Optical transients are objects that change brightness on timescales ranging from minutes to years.
Most observations, however, are made from the Northern Hemisphere. As a result, discoveries at southern declinations are far fewer in number than might be expected, assuming these optical transients should be uniformly distributed across all parts of the sky.
In one proposed project, the one-metre Zadko Telescope will search at southern declinations for some of these ‘missing’ optical transients.
This research will complement those surveys operating in the Northern Hemisphere and contribute to providing more consistent coverage of the sky.
The research will employ a multi-faceted approach to searching for optical transients. By carefully exploiting a single data set, a number of fields of interest can be investigated including near-Earth asteroids and supernovae.
