Quenching of Star Formation
Vivienne Wild, Tamas Budavari, Jeremy Blaizot +5
In the last decade we have seen an enormous increase in the size and quality of spectroscopic galaxy surveys, both at low and high redshift. New statistical techniques to analyse l…
The environments of starburst and post-starburst galaxies at z=0.4-0.8
Bianca M. Poggianti, Alfonso Aragon-Salamanca, Dennis Zaritsky +16
Post-starburst (E+A or k+a) spectra, characterized by their exceptionally strong Balmer lines in absorption and the lack of emission lines, belong to galaxies in which the star for…
The Galaxy and its stellar halo - insights from a hybrid cosmological approach
Gabriella De Lucia, Amina Helmi
We use a series of high-resolution N-body simulations of a `Milky-Way' halo, coupled to semi-analytic techniques, to study the formation of our own Galaxy and of its stellar halo.…
The relation between star formation, morphology and local density in high redshift clusters and groups
Bianca M. Poggianti, Vandana Desai, Rose Finn +17
We investigate how the [OII] properties and the morphologies of galaxies in clusters and groups at z=0.4-0.8 depend on projected local galaxy density, and compare with the field at…
