We work together to unlock the secrets of the universe! ;)

Raymond works on observations of galaxy kinematics using Keck and Hubble, and has most recently been working on numerical simulations of galaxies. He found the "Mass of Disk Formation" in the local universe, above which all star-forming galaxies are disks. Raymond led the SIGMA survey of galaxy kinematics at a redshift of 2 using the MOSFIRE spectrograph on Keck and found that a redshift of 2 is the "Epoch of Disk Assembly." Now Raymond is performing mock observations of galaxy simulations (using the VELA and FIRE suites) to help interpret current and future (JWST/EELT) observations of galaxy kinematics and morphologies.
Dr. Camilla Pacifici
Postdoc, Soon to be NIRISS Team member at STScI
Camilla is an expert on spectral energy distribution modeling of galaxies. She has created models which take into account low to high resolution spectra of galaxies (emission lines, absorption lines, continua), complex star-formation histories motivated by the hierarchical universe, and more sophisticated dust models. Her approach to fitting data is fully Bayesian. Camilla's recent results on the star-formation histories of quiescent galaxies strongly suggest two separate quenching mechanisms for low and high mass galaxies.
Dr. Gregory Snyder
Giacconi Fellw at STScI, Soon to be Archive Scientist
Gregory is a leader in the field of using mock observations of numerical simulations of galaxies to inform how we interpret observations, and in particular Hubble observations. Here is a public lecture he gave on studying virtual universes with supercomputer simulations.
