Extremely red galaxies: dust attenuation and classification
We re-address the classification criterion for extremely red galaxies (ERGs) of Pozzetti & Mannucci (2000 – PM00), which aims to separate, in the Ic − K (or Rc − K) vs. J−K colour–colour diagram, passively evolving, old (> 1 Gyr) stellar populations in a dust-free environment, associated with ellipticals (Es), from dusty starburst galaxies (DSGs), both at 1 < z < 2. We explore a category of obj...
متن کاملMerger History of Galaxies and Disk+Bulge Formation
We discuss the transitions of galaxy morphologies within the CDM paradigm under the assumption of bulge formation in mergers and disk growth via cooling of gas and subsequent star formation. Based on the relative importance of these two competing processes it is possible to make predictions on the expected morphological mix of galaxies. In particular we here discuss the generation of massive di...
متن کاملNearly Self-Consistent Disk-Bulge-Halo Models for Galaxies
We describe methods for setting up self-consistent disk-bulge-halo galaxy models. The bulge and halo distribution functions (df) are functions of E and Lz only. The halo’s flattening and rotation can be specified. The disk df is a function of E and Lz and a third “integral”, Ez, the vertical energy, which is approximately conserved in a warm disk with vertical extent. The models also have finit...
متن کاملNear-Infrared bulge-disk correlations of lenticular galaxies
We consider the luminosity and environmental dependence of structural parameters of lenticular galaxies in the near-infrared K band. Using a two-dimensional galaxy image decomposition technique, we extract bulge and disk structural parameters for a sample of 36 lenticular galaxies observed by us in the K band. By combining data from the literature for field and cluster lenticulars with our data...
متن کاملThe ultraviolet colours and dust attenuation of Lyman-break galaxies
Using GALFORM, a semi-analytical model of galaxy formation in the cold dark matter cosmology, we study the rest-frame ultraviolet (UV) colours of Lyman-break galaxies (LBGs) in the redshift range 2.5 ≤ z ≤ 10. As the impact of dust on UV luminosity can be dramatic, our model includes a self-consistent computation of dust attenuation based on a radiative transfer model. We find that intrinsicall...
