Characterizing Galaxies with Spectroscopy with a view for JWST
Galaxies 800 million years after the Big Bang seen with the Atacama Large Millimetre Array
Speaker - Renske Smit (Cambridge)
Renske is an astronomer and postdoctoral fellow at the University of Cambridge in the UK, supported by a NWO Rubicon grant. Her research is focused on observations of galaxies in the very distant Universe, using telescopes such as the Hubble Space Telescope, the Spitzer Space Telescope and the Very Large Telescope of the European Southern Observatory in Chile. She is one of the participants of the workshop “Characterizing Galaxies with Spectroscopy with a view for JWST” that is being held in the Lorentz Center from 23 Oct 2017 through 27 Oct 2017.
The identification of galaxies in the first billion years after the Big Bang presents a challenge for even the largest optical telescopes. When the Atacama Large Millimetre Array (ALMA) started science operations in 2011 it presented a tantalising opportunity to identify and characterise these first sources of light in a new window of the electromagnetic spectrum. While scientists have struggled in the past few years to obtain strong sub-millimetre signals from galaxies in the earliest epoch of cosmic time, we have recently successfully identified new sources in this epoch using ALMA. Moreover, we study the gas kinematics of these distant sources for the first time and find that these galaxies likely already form rotating disks, such as seen in the star-forming galaxies much later in the Universe.
