SuperCLASS Survey

SuperCLASS is a deep, wide-area survey originally designed to detect the effects of weak lensing in radio continuum in a supercluster region. We look to repurpose it to obtain internal ~kpc maps of micro-Jansky radio sources around the peak of cosmic star formation (z~2) and determine their evolutionary origins through morphological analysis.

What is e-MERLIN?

The enhanced Multi-Element Remotely Linked Interferometer Network is a network of seven UK-based radio telescopes headwquartered at Jodrell Bank Observatory. The facility’s unique combination of sensitivity and spatial resolution makes it a great tool for tracing spatially resolved star formation in heavily obscured galaxies.

The SuperCLASS Photometric Redshift Catalog

The first step in our analysis of galaxies discovered in the SuperCLASS Survey was determining their distances, a.k.a. their redshifts. Without spectroscopic observations in hand, I was tasked with creating a photometric redshift catalog for the entire field consisting of roughly ~200,000 galaxies. This was my first project as a graduate student and resulted in my first first-author publication.
