Abell 1451 and 1RXS J131423.6-251521: a multi-wavelength study of two dynamically perturbed clusters of galaxies
I. Valtchanov, T. Murphy, M. Pierre +2
We present results from optical, X-ray and radio observations of two X-ray bright (L_X ~ 10^{45} erg/s) galaxy clusters. A1451 is at redshift z=0.1989 and has line-of-sight velocit…
X-ray/Optical analysis of the cluster of galaxies Abell 1300: Indications of a post-merger at z = 0.31
L. Lemonon, M. Pierre, R. Hunstead +3
We present ROSAT PSPC and HRI observations of the distant cluster A1300 (z = 0.3071) in conjunction with optical data, to investigate the physics of the intra-cluster medium and th…
The UTMOST Survey for Magnetars, Intermittent pulsars, RRATs and FRBs I: System description and overview
V. Venkatraman Krishnan, C. Flynn, W. Farah +22
We describe the ongoing `Survey for Magnetars, Intermittent pulsars, Rotating radio transients and Fast radio bursts' (SMIRF), performed using the newly refurbished UTMOST telescop…
XTE J1550-564: A superluminal ejection during the September 1998 outburst
D. Hannikainen, D. Campbell-Wilson, R. Hunstead +5
In 1998 September, the X-ray transient XTE J1550-564 underwent a major outburst in soft and hard X-rays, followed by a radio flare. Australian Long Baseline Array images obtained s…
Radio Emission from the X-ray transient XTE J1550-564
D. Hannikainen, K. Wu, Campbell-Wilson +6
We report multifrequency radio observations of XTE J1550-564 obtained with the Molonglo Observatory Synthesis Telescope and the Australia Telescope Compact Array at the time of its…
FRB microstructure revealed by the real-time detection of FRB170827
W. Farah, C. Flynn, M. Bailes +24
We report a new Fast Radio Burst (FRB) discovered in real-time as part of the UTMOST project at the Molonglo Observatory Synthesis Radio Telescope (MOST). FRB170827 is the first de…
The 1998 outburst of XTE J1550-564: a model based on multiwavelength observations
K. Wu, R. Soria, D. Campbell-Wilson +6
The 1998 September outburst of the black-hole X-ray binary XTE J1550-564 was monitored at X-ray, optical and radio wavelengths. We divide the outburst sequence into five phases and…
Five new real-time detections of Fast Radio Bursts with UTMOST
W. Farah, C. Flynn, M. Bailes +25
We detail a new fast radio burst (FRB) survey with the Molonglo Radio Telescope, in which six FRBs were detected between June 2017 and December 2018. By using a real-time FRB detec…
A pilot survey for transients and variables with the Australian Square Kilometre Array Pathfinder
S. Bhandari, K. W. Bannister, T. Murphy +20
We present a pilot search for variable and transient sources at 1.4 GHz with the Australian Square Kilometre Array Pathfinder (ASKAP). The search was performed in a 30 deg ar…
Defying jet-gas alignment in two radio galaxies at z~2 with extended light profiles: Similarities to brightest cluster galaxies
C. Collet, N. P. H. Nesvadba, C. De Breuck +7
We report the detection of extended warm ionized gas in two powerful high-redshift radio galaxies, NVSS J210626-314003 at z=2.10 and TXS 2353-003 at z=1.49, that does not appear to…
The first ISO ERO: a dusty quasar at z = 1.5
M. Pierre, C. Lidman, R. Hunstead +8
We report the discovery of an extremely red object (ERO) in a medium-deep ISOCAM extragalactic survey. The object is also a radio source. Subsequent VLT NIR spectroscopy revealed a…
Kinematic signatures of AGN feedback in moderately powerful radio galaxies at z~2 observed with SINFONI
C. Collet, N. P. H. Nesvadba, C. De Breuck +6
Most successful galaxy formation scenarios now postulate that the intense star formation in massive, high-redshift galaxies during their major growth period was truncated when powe…
The radio spectral energy distribution of infrared-faint radio sources
A. Herzog, R. P. Norris, E. Middelberg +57
Infrared-faint radio sources (IFRS) are a class of radio-loud (RL) active galactic nuclei (AGN) at high redshifts (z > 1.7) that are characterised by their relative infrared faintn…
Stellar populations in a complete sample of local radio galaxies
D. Raimann, T. Storchi-Bergmann, H. Quintana +2
We investigate the nature of the continuum emission and stellar populations in the inner 1-3 kiloparsecs of a complete sample of twenty-four southern radio galaxies, and compare th…
