Consistency of cosmological datasets meeting

Data from Planck are beautifully consistent with the ΛCDM cosmology. Yet a number of other astrophysical datasets appear to be in tension with the cosmological parameters measured by Planck. Examples include local measurements of the Hubble constant, the amplitude of the mass fluctuations inferred from weak galaxy lensing and cluster abundances and the high redshift baryon oscillation acoustic scale measurements from the Lyα forest. The aim of the workshop is to bring together leading experts and key young people working on these topics to engage in a frank discussion on whether these tensions exist, whether they are symptoms of systematics in the data, or whether they indicate the need for new physics.

LSST UK Multi-Wavelength Data Fusion Workshop

A workshop to bring together experts interested in combining multi-wavelength data from X-ray, infra-red, millimeter and radio surveys with optical data from LSST. We will discuss the challenges of combining key multi-wavelength datasets from surveys with UK leadership (e.g. XMM-Newton, VISTA, Euclid, Herschel, LOFAR, SKA) with the LSST data. We will put together a plan for bench-marking and testing existing algorithms as well as developing new methodology for data-fusion that will be relevant in the LSST era.

Emission Line Galaxies with MOS: from cosmic noon to the reionization era

Galaxies showing strong emission lines are precious laboratories to study the physical mechanisms driving and regulating star formation through cosmic time. With the advent of the last generation of optical and near-infrared Multi Object and Integral Field Spectrographs (MOS, IFS), we have entered in a new golden era for emission line studies.

The disc migration issue: from protoplanets to supermassive black holes

This workshop is motivated by the broad similarities surrounding the theory of disc mediated migration on scales ranging from protoplanetary discs to galactic nuclei. Migration theory thus underpins our understanding of some of the most topical problems in contemporary astrophysics, i.e. the establishment of planetary system `architecture' and the processes driving the merging of black holes.

Galaxy clusters: physics laboratories and cosmological probes

Galaxy clusters are unique astrophysical laboratories in which the powerful interaction of supermassive black holes with the surrounding intracluster medium, the complex effects of the cluster environment on galaxies, as well as a wide range of non-thermal processes like magnetic field amplification and cosmic ray acceleration can be studied.
