No evidence for accretion around the intermediate-mass black hole in Omega Centauri
Angiraben D. Mahida, Arash Bahramian, James C. A. Miller Jones +5
For over a decade, both theoretical predictions and observational studies have suggested that Centauri ( Cen), the most massive Milky Way globular cluster, might harbor an i…
Radio Continuum Studies of Ultra-Compact and Short Orbital Period X-Ray Binaries
Kristen C. Dage, Teresa Panurach, Kwangmin Oh +14
We present the radio continuum counterparts to the enigmatic ultra-compact X-ray binaries (UCXBs); a black hole or neutron star accreting from a hydrogen-deficient white dwarf dono…
The Spectral Behaviour and Variability of Narrow-line Seyfert 1 Galaxies with Australia Telescope Compact Array Observations
Xi Shao, Philip G. Edwards, Jamie Stevens +3
We present multi-frequency radio data for a sample of narrow-line Seyfert 1 galaxies. We first focus on the sub-class of gamma-ray emitting narrow-line Seyfert 1 galaxies, studying…
Do Neutron Star Ultra-Luminous X-Ray Sources Masquerade as Intermediate Mass Black Holes in Radio and X-Ray?
Teresa Panurach, Kristen C. Dage, Ryan Urquhart +8
Ultraluminous X-ray sources (ULXs) were once largely believed to be powered by super-Eddington accretion onto stellar-mass black holes, although in some rare cases, ULXs also serve…
A 2.9-hour periodic radio transient with an optical counterpart
N. Hurley-Walker, S. J. McSweeney, A. Bahramian +12
We present a long-period radio transient (GLEAM-X J0704-37) discovered to have an optical counterpart, consistent with a cool main sequence star of spectral type M3. The radio puls…
The GLEAMing of the first supermassive black holes: III. Radio sources with ultra-faint host galaxies
J. W. Broderick, N. Seymour, G. Drouart +10
We present deep near-infrared -band imaging for 35 of the 53 sources from the high-redshift () radio galaxy candidate sample defined in Broderick et al. (2022). T…
Comprehensive view on a radio-loud QSO: from the radio to the optical/NIR to the X-ray band
Luca Ighina, Alessandro Caccianiga, Alberto Moretti +9
We present a multi-wavelength analysis, from the radio to the X-ray band, of the redshift VIK J231831 radio-loud (RL) quasi stellar object (QSO), one of the most distan…
Long-period radio pulsars: population study in the neutron star and white dwarf rotating dipole scenarios
Nanda Rea, Natasha Hurley-Walker, Celsa Pardo-Araujo +9
The nature of two recently discovered radio emitters with unusually long periods of 18min (GLEAM-X J1627-52) and 21min (GPM J1839-10) is highly debated. Their bright radio emission…
Radio Galaxy Zoo: Unsupervised Clustering of Convolutionally Auto-encoded Radio-astronomical Images
Nicholas O. Ralph, Ray P. Norris, Gu Fang +8
This paper demonstrates a novel and efficient unsupervised clustering method with the combination of a Self-Organising Map (SOM) and a convolutional autoencoder. The rapidly increa…
Discovery of a Pulsar-powered Bow Shock Nebula in the Small Magellanic Cloud Supernova Remnant DEMS5
Rami Z. E. Alsaberi, C. Maitra, M. D. Filipovi'c +32
We report the discovery of a new Small Magellanic Cloud Pulsar Wind Nebula (PWN) at the edge of the Supernova Remnant (SNR)-DEM S5. The pulsar powered object has a cometary morphol…
Radio Galaxy Zoo: Knowledge Transfer Using Rotationally Invariant Self-Organising Maps
T. J. Galvin, M. Huynh, R. P. Norris +7
With the advent of large scale surveys the manual analysis and classification of individual radio source morphologies is rendered impossible as existing approaches do not scale. Th…
