Premature dismissal of high-redshift elliptical galaxies
Raul Jimenez, Amancio Friaca, James Dunlop +3
It has recently been argued that single-collapse high-redshift models for elliptical galaxy formation can be rejected because they predict large numbers of very red galaxies at int…
On the origin of Damped Lyman-alpha systems: a case for LSB galaxies?
Raul Jimenez, David V. Bowen, Francesca Matteucci
We use a model of galaxy disk formation to explore the metallicities, dust content, and neutral-gas mass density of damped Lyman- (D\lya) absorbers. We find that the [Zn/H] abun…
Towards an accurate determination of the age of the Universe
R. Jimenez
In the past 40 years a considerable effort has been focused in determining the age of the Universe at zero redshift using several stellar clocks. In this review I will describe the…
Galaxy Formation and Evolution: Low Surface Brightness Galaxies
Raul Jimenez, Paolo Padoan, Francesca Matteucci +1
We investigate in detail the hypothesis that low surface brightness galaxies (LSB) differ from ordinary galaxies simply because they form in halos with large spin parameters. We co…
Galaxy Evolution, Deep Galaxy Counts and the Near-IR Cosmic Infrared Background
R. Jimenez, A. Kashlinsky
Accurate synthetic models of stellar populations are constructed and used in evolutionary models of stellar populations in forming galaxies. Following their formation, the late typ…
Old high-redshift galaxies and primordial density fluctuation spectra
J. A. Peacock, R. Jimenez, J. S. Dunlop +5
We have discovered a population of extremely red galaxies at which have apparent stellar ages of $\gs 3$ Gyr, based on detailed spectroscopy in the rest-frame ultravi…
