Karl GlazebrookFAA (born 1965) is a Britishastronomer, known for his work ongalaxy formation, for playing a key role in developing the "nod and shuffle" technique for doingredshift surveys with large telescopes, and for originating thePerl Data Language (PDL).[1]
Glazebrook was born in 1965 in theUnited Kingdom, and educated at theUniversity of Cambridge and theUniversity of Edinburgh (PhD 1992). He held post-doctoral appointments at theUniversity of Durham andUniversity of Cambridge before moving to theAnglo-Australian Observatory, where he played a central role in supporting the2dF galaxy survey as its instrument scientist. He moved toJohns Hopkins University in 2000 where he was Professor of Astronomy until 2006, at which time he became Professor of Astronomy atSwinburne University of Technology in Melbourne, Australia.[2] His work has been cited over 40,000 times in the literature of astronomy.
Glazebrook also developed the open-sourcePerl Data Language, a perl-based alternative to the commercialIDL.
Glazebrook was one of the leaders of theGemini Deep Deep Survey (GDDS) which measured the evolution of galaxies usingGemini Observatory and theHubble andSpitzer Space Telescopes.[3] The project, along with a number of other studies, determined in 2004 that massive galaxies formed surprisingly early in the distant Universe, explaining why a lot of them appear so remarkably old.[4] As a whimsical side-project Glazebrook also determined that the bulk-averaged color of the Universe iscosmic latte. Both pieces of work received wide publicity in the international press. The bulk-averaged color earned some additional international publicity because a software bug had initially suggested a pale turquoise instead of the bland beige.[5] He is also well known in the astronomical community for his pioneering work in developing the baryon oscillation technique to use the distribution of galaxies as a probe ofdark energy.
After his move to Australia he played a leading role in theWiggleZ Dark Energy Survey between 2006 and 2011.[6]
