Copenhagen Astrophysics Seminars (CAS) - Gabriel Brammer - Why wait? Wide-area Imaging & Spectroscopy Surveys for Galaxy Evolution with the Hubble Space Telescope
The Copenhagen Astrophysics Seminars will be a weekly seminar series which will be held every Monday in room 129 at DAWN-DTU. This week it will be held by DAWN's own Gabriel Brammer. The series will generally be hosted by Xue - Jian.
The title of this Monday's talk is: Why wait? Wide-area Imaging & Spectroscopy Surveys for Galaxy Evolution with the Hubble Space Telescope:
Abstract: Over the next decade, the Euclid and WFIRST space missions will open a new frontier for studies of galaxy evolution with deep near-infrared surveys that cover a significant fraction of the visible sky. By contrast, many of the recent discoveries in this field have come from deep observations with the Hubble Space telescope over "pencil-beam" areas many of orders of magnitudes smaller. However, considering the entirety its archival data holdings, Hubble has already observed more than 3 square degrees in the near-infrared with WFC3 imaging and more than 1.5 square degrees with slitless grism spectroscopy. Together these observations today can probe populations of relatively rare objects that are key signposts for understanding how galaxies form and evolve, such as the most massive, evolved galaxies at intermediate redshifts and the most luminous galaxies at the epoch of cosmic dawn only a short time after the Big Bang
