Research Collaborations
C3VO Survey
The Charting Cluster Construction with VUDS and ORELSE (C3VO) survey maps five of the most massive cosmic structures in the early universe (z ~ 2–5). Combining deep spectroscopy from Keck Observatory (DEIMOS and MOSFIRE) with multi-wavelength imaging, C3VO's primary goals are to map cosmic structure growth over 12 billion years, track how galaxy properties change across different cosmic environments, and identify detection biases when finding early forming galaxy clusters.
GOGREEN Survey
Gemini Observations of Galaxies in Rich Early Environments (GOGREEN) is a premier spectroscopic survey that targeted 21 massive galaxy clusters and groups when the Universe was half its current age (z > 1). THe survey secured spectra for over 1,000 cluster galaxies with Gemini Observatory, GOGREEN's main goals are to discover how dense group and cluster environments shape galaxy growth, uncover why galaxy cluster environments shut down star formation, and provide a legacy dataset to test theories of cosmic structure formation.
GRACE Survey
Grism Reionization And Cosmic Evolution (GRACE) is an approved ultra-deep Wide Field Instrument (WFI) spectroscopic survey with NASA's Nancy Grace Roman Space Telescope, designed to construct an unprecedented 3D map of galaxies covering 1.5 square degrees in the Chandra Deep Field South. GRACE will bridge a vital gap in depth and sky coverage between JWST and wide-field surveys from Euclid and Roman. The survey itself is optimized to detect Lyman-alpha emitters (z = 7–10) to obtain definitive measurements of the epoch and pace of cosmic reionization. The survey will deliver ~290,000 emission-line redshifts to train photometric models for faint galaxies in the redshift desert, and will directly answer how galaxies influenced their cosmic environment and how environment shaped galaxy evolution across the first three-quarters of cosmic history.
