1. Formation and evolution of galaxies

  2. Formation of stars over cosmic time

  3. Photo-z and SED-fitting techniques

I study the formation and evolution of galaxies at epochs when the Universe was only a fraction of its present age. I am particularly interested in where and when the Universe made its stars and the complex chemical elements that we are all made of. In my work I use space-based facilities including the Hubble and Spitzer Space Telescopes, as well as ground-based ones such as the Keck, Gemini, and Magellan observatories in Hawaii and Chile. And after a long wait but quite soon now, I look forward to using the James Webb Space Telescope in this research!

Jean Coupon visit

Jean Coupon, a friend and collaborator on the CLAUDS project, visits us from Geneva Observatory for the week of Nov 20-25.  In addition to giving a fascinating colloquium on Probing the Galaxy-Mass Connection in TeraByte-scale Imaging Surveys (link here), Jean spends his time in Halifax discussing ongoing science and thinking up new projects with our group members.  A great visit, all-around!

GIRMOS funded

Canada Foundation for Innovation today announced funding to build, over the next five years, the Gemini InfraRed Multi-Object Spectrograph (GIRMOS).  See SMU’s press release here.

GIRMOS is an instrument for Gemini that will use adaptive optics and multiple intergral-field spectroscopy units to study the detailed working of galaxies in the distant universe.

SMU’s part in the project is to develop the data simulator and data reduction pipeline... and, of course, we also plan to use it for observing distant galaxies once GIRMOS is on the telescope in 2023 or so.
