League Table of z > 5.7 quasars

League Table of z > 7.0 Lyman-alpha emitters


I am currently a postdoctoral researcher at the University College London (UCL) in the group of Prof. Richard Ellis. Previously, I spent 7 years at the University of Cambridge getting a BA and MA in Natural Sciences, an MSci in Astrophysics, and a PhD at the Institute of Astronomy, Cambridge, UK. Prof. George Becker (UC Riverside) and Prof. Martin Haehnelt (IoA) were my supervisors.

My research interests span the time period of the history of the Universe known as the Cosmic Dawn, during which the first stars and newly assembled first galaxies are breaking down the neutral Hydrogen in their surroundings - becoming possible to observe for the first time.

High redshift quasars are a tool of choice for probing this era due to their great intrinsic brightness and straightforward intrinsic emission spectra. My work uses these object for many things from probing the neutral fraction of hydrogen at z=7, to constraining early metal enrichment, galaxy formation processes, and the topology of reionisation.

Research TL;DR

I learn about the early Universe by using quasar spectra. I've used quasar spectra from many different sources, taken my own spectra at the Keck telescope, Hawaii, and also used simulations of quasar spectra. There are many ways to use them which tell us various things about our Universe when it was young. Quasars spectra are the best.
