Galaxy Evolution and Cosmology Initiative (GECO)

GECO Title ArtMilky Way Analog Image with gas and shocks

Galaxy Evolution and Cosmology (GECO) is a research initiative focused on galaxy evolution and cosmology made possible by generous seed funding from the Provost and Dean’s office at UVa. The relevant themes include resolved stellar populations, near-field cosmology, the dark universe, and galaxy formation and evolution, from both theoretical and observational perspectives. UVA is a member of the LSST-Discovery alliance, SDSS, and has access to a range of telescope apertures and wavelengths (including LBT, MMT/Magellan). The UVA astronomy faculty have strong research ties to the scientific staff at the National Radio Astronomy Observatory (NRAO), which is located on the grounds of the University.
