MASTER optical detection of the first LIGO/Virgo neutron stars merging GW170817
V. M. Lipunov, E. Gorbovskoy, V. G. Kornilov +30
Following the reported discovery of the gravitational-wave pulse GW170817/ G298048 by three LIGO/Virgo antennae (Abbott et al., 2017a), the MASTER Global Robotic Net telescopes obt…
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)…
The Rapid Reddening and Featureless Optical Spectra of the optical counterpart of GW170817, AT 2017gfo, During the First Four Days
Curtis McCully, Daichi Hiramatsu, D. Andrew Howell +17
We present the spectroscopic evolution of AT 2017gfo, the optical counterpart of the first binary neutron star (BNS) merger detected by LIGO and Virgo, GW170817. While models have…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
Discovery of spin modulated circular polarization from IGR J17014-4306, the remnant of Nova Scorpii 1437 A.D
Stephen B. Potter, David A. H. Buckley
Polarimetry of IGR J1401-4306, a long period (12.7 hours), eclipsing intermediate polar and remnant of Nova Scorpii 1437 A.D., reveals periodic variations of optical circular polar…
SALT Spectropolarimetry and Self-Consistent SED and Polarization Modeling of Blazars
Markus Boettcher, Brian van Soelen, Richard J. Britto +3
We report on recent results from a target-of-opportunity program to obtain spectropolarimetry observations with the Southern African Large Telescope (SALT) on flaring gamma-ray bla…
A VLT-ULTRACAM study of the fast optical quasi-periodic oscillations in the polar V834 Centauri
M. Mouchet, J. -M. Bonnet-Bidaud, L. Van Box Som +6
Quasi-periodic oscillations (QPOs) of a few seconds have been detected in some Polars, the synchronised subclass of cataclysmic systems containing a strongly magnetised white dwarf…
The curtain remains open: NGC 2617 continues in a high state
V. L. Oknyansky, C. M. Gaskell, N. A. Huseynov +17
Optical and near-infrared photometry, optical spectroscopy, and soft X-ray and UV monitoring of the changing look active galactic nucleus NGC 2617 show that it continues to have th…
The 2016 super-Eddington outburst of SMC X-3: X-ray and optical properties and system parameters
L. J. Townsend, J. A. Kennea, M. J. Coe +4
On 2016 July 30 (MJD 57599), observations of the Small Magellanic Cloud by Swift/XRT found an increase in X-ray counts coming from a position consistent with the Be/X-ray binary pu…
