RESEARCH
I seek to understand how galaxies formed and evolved when the Universe was only a fraction of its present age. My research is focused through three key projects:
(1)The massive, 200-hour JWST Guaranteed Time Observations CANUCS program that will let us investigate in detail the inner workings of thousands of low-mass galaxies at Cosmic Noon (z~2) and Cosmic Dawn (z>6). Following the successful JWST launch on 25 December 2021, we obtained the first batch of our CANUCS data in October 2022!
(2)The 68-night CFHT CLAUDS survey that together with affiliated deep surveys from other telescopes lets us use several million galaxies over a wide redshift range to do enormously large statistical studies of the processes that drive galaxy evolution. CLAUDS is now joined by its newer sibling, DEUS, which aims to cover 10 sq degrees in the Euclid Deep Field North and study how galaxy properties relate to their location within the high-redshift Cosmic Web.
(3)The GIRMOS AO-fed, multi-IFU spectrograph now under construction by a partnership of Canadian institutions, including our team at Saint Mary’s. GIRMOS will let us do detailed, spatially-resolved studies of 100’s of distant galaxies when commissioned at Gemini-North later this decade.
NEWS
2023 February 1: CLAUDS public data release, catalog paper, and new website, all at once!
I am so excited by the amazing amount of very cool science that has already relied on CLAUDS data (22 papers as of today, with more submitted and in prep!), and the science still to come with the data in the hands of the community. And, now underway, the DEEP project with which, together with partners, we are building a contiguous 10 square-degree, multi-wavelength dataset in Euclid’s Northern Deep Field.
