Timothy Davis, Cardiff University In this talk I will describe how mapping the dynamics of gas clouds in the centre of galaxies can help us to constrain a wide range of astrophysical problems. From the enigmatic relation between galaxies and their supermassive black holes, to the suppression of star-formation in dying galaxies, the dynamics of cold gas provides an ideal probe that can help us make progress. I will show how ~ten parsec resolution ALMA observations can be used to estimate the masses of supermassive black holes in galaxies across the Hubble sequence, both dynamically, and via the newly discovered ‘fundamental plane of black hole accretion in the millimetre”. I will show that the deep potential wells of massive galaxies change the small-scale structure of the ISM, suppressing star formation, and helping to keep bulge-dominated objects quenched. Finally I will show first results from the KILOGAS project, a new ALMA legacy survey for the resolved extragalactic ISM, that will map molecular gas and star formation across the Hubble sequence in nearly 500 nearby galaxies.

Prof. Zoran Hadzibabic , Department of Physics, University of Cambridge Nonequilibrium Bose Gas in a Box Prof. Zoran Hadzibabic Department of Physics, University of Cambridge Compared to the traditionally studied harmonically trapped ultracold atomic gases, the spatially uniform gases produced in optical box traps offer many new possibilities for studies of fundamental many-body physics and comparisons with theory. I will give an overview of our recent experiments on out-of-equilibrium box-trapped Bose gases, including the studies of turbulence [1] and of universal coarsening dynamics [2,3]. [1] L. H.
