My research interests span a wide range of topics and I work on a variety of projects. Click on the topics below to learn more about my current main projects.
The ALPINE survey is a 70-hour large program carried out with the Atacama Large Millimeter Array to obtain sub-millimeter measurements for the largest sample of galaxies in the early Universe. The goal of this survey is to study formation and evolution of these galaxies by analysing their gas and dust properties. I am the lead US principal investigator of ALPINE.
COSMOS-Web is a 255 hour treasury program to be conducted by the James Webb Space Telescope (JWST) in cycle 1. It observes a contiguous 0.54 deg2 area in four filters with NIRCam imaging and, in parallel, a total area of 0.19 deg2 of MIRI imaging in one filter. COSMOS-Web will advance our understanding of the properties and clustering of very high redshift galaxies (z=6-12) in the Epoch of Reionization, the earliest quiescent galaxies, the relation between stellar mass and Dark Matter halo mass, and many other science topic.
The Joint Survey Processing (JSP) project is an IPAC-led initiative with the goal to optimally combine future LSST, Euclid, and WFIRST survey datasets at the pixel level and to provide an interface to the community to use these high-quality data products. Within JSP we work on defining, creating, and implementing tools to combine data at space and ground-based resolution at the pixel level and at different wavelengths.
SPHEREx is a NASA Medium Explorer mission (launch 2024) aiming at constraining the physics of inflation, tracing the history of galactic light production through a deep multi-band measurement of large-scale clustering, and investigating the abundance and composition of water and biogenic ices in the early phases of star and planetary disk formation. SPHEREx will obtain near-infrared 0.75-5.0μm spectra in 6 arc-second pixels for the entire sky.
The Cosmic Dawn Survey is a 50 square degree multi-wavelength survey of the Euclid Deep and Calibration fields. The scientific aim is to understand the co-evolution of galaxies, black holes, and the dark matter haloes that host them across cosmic time. The survey parameters are designed to enable stellar mass measurement, to probe the large scale structure of reionization in the early Universe, and to find luminous quasars to the highest redshifts where they exist.
The Cosmological Advanced Survey Telescope for Optical and uv Research (CASTOR) is a 1-meter space telescope mission proposed and led by the Canadian Space Agency (CSA) with the aim to image the skies at ultraviolet (UV) and blue-optical wavelengths at a resolution similar to the Hubble Space Telescope. The science enable by that mission covers topics from Exoplanets to Cosmogoly. I am part of the Galaxies and Cosmic Star Formation working ground for CASTOR.
