In recent years, the world of transient astrophysics has undergone a paradigm shift. New wide-field and rapid surveys, including ATLAS, GOTO, and ZTF, are producing vast amounts of astronomical data every night. This has presented new opportunities for physical insights, but also new theoretical and technical challenges.
The collection of large, statistical, and homogeneous samples of transients has enabled a deeper theoretical understanding of their elusive nature. This includes detailed studies into population statistics, the rates of transients, the connection between transients and their host galaxies, cosmological applications, and more. At the same time, new and unusual transient types that confound current theoretical models are also being discovered at a rapid pace. These transients reside in previously under-populated regions of the luminosity-duration phase space and therefore could represent gaps in our understanding of stellar evolution or explosion mechanisms.
On the technical side, the sheer volume of data produced raises the question: how best do we utilise it for scientific gain? This is particularly pressing as upcoming surveys, such as LSST, will increase the number of transient discoveries even further and could become overwhelming. To that end, machine learning techniques have gained considerable attention and are now integral to various aspects of transient astrophysics, including the identification of newly discovered transients, contextual and photometric classification of transients, and even the analysis of transients through clustering and rapid modelling. As the data deluge continues, machine learning techniques will become vital to ensure data sets are fully exploited.
The aim of this informal meeting is to bring together members of the UK and wider transient community actively working on or generally interested in the broad topic of machine learning, to share ideas about techniques currently in use, current and future applications, and to foster collaboration. We invite contributed talks from members of the community, focused on their use cases and machine learning applications, and aim to have more detailed hands-on sessions centred around getting started with machine learning.
