Byrd Gre…
Tests of Gravitational Symmetries with Pulsar Binary J1713+0747
W. W. Zhu, G. Desvignes, N. Wex +50
Symmetries play an important role in modern theories of gravity. The strong equivalence principle (SEP) constitutes a collection of gravitational symmetries which are all implement…
An extreme magneto-ionic environment associated with the fast radio burst source FRB 121102
D. Michilli, A. Seymour, J. W. T. Hessels +31
Fast radio bursts (FRBs) are millisecond-duration, extragalactic radio flashes of unknown physical origin. FRB 121102, the only known repeating FRB source, has been localized to a…
Targeted millisecond pulsar surveys of Fermi gamma-ray sources with LOFAR
C. G. Bassa, Z. Pleunis, J. W. T. Hessels +7
We have used LOFAR to perform targeted millisecond pulsar surveys of Fermi gamma-ray sources. Operating at a center frequency of 135 MHz, the surveys use a novel semi-coherent dedi…
X-rays from the mode-switching PSR B0943+10
S. Mereghetti, L. Kuiper, A. Tiengo +15
New simultaneous X-ray and radio observations of the archetypal mode-switching pulsar PSR B0943+10 have been carried out with XMM-Newton and the LOFAR, LWA and Arecibo radio telesc…
FRB 121102 is coincident with a star forming region in its host galaxy
