Research Projects

DES

The Dark Energy Survey (DES) is an optical-NIR imaging survey that uses a 570-Megapixel camera on the 4-meter Blanco Telescope in Chile to cover 5000 deg2 of the southern sky. The primary science goal of DES is to understand the accelerating expansion of the universe through combined measurements of supernova, large-scale stucture, weak lensing, and galaxy clusters. The rich dataset from DES also enables studies of dark matter, galaxy evolution, and transient science.

LSST

The Legacy Survey of Space and Time (LSST) is a next-generation optical-NIR imaging survey on the Vera C. Rubin Observatory at Cerro Pachon in Chile. LSST will use a 3.2-Gigapixel camera and an 8.4-meter primary mirror to cover ~18,000 deg2 of sky. Over its 10 year mission, LSST will produce a "movie" of the universe by imaging the entire visible sky every 3 nights. The LSST Dark Energy Science Collaboration (DESC) hosts the study of dark energy with LSST.

SPT

The South Pole Telescope (SPT) is a 10-meter telescope operating at the geographical South Pole, designed to measure the temperature and polarization of the cosmic microwave background (CMB) at mm/submm wavelengths. The high angular resolution and low noise level of SPT allows unprecedented measurements of CMB lensing and galaxy clusters. SPT and DES observe the same area of sky, which enables joint analyses of the two data sets.

CCD Development

Silicon charged-coupled devices (CCDs) have been the primary detector for astronomical observations for the last 30 years. While CCD technology is mature, it is far from stagnant. We work at the interface of hardware and software to improve the performance of these detectors for applications in future cosmic surveys.

Deep Skies

Deep Skies brings together experts in astronomy and artificial intelligence to explore the mutual benefits of large-scale data analysis for both fields. The Deep Skies team is specifically interested in the advent of advanced algorithms for data-intensive research in astrophysics and cosmology.


DELVE

The DECam Local Volume Exploration (DELVE) Survey is a 3-year, 126-night survey of the entire southern sky. DELVE uses observations of the smallest and faintest galaxies to understand the mechanisms governing galaxy formation and the fundamental physics of dark matter.
