Together with Rijksmuseum Boerhaave, the Lorentz Center organizes the public event ‘Exploring the Ghostly Side of Galaxies with Dragonfly

Bigger telescopes are usually better telescopes…. but not always. In this talk professor Abraham will explore the ghostly world of large structures at the sky, such as galactic stellar halos, low-surface brightness dwarf galaxies, and other exotica such as supernova light echoes. These objects are nearly undetectable with conventional telescopes, but their properties may hold the key to understanding how galaxies assemble. Professor Abrahams will describe why finding these objects is important, and why it is so devilishly difficult.

Speaker Roberto Abraham is a professor in the Department of Astronomy and Astrophysics at the University of Toronto. His work is focused on observations of galaxy formation and evolution and the development of innovative instruments, such as the Dragonfly Telephoto Array, now the world’s largest all-refracting telescope.

This public lecture is part of the workshop 'The Bewildering Nature of Ultra-diffuse Galaxies',  which takes place from 13 through 17 August 2018 at the Lorentz Center.
