Abstract
Our research aims to investigate a range of high-priority science topics in these areas:
i. studying high-energy and high-redshift transients and the relation of transients to gravitational wave events
ii. investigating the growth and evolution of the first stars and black holes in galaxies
iii. determining the properties of powerful active galactic nuclei including the Broad Line Region
iv. measuring the fundamental properties of white dwarf stars
v. investigating the properties of exoplanets, brown dwarfs and low mass stars
vi. investigating accretion processes
vii exploring the formation of planets
We will deliver this programme by carrying out observations using a broad range of ground and space based observing facilities, including XMM-Newton, HST, Swift, GAIA, JWST, ALMA, VLT, WHT, INT, LT, NGTS, GOTO and SAAO, and by conducting numerical simulations using major High Performance Computer facilities such as DiRAC.

| Organisation | European Southern Observatory (ESO) |
| Country | Germany |
| Sector | Charity/Non Profit |
| PI Contribution | Our Leicester team is part of a large international collaboration to use ESO telescopes and others, for follow-up of the electromagnetic counterparts of gravitational wave events. Tanvir is a member of the governing council of ENGRAVE. |
| Collaborator Contribution | The collaboration has over 250 members, who bring diverse expertise. In particular, real time duties are the responsibility of a core group of about 40 people currently. |
| Impact | One paper submitted so far. |

| PI Contribution | Tanvir is PI of a large collaboration whose goal is to obtain optical/nIR follow-up observations of gamma-ray bursts using ESO facilities. |
| Collaborator Contribution | The collaboration consists of a (geographically spread) core group who trigger and analyse the rapid target-of-opportunity observations, plus a wider group who contribute to planning, interpretation and analysis for at least some of the specialised sub-projects. (the number of partner institutions in this sense is large and fluid, and they are not individually listed. Similarly the value of the in-kind contributions is not well defined; except for ESO for which the value recorded here is a rough estimate) |
| Impact | About 15 papers written to date. |
| Start Year | 2016 |
