معرفی
Roberto Abraham is a Professor and Chair of the David A. Dunlap Department of Astronomy and Astrophysics at the University of Toronto, affiliated with the Faculty of Arts and Science. He holds a PhD from the University of Oxford (1992) and has conducted postdoctoral research at the National Research Council of Canada and Cambridge University. His research focuses on galaxy evolution, observational cosmology, and developing novel instruments like the Dragonfly Telephoto Array. He has led projects such as the Gemini Deep Deep Survey (GDDS), discovering high-redshift galaxies and pioneering automated galaxy classification systems (e.g., CAS and Gini-M20 parameters).
Abraham has received prestigious awards including the Jackson-Gwilt Medal (Royal Astronomical Society), P. G. Martin Award, and Killam Research Fellowship. He has served on advisory boards for NASA’s James Webb Space Telescope and international observatories. His work combines observational astronomy with instrument innovation, addressing questions about galaxy morphology, dark matter content, and low-surface-brightness phenomena. He actively engages in public outreach, serving as Honorary President of the Royal Astronomical Society of Canada’s Toronto Centre.
Abraham’s research group uses the Dragonfly Array to study ultra-diffuse galaxies and their dark matter properties, as well as leveraging JWST and Keck observations. His grants include funding from the Canada Foundation for Innovation for expanding the Dragonfly Spectral Line Mapper. He advises graduate students exploring galaxy evolution, instrument design, and computational astronomy techniques.
