The Orbital Period vs. Absolute Magnitude Relationship of Intermediate Polars: Implications for Low States and Outbursts
Koji Mukai, Magaretha L. Pretorius
Recent advances in time-domain astronomy have led to fresh observational insights into intermediate polars, a subtype of magnetic cataclysmic variables generally accreting via a pa…
Nine-hour X-ray quasi-periodic eruptions from a low-mass black hole galactic nucleus
G. Miniutti, R. D. Saxton, M. Giustini +11
In the past two decades, high amplitude electromagnetic outbursts have been detected from dormant galaxies and often attributed to the tidal disruption of a star by the central bla…
A comparison between SALT/SAAO observations and kilonova models for AT 2017gfo: the first electromagnetic counterpart of a gravitational wave transient - GW170817
David A. H. Buckley, Igor Andreoni, Sudhanshu Barway +13
We report on SALT low resolution optical spectroscopy and optical/IR photometry undertaken with other SAAO telescopes (MASTER-SAAO and IRSF) of the kilonova AT 2017gfo (aka SSS17a)…
On the use of variability time-scales as an early classifier of radio transients and variables
M. Pietka, T. D. Staley, M. L. Pretorius +1
We have shown previously that a broad correlation between the peak radio luminosity and the variability time-scales, approximately L ~ t^5, exists for variable synchrotron emitting…
The peculiar mass-loss history of SN 2014C as revealed through AMI radio observations
G. E. Anderson, A. Horesh, K. P. Mooley +12
We present a radio light curve of supernova (SN) 2014C taken with the Arcminute Microkelvin Imager (AMI) Large Array at 15.7 GHz. Optical observations presented by Milisavljevic et…
Two fast X-ray transients in archival Chandra data
A. Glennie, P. G. Jonker, R. P. Fender +2
We present the discovery of two new X-ray transients in archival Chandra data. The first transient, XRT 110103, occurred in January 2011 and shows a sharp rise of at least three or…
