Head-Tail Galaxies: Beacons of High-Density Regions in Clusters
Minnie Y. Mao, Melanie Johnston-Hollitt, Jamie B. Stevens +1
Using radio data at 1.4 GHz from the ATCA we identify five head-tail (HT) galaxies in the central region of the Horologium-Reticulum Supercluster (HRS). Physical parameters of the…
Radio observations of the Horologium-Reticulum Supercluster -I. A3158: Excess star-forming galaxies in a merging cluster?
M. Johnston-Hollitt, M. Sato, J. A. Gill +2
We present 1.4 and 2.5 GHz Australia Telescope Compact Array (ATCA) observations of the galaxy cluster A3158 (z=0.0597) which is located within the central part of the Horologium-R…
The optical morphology of A3667 re-examined
M. Johnston-Hollitt, R. W. Hunstead, E. Corbett
The galaxy cluster A3667 was observed using the Two-degree Field (2dF) multifibre spectroscopic system on the Anglo-Australian Telescope in a program designed to examine the veloci…
A search for 22-GHz water masers within the giant molecular cloud associated with RCW106
S. L. Breen, S. P. Ellingsen, M. Johnston-Hollitt +7
We report the results of a blind search for 22-GHz water masers in two regions, covering approximately half a square degree, within the giant molecular cloud associated with RCW 10…
Radio views of cosmic reionization
M. Valdes, B. Ciardi, A. Ferrara +2
We use numerical simulations of cosmic reionization and radiative processes related to the HI 21 cm emission line to produce synthetic radio maps as seen by next generation radio t…
Redshifts and Velocity Dispersions of Galaxy Clusters in the Horologium-Reticulum Supercluster
M. C. Fleenor, J. A. Rose, W. A. Christiansen +4
We present 118 new optical redshifts for galaxies in 12 clusters in the Horologium-Reticulum supercluster (HRS) of galaxies. For 76 galaxies, the data were obtained with the Dual B…
