WALLABY Pilot Survey: Public data release of ~1800 HI sources and high-resolution cut-outs from Pilot Survey Phase 2
C. Murugeshan, N. Deg, T. Westmeier +20
We present the Pilot Survey Phase 2 data release for the Wide-field ASKAP L-band Legacy All-sky Blind surveY (WALLABY), carried-out using the Australian SKA Pathfinder (ASKAP). We…
WALLABY Pilot Survey: An 'Almost' Dark Cloud near the Hydra Cluster
T. O'Beirne, L. Staveley-Smith, O. I. Wong +20
We explore the properties of an 'almost' dark cloud of neutral hydrogen (HI) using data from the Widefield ASKAP L-band Legacy All-sky Survey (WALLABY). Until recently, WALLABY J10…
The star formation histories of galaxies in different stages of pre-processing in the Fornax A group
S. I. Loubser, K. Mosia, P. Serra +7
We study the recent star formation histories of ten galaxies in the Fornax A galaxy group, on the outskirts of the Fornax cluster. The group galaxies are gas-rich, and their neutra…
WALLABY Pilot Survey: the Potential Polar Ring Galaxies NGC~4632 and NGC~6156
N. Deg, R. Palleske, K. Spekkens +24
We report on the discovery of two potential polar ring galaxies (PRGs) in the WALLABY Pilot Data Release 1 (PDR1). These untargetted detections, cross-matched to NGC 4632 and NGC 6…
Evidence for a large off-centered galactic outflow and its connection to the extraplanar diffuse ionized gas in IC 1553
Lukas Dirks, Ralf-Jürgen Dettmar, Dominik J. Bomans +2
Aims. We analyze a MUSE optical integral field spectrum of the star-forming edge-on galaxy IC 1553 in order to study its extraplanar diffuse ionized gas (eDIG) and the processes sh…
\HI{} 21cm observations and dynamical modelling of the thinnest galaxy: FGC 2366
K. Aditya, Arunima Banerjee, Peter Kamphuis +3
Superthin galaxies are bulgeless low surface brightness galaxies with unusually high major-to-minor axes ratio of the stellar disc, i.e.,. We present Giant Metrewave Rad…
