LIGO: Laser Interferometer Gravitational Wave Observatory

Members of the Center play important roles in the Laser Interferometer Gravitational-wave Observatory (LIGO) Collaboration, an ambitious project to detect and study gravitational waves from astrophysical objects such as black holes and supernovae. UW-Milwaukee hosts a state of the art data center specifically designed and constructed for the analysis of data from LIGO and other astronomical observatories.

ZTF: Zwicky Transient Facility

The CGCA is a founding partner in the Zwicky Transient Facility, a new optical sky survey designed to find everything from asteroids to distant supernovae.

NANOGrav: North American Nanohertz Observatory for Gravitational Waves

The CGCA is part of the North American Nanohertz Observatory for Gravitational Waves, a pulsar timing array working to detect low-frequency gravitational waves with a galaxy-scale detector.

Observatories: Across the electromagnetic spectrum

Members of the CGCA are part of new radio telescopes such as the Murchison Widefield Array (MWA) and the Australian Square Kilometre Array Pathfinder (ASKAP), both located in remote Western Australia. CGCA members also conduct observations with the world's leading optical observatories, including the Hubble Space Telescope and Keck Observatory.

MKE-UO: Milwaukee Urban Observatory

The CGCA is home to the Milwaukee Urban Observatory, where together with members of the Geography and Architecture departments we apply the techniques of astronomical imaging and analysis to the distribution of light in the city.
