The mass-dependent star formation histories of disk galaxies: infall model versus observations
R. X. Chang, J. L. Hou, S. Y. Shen +1
We introduce a simple model to explore the star formation histories of disk galaxies. We assume that the disk origins and grows by continuous gas infall. The gas infall rate is par…
Milky Way vs Andromeda: a tale of two disks
J. Yin, J. L. Hou, N. Prantzos +4
We study the chemical evolution of the disks of the Milky Way (MW) and of Andromeda (M31), in order to reveal common points and differences between the two major galaxies of the Lo…
Quasar spectral energy distribution in EUV restored from associated absorbers: indications to the HeII opacity of the quasar accretion disk wind
S. A. Levshakov, I. I. Agafonova, D. Reimers +2
(abridged) Aims. To reconstruct the spectral shape of the quasar ionizing radiation in the extreme-UV range (1Ryd <= E < 10Ryd) from the analysis of narrow absorption lines (NAL) o…
Physical properties of DLA metallicity and neutral hydrogen column density
J. L. Hou, C. G. Shu, W. P. Chen +2
We investigate some basic properties of Damped Lyman alpha systems based on the Semi-Analytical model of disk galaxy formation theory. We derive the DLA metallicity, column density…
Chemical evolution and depletion pattern in Damped Lyman-alpha (DLA) systems
J. L. Hou, S. Boissier, N. Prantzos
In this paper we point out a previously unnoticed anticorrelation between the observed abundance ratio [X/Zn] (where Zn is assumed to be undepleted and X stands for the refractorie…
