DOI: 10.1017/pasa.2020.53
Abstract: Abstract We have realised a simple prototype system to perform searches for short timescale optical transients, utilising the novel drift scan imaging technique described by Tingay (2020). We used two coordinated and aligned cameras, with… read more here.

DOI: 10.1093/mnras/stx240
Abstract: We propose that in a small fraction of intermediate luminosity optical transients (ILOTs) powered by a strongly interacting binary system, the ejected mass in the equatorial plane can block the central source from our line… read more here.

DOI: 10.1093/mnras/stz241
Abstract: We present results of the Sky2Night project: a systematic, unbiased search for fast optical transients with the Palomar Transient Factory. We have observed 407deg2 in R-band for eight nights at a cadence of 2 h. During… read more here.

DOI: 10.1134/s1063778821130251
Abstract: Abstract A wide-angle Cerenkov array TAIGA-HiSCORE (FOV $$\sim$$ 0.6 sr), was originally created as a part of TAIGA installation for high-energy gamma-ray astronomy and cosmic ray physics. Array now consist on nearly 100 optical stations… read more here.
