Two PhD Fellowship Positions in Extragalactic Astronomy at the Cosmic Dawn Center, National Space Institute of Denmark

Project descriptions
Fellowships are intended for outstanding candidates with a background in astronomy, physics, or
The first fellowship is intended to work on numerical simulations of the first galaxies as they formed and evolved during the cosmic dawn epoch.  One of the goals is to simulate the on-sky large-scale fluctuations in the line intensities of the first galaxies. Observing these fluctuations is called intensity mapping (IM), and is a new technique for studying the large-scale structure of the Universe. The IM signal depends both on the detailed astrophysical processes in the ISM within the galaxies as well as the underlying dark matter density.  The IM technique, therefore, provides important cosmological and astrophysical information, not readily obtained using other methods.

The second fellowship will mainly, but not exclusively, work on observational data of high-redshift galaxies and galaxy protoclusters. Part of the project will study distant galaxy protoclusters, the largest gravitationally bound objects in the Universe, and characterize their galaxy populations using multi-wavelength data obtained as part of the COSMOS survey, the RAGERS survey, the SPT survey, and the GLT+GISMO Extragalactic Survey. Numerical simulations of protoclusters will be undertaken in synergy with the observations to gain physical insight into their formation and evolution with cosmic time.
