A long-period radio transient active for three decades
N. Hurley-Walker, N. Rea, S. J. McSweeney +22
Recently several long-period radio transients have been discovered, with strongly polarised coherent radio pulses appearing on timescales between tens to thousands of seconds [1,2]…
Spectropolarimetric variability in the repeating fast radio burst source FRB 20180301A
Pravir Kumar, Rui Luo, Danny C. Price +9
As the sample size of repeating fast radio bursts (FRBs) has grown, an increasing diversity of phenomenology has emerged. Through long-term multi-epoch studies of repeating FRBs, i…
Searching for broadband pulsed beacons from 1883 stars using neural networks
Vishal Gajjar, Dominic LeDuc, Jiani Chen +19
The search for extraterrestrial intelligence at radio frequencies has largely been focused on continuous-wave narrowband signals. We demonstrate that broadband pulsed beacons are e…
A Matched Survey for the Enigmatic Low Radio Frequency Transient ILT J225347+862146
Yuping Huang, Marin M. Anderson, Gregg Hallinan +3
Discovered in 2011 with LOFAR, the Jy low-frequency radio transient ILT J225347+862146 heralds a potentially prolific population of radio transients at MHz. However, su…
Global Sky Models can Improve Flux Estimates in Pulsar and FRB Studies
Danny C. Price
It is commonplace in pulsar and fast radio burst (FRB) literature to estimate sky temperature by frequency-scaling of the Haslam et al. (1982) 408 MHz map. I suggest that this prac…
Multiband Detection of Repeating FRB 20180916B
Ketan R. Sand, Jakob Faber, Vishal Gajjar +19
We present a multiband study of FRB 20180916B, a repeating source with a 16.3 day periodicity. We report the detection of 4, 1 and 7 bursts from observations spanning 3 days using…
Spectro-temporal Emission from the Galactic Center Magnetar
Akshay Suresh, James M. Cordes, Shami Chatterjee +4
Radio magnetars are exotic sources noted for their diverse spectro-temporal phenomenology and pulse profile variations over weeks to months. Unusual for radio magnetars, the Galact…
The Breakthrough Listen Search For Intelligent Life Near the Galactic Center I
Vishal Gajjar, Karen I. Perez, Andrew P. V. Siemion +23
A line-of-sight towards the Galactic Center (GC) offers the largest number of potentially habitable systems of any direction in the sky. The Breakthrough Listen program is undertak…
Re-Analysis of Breakthrough Listen Observations of FRB 121102: Polarization Properties of Eight New Spectrally Narrow Bursts
Jakob T. Faber, Vishal Gajjar, Andrew P. V. Siemion +15
We report polarization properties for eight narrowband bursts from FRB 121102 that have been re-detected in a high-frequency (4-8 GHz) Breakthrough Listen observation with the Gree…
Detection of a Glitch in PSR J09084913 by UTMOST
Marcus E. Lower, Matthew Bailes, Ryan M. Shannon +20
We report the first detection of a glitch in the radio pulsar PSR J09084913 (PSR B090649) during regular timing observations by the Molonglo Observatory Synthesis Telescope (…
Which bright fast radio bursts repeat?
C. W. James, S. Oslowski, C. Flynn +13
A handful of fast radio bursts (FRBs) are now known to repeat. However, the question remains --- do they all? We report on an extensive observational campaign with the Australian S…
New Limits on the Low-frequency Radio Transient Sky Using 31 hr of All-sky Data with the OVRO-LWA
M. M. Anderson, G. Hallinan, M. W. Eastwood +11
We present the results of the first transient survey from the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) using 31 hr of data, in which we place the most constr…
Faint Repetitions from a Bright Fast Radio Burst Source
Pravir Kumar, R. M. Shannon, Stefan Osłowski +11
We report the detection of repeat bursts from the source of FRB 171019, one of the brightest fast radio bursts (FRBs) detected in the Australian Square Kilometre Array Pathfinder (…
Five new real-time detections of Fast Radio Bursts with UTMOST
W. Farah, C. Flynn, M. Bailes +25
We detail a new fast radio burst (FRB) survey with the Molonglo Radio Telescope, in which six FRBs were detected between June 2017 and December 2018. By using a real-time FRB detec…

Probing the extragalactic fast transient sky at minute timescales with DECam
Igor Andreoni, Jeffrey Cooke, Sara Webb +22
Searches for optical transients are usually performed with a cadence of days to weeks, optimised for supernova discovery. The optical fast transient sky is still largely unexplored…
