We present estimates of CN and Mg overabundances with respect to Fe for early-type galaxies in eight clusters over a range of richness and morphology. Spectra...

This paper addresses some questions which have arisen from the use of the Sérsic r1/n law in modelling the luminosity profiles of early-type galaxies. The first...

Within the classical Eulerian theory of gravitational instability, and in an Omega = 1 universe, we introduce a method for obtaining iterative solutions for the...

We present the star formation history (SFH) and its variations with galactocentric distance for the Local Group dwarf galaxy of Phoenix. They have been derived...

The force of gravity acting within the volume occupied by young, compact, and massive super star clusters is here shown to drive in situ all the matter...

We present a detailed study of the hydrodynamics of the matter reinserted by massive stars via stellar winds and supernovae explosions in young assembling...

Here we discuss the properties of star cluster winds in the supercritical, catastrophic cooling regime. We demonstrate that catastrophic cooling inhibits...

In an earlier paper we modelled the far-infrared emission from a star-forming galaxy using the photoionization code CLOUDY and presented metallicity sensitive...

We review the structural properties of giant extragalactic H II regions and H II galaxies based on two-dimensional hydrodynamic calculations and propose an...
