Patrick McCarthy


Patrick McCarthy is the former Vice President of the Giant Magellan Telescope Organization and an Astronomer at the Carnegie Institution for Science. McCarthy is a world-recognized astronomical leader; his seminal work on galaxy evolution and the high-redshift universe has earned him wide scientific respect and recognition. He has spent more than thirty years working with the NOIRLab facilities, as a frequent observer and as a member of advisory and oversight committees. McCarthy’s experience of large projects, including developing instruments for Hubble and his leadership roles in the Giant Magellan Telescope Project, will be invaluable as NOIRLab charts its path through the coming decade and beyond.

Tom Matheson

Community Science and Data Center Interim Director

Tom Matheson joined the National Optical Astronomy Observatory in 2004 as a staff astronomer in the U.S. National Gemini Office. Since 2017, he has been the Head of Time-Domain Services in the Community Science and Data Center, where he is the PI of the ANTARES time-domain event broker. Matheson received his PhD from the University of California at Berkeley in 2000, with his thesis topic being spectroscopy of stripped-envelope supernovae. This was followed by a post-doctoral position at the Harvard-Smithsonian Center for Astrophysics. His research interests continue to focus on explosive astronomical events like supernovae and gamma-ray bursts, with forays into other areas of time-domain science, cosmology, and methods for calibration.
