Evolution of active galactic nuclei broad-line region clouds: low- and high-ionization lines
D. R. Goncalves, A. C. S. Friaca, V. Jatenco-Pereira
The formation of quasar broad-line region (BLR) clouds via thermal instability in the presence of Alfven heating has been discussed by Goncalves et al. (1993a, 1996). In particular…
Coupled spheroid and black-hole formation, and the multifrequency detectability of active galactic nuclei and submillimetre sources
E. N. Archibald, J. S. Dunlop, R. Jimenez +3
We use a simple model of spheroid formation to explore the relationship between the creation of stars and dust in a massive proto galaxy and the growth of its central black hole. T…
The cosmological evolution of colour gradients in spheroids
Amancio Friaca, Roberto Terlevich
The analysis of the four-colour maps of galaxies in the Hubble Deep Field has revealed in the sample of 0.4<z<1 early-type field galaxies the existence of ellipticals with a predom…
