From Wikipedia, the free encyclopedia
Roberto Abraham (b. 1965, Manila, Philippines) is a Canadian astronomer and is Professor of Astronomy at the University of Toronto and a E.W.R. Steacie Fellow. Educated at UBC (BSc) and Oxford (DPhil), Abraham did post-doctoral work at at the Dominion Astrophysical Observatory, the Institute of Astronomy, Cambridge and the Royal Greenwich Observatory.
Abraham is best known for his work on high-redshift galaxy morphology, in particular for his invention of the Concentration-Asymmetry morphological classifier, a widely adopted automated method for the classification of galaxies. This method was originally applied to data from the Hubble Space Telescope, especially the Hubble Deep Field and variants of the technique have been applied in many Hubble imaging campaigns.
In addition to his work on galaxy morphology Abraham is also well known for his work with the Gemini telescopes. He was co-principal investigator of the Gemini Deep Deep Survey (GDDS) an observational campaign (2003–2003) using the Gemini Observatory to study massive galaxies in the early Universe. He is leading the "Gemini Genesis Survey" which aims to find the first galaxies in the very early universe prior to the era of cosmic reionization.
