Professor of Astrophysics

About

I am a professor of Astrophysics in the Department of Physics & Astronomy at University College London (UCL).

My research programme is centered around the question of what regulates the growth and evolution of galaxies. In particular, I use radio telescope to make a census of the cold gas contents of large sample of galaxies; understanding when, where and how galaxies efficiently form stars out of gas is key in identifying the mechanism driving their evolution.

Recent highlights

Publication highlights

04.2022 In a follow up to last year's paper, PhD student Lucy Hogarth used kinematic evidence to show how disc instabilities (especially bars) may be link with large scale ionised gas outflows. Read the new paper here.
02.2022 New article for Annual Reviews of Astronomy & Astrophysics, about the cold interstellar medium of galaxies in the local universe, setting its importance in the galaxy evolution context. Preprint now available.
02.2021 We released a new and accurate determination of the abundance of cold gas at z~0 and present the xCOLD GASS-derived molecular gas mass function, in a paper by recent graduate Tom Fletcher.

JINGLE data release

10.09.2018 JINGLE is a legacy survey at the JCMT, targeing dust and gas across the local galaxy population. The strategy, goals, and sample of the survey are described in Saintonge et al. (2018), which also includes the public data release of our value-added UV-to-FIR photometric catalog. The data products are available through the JINGLE website
