Galaxy formation and evolution is one of the key questions in contemporary astrophysics. The main goal of my research is to provide strong observational constraints for models of galaxy formation and evolution. In particular I am interested in how a spiral galaxy forms. The empirical test bed for models of spiral galaxies can be provided in two distinctly different ways: Either by studying large samples of spiral galaxies at varying redshifts (i.e. different ages) or by studying our own galaxy, the Milky Way, in great detail. What is sometime called Near Field Cosmology.
The Milky Way is unique in that we can study its stellar and gas contents in much greater detail than in any other galaxy. I have therefore chosen to focus on the Milky Way to provide the necessary observational evidence to test today's models of galaxy formation and evolution.
I am in particular interested in understanding the Milky Way as a galaxy with a special focus on understanding the origin of the stellar component referred to as the thick disk. I am currently engaged in the following survey work:
4MOST is the next generation wide-field spectrograph for surveys at ESO. The five year survey will yield more than 10 million medium resolution spectra of stars across all stellar populations in the Southern Hemisphere as well as more than 3 million high-resolution spectra for stars in the disk and Galactic bulge. Learn more about 4MOST by reading our webpages. If you are interested to join please contact us.
WEAVE is an instrument, a survey, and a collaboration which will provide more than 4 million stellar spectra in the Northern Hemisphere.
This was a large European collaboration lead by Gerry Gilmore and Sofia Randich. The survey has been completed and has carried out 300 nights of observations in visitor mode with the FLAMES spectrograph on VLT. You find all Gaia-ESO publications on ADS .
