Estimating the spectral resolution of a radio data cube from its noise properties
P. Serra, G. Mulas, K. M. Hess +4
We present a new method to estimate the spectral resolution of a radio data cube from its noise properties. We assume that the data cube is the result of the convolution of a spect…
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: The diversity of HI structural parameters in nearby galaxies
T. N. Reynolds, B. Catinella, L. Cortese +22
We investigate the diversity in the sizes and average surface densities of the neutral atomic hydrogen (HI) gas discs in ~280 nearby galaxies detected by the Widefield ASKAP L-band…
MIGHTEE-HI: Evolution of HI scaling relations of star-forming galaxies at
Francesco Sinigaglia, Giulia Rodighiero, Ed Elson +33
We present the first measurements of HI galaxy scaling relations from a blind survey at . We perform spectral stacking of 9023 spectra of star-forming galaxies undetected i…
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…
CHILES VII: Deep Imaging for the CHILES project, a SKA prototype
R. Dodson, E. Momjian, D. J. Pisano +16
Radio Astronomy is undergoing a renaissance, as the next-generation of instruments provides a massive leap forward in collecting area and therefore raw sensitivity. However, to ach…
Physics of radio emission in the long-period pulsars
P B Jones
Recent multi-frequency measurements of pulse widths W50 for the long-period pulsar J0250+5854 by Agar et al provide a unique insight to the emission process owing to its small pola…
WALLABY Pilot Survey: the diversity of ram pressure stripping of the galactic HI gas in the Hydra Cluster
Jing Wang, Lister Staveley-Smith, Tobias Westmeier +26
This study uses HI image data from the WALLABY pilot survey with the ASKAP telescope, covering the Hydra cluster out to 2.5. We present the projected phase-space distribut…
Apertif view of the OH Megamaser IRAS 10597+5926: OH 18 cm satellite lines in wide-area HI surveys
Kelley M. Hess, H. Roberts, H. Dénes +26
We present the serendipitous detection of the two main OH maser lines at 1667 and 1665 MHz associated with IRAS 10597+5926 at z = 0.19612 in the untargeted Apertif Wide-area Extrag…
SlicerAstro: a 3-D interactive visual analytics tool for HI data
D. Punzo, J. M. van der Hulst, J. B. T. M. Roerdink +2
SKA precursors are capable of detecting hundreds of galaxies in HI in a single 12 hours pointing. In deeper surveys one will probe more easily faint HI structures, typically locate…
Finding faint HI structure in and around galaxies: scraping the barrel
D. Punzo, J. M. van der Hulst, J. B. T. M. Roerdink
Soon to be operational HI survey instruments such as APERTIF and ASKAP will produce large datasets. These surveys will provide information about the HI in and around hundreds of ga…
The Bluedisk Survey: molecular gas distribution and scaling relations in the context of galaxy evolution
D. Cormier, F. Bigiel, J. Wang +8
One of the key goals of the Bluedisk survey is to characterize the impact of gas accretion in disc galaxies in the context of galaxy evolution. It contains 50 disc galaxies in the…
The Void Galaxy Survey: Galaxy Evolution and Gas Accretion in Voids
Kathryn Kreckel, Jacqueline H. van Gorkom, Burcu Beygu +4
Voids represent a unique environment for the study of galaxy evolution, as the lower density environment is expected to result in shorter merger histories and slower evolution of g…
Working Group Summary - Local Universe
E. Tolstoy, G. Battaglia, R. Beck +4
This is a summary of the discussions that took place in the working group dedicated to studies of the Local Universe. The authors are listed in alphabetical order, after the workin…
Local Galaxies as Damped Ly-Alpha Analogs
M. A. Zwaan, J. M. van der Hulst, F. H. Briggs +2
We calculate in detail the expected properties of low redshift DLA systems under the assumption that they arise in the gaseous disks of galaxies like those in the z=0 population. A…
Galaxy Evolution and Cosmology with the Square Kilometre Array
S. Rawlings, F. B. Abdalla, S. L. Bridle +4
The present-day Universe is seemingly dominated by dark energy and dark matter, but mapping the normal (baryonic) content remains vital for both astrophysics - understanding how ga…
