The evolution of disk galaxies
V. Avila-Reese, C. Firmani
We study the evolution of disk galaxies using galaxy evolutionary models with initial and boundary conditions linked to the hierarchical formation scenario. Disks galaxies are mode…
On the origin of the color Tully-Fisher and color-magnitude relations of disk galaxies
V. Avila-Reese, C. Firmani
We propose and show that the dependence of the internal face-on dust absorption upon B-band luminosity reported by Wang & Heckman (1996) for a sample of late-type galaxies may expl…
Properties of disk galaxies in a hierarchical formation scenario
V. Avila-Reese, C. Firmani
We used galaxy evolutionary models in a hierarchical inside-out formation scenario to study the origin of the main properties and correlations of disk galaxies. We found that most…
BeppoSax Spectral Survey of soft X-ray selected BL Lacs
A. Wolter, A. Comastri, G. Ghisellini +10
We present X-ray spectra obtained with BeppoSAX (Satellite per Astronomia X) of 10 BL Lac objects, selected from the Einstein Medium Sensitivity and Slew Surveys. We find that in a…
