Discovery of the redback millisecond pulsar PSR J1728-4608 with ASKAP
F. Petrou, Y. Wang, N. Hurley-Walker +10
We present the discovery of PSR J1728-4608, a new redback spider pulsar identified in images from the Australian SKA Pathfinder telescope. PSR J1728-4608 is a millisecond pulsar wi…
Searching for Long-Period Radio Transients in ASKAP EMU Data with 10-Second Imaging
Yu Wing Joshua Lee, Yuanming Wang, Manisha Caleb +10
Long-period radio transients (LPTs) are a recently identified phenomenon that challenge our current understanding of compact objects and coherent radio emission mechanisms. These o…
The Dawes Review 13: A New Look at The Dynamic Radio Sky
Tara Murphy, David L. Kaplan
Astronomical objects that change rapidly give us insight into extreme environments, allowing us to identify new phenomena, test fundamental physics, and probe the Universe on all s…
The NANOGrav 15-Year Data Set: Improved Timing Precision With VLBI Astrometric Priors
Sofia V. Sosa Fiscella, Michael T. Lam, Gabriella Agazie +47
Accurate pulsar astrometric estimates play an essential role in almost all high-precision pulsar timing experiments. Traditional pulsar timing techniques refine these estimates by…
Searching for Exotrojans in Pulsar Systems
Jackson D. Taylor, Emmanuel Fonseca, Lankeswar Dey +50
Trojan asteroids are found in the equilateral triangle Lagrange points of the Sun-Jupiter system in great number, though they also exist less prolifically in other parts of the Sol…
Investigating four new candidate redback pulsars discovered in the image plane
Flora Petrou, Natasha Hurley-Walker, Sam McSweeney +12
This paper reports the discovery and follow-up of four candidate redback spider pulsars: GPM J1723-33, GPM J1734-28, GPM J1752-30 and GPM J1815-14, discovered with the Murchison Wi…
Detection of Millimeter-Wavelength Flares from Two Accreting White Dwarf Systems in the SPT-3G Galactic Plane Survey
Y. Wan, J. D. Vieira, P. M. Chichura +96
Blind discoveries of millimeter-wave (mm-wave) transient events in non-targeted surveys, as opposed to follow-up or pointed observations, have only become possible in the past deca…
Discovery of Millisecond Pulsars toward the Galactic Bulge in an Image-based Survey with MeerKAT
Rahul Sengar, Akash Anumarlapudi, David L. Kaplan +3
We report on the follow-up observations of circularly polarized sources identified in the MeerKAT image-based survey of the Galactic bulge. Using the Parkes radio telescope, we obs…
Discovery of Two Highly Scattered Pulsars from Image-Based Circular Polarization Searches with the Australian SKA Pathfinder
Rahul Sengar, David L. Kaplan, Emil Lenc +6
We report the discovery and timing of two pulsars from a sample of four circularly polarized sources identified in radio continuum images taken as part of the Australian SKA Pathfi…
The birth of young radio jets in changing-look AGN: a population study
Sufia Birmingham, Charlotte Ward, Kristina Nyland +4
Changing-Look Active Galactic Nuclei (CLAGN) are a rare subset of AGN that show significant changes to the flux of broad Balmer emission lines. Recent studies of CLAGN, such as 1ES…
ASKAP J144834-685644: a newly discovered long period radio transient detected from radio to X-rays
Akash Anumarlapudi, David L. Kaplan, Nanda Rea +13
Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarized radio bursts with periods varying from a few minutes to a few hours. Fewe…
Constraints on LIGO/Virgo Compact Object Mergers from Late-time Radio Observations
Ashna Gulati, Tara Murphy, Dougal Dobie +6
We present results from a search for radio afterglows of compact object mergers conducted with the Australian SKA Pathfinder. We used data from four epochs of the Rapid ASKAP Conti…
The radio afterglow of the ultra-long GRB 220627A
James K. Leung, Om Sharan Salafia, Cristiana Spingola +13
We present the discovery of the radio afterglow of the most distant ultra-long gamma-ray burst (GRB) detected to date, GRB~220627A at redshift . Its prompt gamma-ray light…
The emission of interpulses by a 6.45-hour period coherent radio transient
Y. W. J. Lee, M. Caleb, Tara Murphy +29
Long-period radio transients are a novel class of astronomical objects characterised by prolonged periods ranging from 18 minutes to 54 minutes. They exhibit highly polarised, cohe…
