Star-forming edge-on galaxies often exhibit extended halo radiation in multiple bands, providing ideal laboratories for studying the transfer of matter from the disk to the halo. W…
A radio transient with unusually slow periodic emission
N. Hurley-Walker, X. Zhang, A. Bahramian +7
The high-frequency radio sky is bursting with synchrotron transients from massive stellar explosions and accretion events, but the low-frequency radio sky has so far been quiet bey…

The next-generation Very Large Array (ngVLA) is intended to be the premier centimeter-wavelength facility for astronomy and astrophysics, building on the substantial scientific leg…
On the nature of LOFAR RMs and new constraints on magnetic fields in cosmic filaments and on magnetogenesis scenarios
E. Carretti, F. Vazza, S. P. O'Sullivan +6
The measurement of magnetic fields in cosmic web filaments can be used to reveal the magnetogenesis of the Universe. In previous work, we produced first estimates of the field stre…
The twisted jets and magnetic fields of the extended radio galaxy 4C 70.19
M. Weżgowiec, M. Jamrozy, K. T. Chyży +4
The appearance of the jets and lobes of some radio galaxies makes it difficult to assign them to a known class of objects. This is often due to the activity of the central engine a…
eDIG-CHANGES III: the lagging eDIG revealed by multi-slit spectroscopy of NGC 891
Li-Yuan Lu, Jiang-Tao Li, Carlos J. Vargas +9
The kinematic information of the extraplanar diffuse ionized gas (eDIG) around galaxies provides clues to the origin of the gas. The eDIG-CHANGES project studies the physical and k…
Ram-pressure stripped radio tails detected in the dynamically active environment of the Shapley Supercluster
P. Merluzzi, T. Venturi, G. Busarello +13
We study the radio continuum emission of four galaxies experiencing ram-pressure stripping in four clusters of the Shapley supercluster at redshift z~0.05. Multi-band (235-1367 MHz…
The Sydney Radio Star Catalogue: properties of radio stars at megahertz to gigahertz frequencies
Laura N. Driessen, Joshua Pritchard, Tara Murphy +12
We present the Sydney Radio Star Catalogue, a new catalogue of stars detected at megahertz to gigahertz radio frequencies. It consists of 839 unique stars with 3,405 radio detectio…
Prototype Faraday rotation measure catalogs from the Polarisation Sky Survey of the Universe's Magnetism (POSSUM) pilot observations
S. Vanderwoude, J. L. West, B. M. Gaensler +12
The Polarisation Sky Survey of the Universe's Magnetism (POSSUM) will conduct a sensitive 1 GHz radio polarization survey covering 20 000 square degrees of the Southern sky w…
Multi-epoch sampling of the radio star population with the Australian SKA Pathfinder
Joshua Pritchard, Tara Murphy, George Heald +5
The population of radio-loud stars has to date been studied primarily through either targeted observations of a small number of highly active stars or widefield, single-epoch surve…
The Rapid ASKAP Continuum Survey V: cataloguing the sky at 1367.5 MHz and the second data release of RACS-mid
S. W. Duchesne, J. A. Grundy, George H. Heald +10
The Australian SKA Pathfinder (ASKAP) has surveyed the sky at multiple frequencies as part of the Rapid ASKAP Continuum Survey (RACS). The first two RACS observing epochs, at 887.5…
