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…
Discovery of Main-sequence Radio Pulse emitters from widefield sky surveys
Barnali Das, Matt E. Shultz, Joshua Pritchard +6
Magnetic AB stars are known to produce periodic radio pulses by the electron cyclotron maser emission (ECME) mechanism. Only 19 such stars, known as 'Main-sequence Radio Pulse emit…
VAST-MeMeS: Characterising non-thermal radio emission from magnetic massive stars using the Australian SKA Pathfinder
Barnali Das, Laura N. Driessen, Matt E. Shultz +7
Magnetic massive stars are stars of spectral types O, B and A that harbour kG strength (mostly dipolar) surface magnetic fields. Their non-thermal radio emission has been de…
The discovery of a 41s radio pulsar PSR J0311+1402 with ASKAP
Yuanming Wang, Pavan Uttarkar, Ryan Shannon +16
The emerging population of long-period radio transients (LPTs) show both similarities and differences with normal pulsars. A key difference is that their radio emission is too brig…
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Ziteng Wang, Nanda Rea, Tong Bao +46
