REGISTRATIONS NOW OPEN

We are entering an exciting era in the study of galaxy formation and evolution. Over the last decade or so, precision experiments have derived stringent limits on the key cosmological parameters, while large galaxy surveys (e.g. 2dF, SDSS, GAMA) have provided compelling insights into galaxy evolution in the nearby Universe using statistical samples of galaxies. Over the coming decade, next generation galaxy surveys (e.g. on ELTs, SKA, etc…) will probe in great detail the complex physical mechanisms that drive galaxy formation and evolution over a wide range of galaxy masses and over a much longer baseline in cosmic time, from the Epoch of Reionization to the present day.

In particular, our understanding of the low-mass regime will be transformed, as multi-object spectrographs and radio telescopes will survey galaxies with stellar masses below 100 million solar masses, and in some cases (e.g. 4MOST WAVES, ASKAP WALLABY/DINGO, SKA) will probe systems as low as a million solar masses. Modelling the properties of low-mass galaxies represents an exciting yet challenging opportunity for galaxy formation simulators. The success or failure of a model is judged typically against its ability to reproduce — broadly — the properties of populations of more massive galaxies. However, low-mass galaxies provide (arguably) the most stringent limits of the models, offering tests of the influence of formation time, gas accretion, feedback, environment, etc…

The aim of this workshop is to bring together world-leading simulators and observers in the field to identify and discuss how the models must be improved to provide robust predictions across the range of galaxy masses, from dwarf-scale upwards. We will focus on developments in modelling star formation, feedback and environmental processing, and what we have learned from small scale simulations and modelling that can be applied to cosmological simulations and semi-analytic models. We will also review the current observational status of dwarf galaxies and determine which observables are the key ones one would want to obtain if we are to apply our simulations to the next generation of surveys.
