Ashley Chrimes

I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick. My supervisor is Elizabeth Stanway.


My research looks at the environments and progenitors of extragalactic transients, in particular gamma-ray bursts (GRBs) - the most luminous electromagnetic events in the Universe. By studying the host galaxies where these explosions occur, we learn about the stellar populations and conditions which are capable of producing them. GRBs show great variety in terms of their duration, lightcurves, isotropic energy and spectral shapes (manifesting as short, long, ultra long, low luminosity, dark bursts and more). The study of GRB environments continues to prove invaluable in determining the origin of this variety. I am now working on identifying progenitor pathways of supernovae and GRBs in BPASS (, and exploring the consequences of matching BPASS rate predictions to observations.

Teaching & Outreach

I have taught first year undergraduates in the core physics laboratory, and the first year electronics labs, for the past 3 years.

I am also involved in a number of outreach activities, including planetarium events at the University and local schools, departmental open days at the University, and in 2016, I participated in a Christmas public lecture at Warwick Arts Centre - where I played the part of a neutron star!

Start date: Oct 2016, STFC Grant Code: 1763016
