The galaxy morphology-density relation in the EAGLE simulation
Joel Pfeffer, Mitchell K. Cavanagh, Kenji Bekki +4
The optical morphology of galaxies is strongly related to galactic environment, with the fraction of early-type galaxies increasing with local galaxy density. In this work we prese…
Peekaboo: the extremely metal poor dwarf galaxy HIPASS J1131-31
I. D. Karachentsev, L. N. Makarova, B. S. Koribalski +3
The dwarf irregular galaxy HIPASS J1131-31 was discovered as a source of HI emission at low redshift in such close proximity of a bright star that we call it Peekaboo. The galaxy r…
WALLABY Pilot Survey: Public release of HI kinematic models for more than 100 galaxies from phase 1 of ASKAP pilot observations
N. Deg, K. Spekkens, T. Westmeier +29
We present the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) Pilot Phase I HI kinematic models. This first data release consists of HI observations of three fields i…
WALLABY Pilot Survey: Public release of HI data for almost 600 galaxies from phase 1 of ASKAP pilot observations
T. Westmeier, N. Deg, K. Spekkens +49
We present WALLABY pilot data release 1, the first public release of HI pilot survey data from the Wide-field ASKAP L-band Legacy All-sky Blind Survey (WALLABY) on the Australian S…
CO(=1-0) mapping survey of 64 galaxies in the Fornax cluster with the ALMA Morita array
Kana Morokuma-Matsui, Kenji Bekki, Jing Wang +18
We conduct a CO(=1-0) (hereafter CO) mapping survey of 64 galaxies in the Fornax cluster using the ALMA Morita array in cycle 5. CO emission is detected from 23 ou…
New ASKAP Radio Supernova Remnants and Candidates in the Large Magellanic Cloud
Luke M. Bozzetto, Miroslav D. Filipović, H. Sano +34
We present a new Australian Square Kilometre Array Pathfinder (ASKAP) sample of 14 radio Supernova Remnant (SNR) candidates in the Large Magellanic Cloud (LMC). This new sample is…
Collimation of the kiloparsec-scale radio jets in NGC 2663
Velibor Velović, M. D. Filipović, L. Barnes +25
We present the discovery of highly-collimated radio jets spanning a total of 355 kpc around the nearby elliptical galaxy NGC 2663, and the possible first detection of recollimation…
Insights on the origin of ORCs from cosmological simulations
Klaus Dolag, Ludwig M. Böss, Bärbel S. Koribalski +2
We investigate shock structures driven by merger events in high-resolution simulations that result in a galaxy with a virial mass M ~ 1e12 Msol. We find that the sizes and morpholo…
Radio fossils, relics, and haloes in Abell 3266: cluster archaeology with ASKAP-EMU and the ATCA
C. J. Riseley, E. Bonnassieux, T. Vernstrom +21
Abell 3266 is a massive and complex merging galaxy cluster that exhibits significant substructure. We present new, highly sensitive radio continuum observations of Abell 3266 perfo…
ALMA/ACA CO Survey of the IC 1459 and NGC 4636 Groups: Environmental Effects on the Molecular Gas of Group Galaxies
Bumhyun Lee, Jing Wang, Aeree Chung +30
We present new results of a 12CO(J=1-0) imaging survey using the Atacama Compact Array (ACA) for 31 HI detected galaxies in the IC 1459 and NGC 4636 groups. This is the first CO im…
Deep ASKAP EMU Survey of the GAMA23 field: Properties of radio sources
Gülay Gürkan, I. Prandoni, A. O'Brien +19
We present the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the Galaxy and Mass Assembly (GAMA)-23h field. The survey was carried out at 887.5 MHz and cover…
Mysterious Odd Radio Circle near the Large Magellanic Cloud -- An Intergalactic Supernova Remnant?
Miroslav D. Filipović, J. L. Payne, R. Z. E. Alsaberi +48
We report the discovery of J0624-6948, a low-surface brightness radio ring, lying between the Galactic Plane and the Large Magellanic Cloud (LMC). It was first detected at 888 MHz…
Radio footprints of a minor merger in the Shapley Supercluster: From supercluster down to galactic scales
T. Venturi, S. Giacintucci, P. Merluzzi +29
The Shapley Supercluster () contains several tens of gravitationally bound clusters and groups, making it it is an ideal subject for radio studies of…
