Stellar populations, Galaxy Evolution and Instrumentation


Prof.dr. Scott Trager, Kapteyn Astronomical Institute, Rijksuniversiteit Groningen

I'm a Professor at the Kapteyn Astronomical Institute at the Rijksuniversiteit Groningen.

My research focuses on understanding the formation and evolution of the most massive galaxies in the Universe: elliptical and lenticular early-type galaxies. Recent work includes

  1. -the next-generation stellar spectral library for stellar population modeling: XSL

  2. -determination of the slope of the initial mass function in early-type galaxies using stellar population analysis and gravitational lensing

  3. -the neutral and molecular gas content of star-forming galaxies back to z=3.0

  4. -the deepest-ever color-magnitude diagram of M32, the compact elliptical companion of M31 (the Andromeda Galaxy) and the first determination of its star-formation history from resolved stars, as well as studies of its ancient metal-poor variable star population

  5. -models of the chemical enrichment and star-formation histories of early-type galaxies

  6. -the stellar populations of early-type galaxies seen in the near-infrared

  7. -the neutral gas properties of nearby early-type galaxies

I also help design and build front-line astronomical instruments.

  1. -I'm the Deputy PI, Dutch PI, and Project Scientist for WEAVE, a massively-multiplexed spectrographic survey facility for the WHT at the ING on La Palma in the Spanish Canary Islands.
