Dark Energy Spectroscopic Instrument (DESI)
The Dark Energy Spectroscopic Instrument (DESI) consortium is conducting a five-year survey to map the large-scale structure of the Universe over one-third of the sky and 11 billion years of cosmic history, aiming to study the physics of dark energy.
GMACS - Moderate Dispersion Optical Spectrograph for the Giant Magellan Telescope is a powerful optical spectrograph that will unlock the power of the Giant Magellan Telescope for research ranging from the formation of stars and planets to cosmology.
James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES)
JADES will use guaranteed time in James Webb Space Telescope (JWST) cycle 1 to produce infrared imaging and spectroscopy of unprecedented depth in the two premier extragalactic deep fields, GOODS-South (CDF-S) and GOODS-North (HDF). These data will reveal the early phases of galaxy formation, probing the rest-frame optical spectroscopy and morphology of galaxies from redshifts 2-3 out to z>10. JADES expects to collect data on about 100,000 galaxies, adding to the extensive legacy of these well-studied fields.
Sensing the Dynamic Universe
The Sensing the Dynamic Universe (SDU) project creates sonified videos exploring the multitude of celestial variables such as stars, supernovae, quasars, gamma ray bursts and more. We sonify lightcurves and spectra, making the astrophysics of variables and transients accessible to the general public, with particular attention to accessibility for those with visual and/or neurological differences.
Sloan Digital Sky Survey (SDSS)
The Sloan Digital Sky Survey continues its twenty-year legacy of wide-field optical/infrared imaging and spectroscopy, which has led astronomy into the era of large archives and data science. Harvard and Smithsonian are both full institutional members of the latest epoch of the survey, SDSS-V, which started observations in 2020.
The Star Formation Reference Survey
Astronomers study star formation as a way of understanding our own origins, as well as the structure of galaxies and the evolution of the cosmos as a whole. However, the farther back in time, astronomers often rely on a single measurement type for each galaxy to measure star-formation rates. The Star Formation Reference Survey (SFRS) is designed to improve and assess the reliability of all of these measurements by cataloging nearby star formation, using NASA’s Spitzer Infrared Space Telescope and other observatories. The data produced provides a useful reference data across a wide range of wavelengths in the spectrum of light, which can be applied across surveys of star formation in close-by and distant galaxies. The SFRS observational effort is led by astronomers at the Center for Astrophysics | Harvard & Smithsonian, in collaboration with other researchers around the world.
