Major Activities/Achievements

1. Awarded 2016 American Astronomical Society Lancelot M. Berkeley New York Community Trust Prize for work on The most-distant galaxies viewed with Hubble. Plenary Talk at January 2017 AAS 229 on Exploring for Galaxies in the First Billion Years with Hubble and Spitzer — Pathfinding for JWST
2. Science 1: Garth’s early work was on globular clusters and nearby ellipticals, but then with the advent of the powerful instruments on Hubble he transitioned to working on distant galaxies. Major ongoing programs on galaxy formation and evolution at high redshift from z ~ 2 ~ 10; recent work on galaxy build-up in the reionization epoch – during the first Gyr. Large number of highly-cited publications with focused team. Extensive Hubble Space Telescope (HST), Spitzer, and Keck observing time and collaborations. PI of HUDF09 HST WFC3/IR program—top-ranked and largest program awarded by Cycle 17 HST TAC. Team has led the way on the very highest redshift galaxy discoveries, the latest being at redshift z~11.1, just 400 million years after the Big Bang. Our latest results on the sizes of distant galaxies and on the star formation rate density at z~10, combined with the latest Planck results that indicate that reionization began around redshift z~10, have significant implications for the detectability of the "first galaxies" with JWST.
3. Science 2: The publications from this research on the most distant and earliest galaxies, with an international team of scientists, have consistently been among the most highly cited papers on galaxies in the early universe. PI of eXtreme Deep Field (XDF) and Hubble Legacy Fields (HLF). XDF combines 10 years of HST ACS and WFC3/IR data in the deepest field ever (to 31 mag 5σ). HLF-GOODS-S combines 2500 orbits of data on GOODS-S/CDF-S region. Numerous science talks at international workshops on galaxy evolution in the first 1–2 Gyr. Organized high redshift galaxy workshops. Lead organizer of 2008 and 2016 Aspen Physics “Reionization” workshops. Many press releases and interviews on new results with outstanding international visibility (last release: 116 articles with >600 million potential readers!). Highly-visited firstgalaxies.org website top-rated in searches on early galaxies. More information on projects and papers on Garth’s home page.
4. NGST/JWST: Leader of the early work in 1987-1992 on the Next Generation Space Telescope (NGST). NGST is now known as the James Webb Space Telescope (JWST). He was one of original initiators, with Peter Stockman and Pierre Bely, of a large 8-m class passively cooled IR space telescope and organized the first science conference on NGST in 1989. He chaired the “UV-Optical in Space Panel” of the 1990 Decadal Survey that recommended a 6-m passively-cooled large space telescope, and continued work on the concept with NASA HQ and JPL support into the early 1990s. This work ultimately became the NGST recommended in the 2000 Decadal, and then renamed to JWST. A STScI Newsletter article in June 2016 gave an overview of the early history.
5. AAAC: Chair, Congressionally chartered Astronomy and Astrophysics Advisory Committee (AAAC) from 2004 to 2008. AAAC is FACA committee whose annual report is to NSF, NASA and DOE, to Congress and to OMB/OSTP. Annual reporting to agency (NSF, NASA, DOE) senior management, OSTP Director and Congressional staff. Five major studies set up while GDI was AAAC Chair: Task Force on Cosmic Microwave Background Research (TFCR) 2005; Report on GSMT-JWST Synergy 2005; Dark Energy Task Force (DETF) 2006; Dark Matter Scientific Assessment Group (DMSAG) 2007; ExoPlanet Task Force (ExoPTF) 2008.

7. Co-Chair of Center Directors External Team (CDET) that is assessing progress on the JWST mission since 2015.
8. JSTAC: Chair, 2009–, James Webb Space Telescope Science Advisory Committee (JSTAC). JSTAC is charged with advising STScI on maximizing the science return from JWST. Numerous letters regarding recommendations can be found at this link.

10. HST ACS: Deputy PI, HST Advanced Camera for Surveys (ACS): Worked closely with PI Holland Ford towards the successful completion and launch of the most powerful optical imager on HST. Improved HST’s performance by 10X.
11. NHST/VLST: Co-organizer, 2002 with Rob Kennicutt of major workshop (“Hubble’s Science Legacy”) sponsored by NASA, ESA, AURA and U.
