The nature of the ISM in galaxies during the star-formation activity peak of the Universe
G. Popping, J. P. Pérez-Beaupuits, M. Spaans +2
We combine a semi-analytic model of galaxy formation, tracking atomic and molecular phases of cold gas, with a three-dimensional radiative-transfer and line tracing code to study t…
Evolution of the atomic and molecular gas content of galaxies
Gergo Popping, Rachel S. Somerville, Scott C. Trager
We study the evolution of atomic and molecular gas in galaxies in semi-analytic models of galaxy formation that include new modeling of the partitioning of cold gas in galactic dis…
Damped Lyα Absorption Systems in Semi-Analytic Models with Multiphase Gas
Michael Berry, Rachel S. Somerville, Marcel R. Haas +4
We investigate the properties of damped Lyα absorption systems (DLAs) in semi-analytic models of galaxy formation, including partitioning of cold gas in galactic discs into atomic,…
A low-mass cut-off near the hydrogen burning limit for Salpeter-like initial mass functions in early-type galaxies
Matteo Barnabè, Chiara Spiniello, Léon V. E. Koopmans +3
We conduct a detailed investigation of the properties of the stellar initial mass function (IMF) in two massive early-type lens galaxies with velocity dispersions of sigma ~245 km/…
The stellar IMF determined in early-type galaxies from a non-degenerate set of optical line indices
Chiara Spiniello, Scott Trager, Léon V. E. Koopmans +1
We investigate the optical spectral region of spectra of 1000 stars searching for IMF-sensitive features to constrain the low-mass end of the initial mass function (IMF) slope in e…
The temperatures of Red Supergiants
Ben Davies, Rolf-Peter Kudritzki, Bertrand Plez +6
We present a re-appraisal of the temperatures of Red Supergiants (RSGs) using their optical and near-infrared spectral energy distributions (SEDs). We have obtained data of a sampl…
