UCL Astrophysics Group



The Astrophysics Group of UCL's Department of Physics & Astronomy is one of the largest in the UK. Our research areas cover massive stars, star formation, interstellar and circumstellar processes, astrochemistry, cosmology, galaxy formation and evolution, extra-solar planets, atmospheric physics and instrumentation. Our main research topics are listed below.

Research Fellowships - We are keen to support a limited number of strong candidates in applying for Research Fellowships. Find out more about applying for fellowships here.

Extragalactic Astrophysics

Our research includes star formation in our own and other galaxies, the astrophysics of gas and dust in nebular and circumstellar environments and studies of the properties of massive and evolved stars.

Galactic Astrophysics

Our research includes studies of the dynamical, stellar and star formation properties of low- intermediate- and high-mass galaxies over a wide range of redshifts.
