Mass function and assembly of dark halos: an approach to inventory isolated overdense regions in random fields
C. Firmani, V. Avila-Reese
In order to attain a statistical description of the evolution of cosmic density fluctuations in agreement with results from the numerical simulations, we introduce a probability co…
The stellar and dark halo mass assembly of galaxies
V. Avila-Reese, C. Firmani
The emerging empirical picture of galaxy stellar mass (Ms) assembly shows that galaxy population buildup proceeds from top to down in Ms. By connecting galaxies to LCDM halos and t…
On the stellar and baryonic mass fractions of central blue and red galaxies
A. Rodriguez-Puebla, V. Avila-Reese, C. Firmani +1
By means of the abundance matching technique, we infer the local stellar and baryonic mass-halo mass (Ms-Mh and Mb-Mh) relation for central blue and red galaxies separately in the…
Galaxy downsizing evidenced by hybrid evolutionary tracks
C. Firmani, V. Avila-Reese
An unified picture of stellar and halo mass build-up as a function of mass is presented. Inferred stellar-dark halo mass relations of galaxies, Ms-Mh, out to z=4 together with aver…
Can galaxy outflows and re-accretion produce the downsizing in specific star formation rate of late-type galaxies?
C. Firmani, V. Avila-Reese, A. Rodriguez-Puebla
The observations show that less massive the galaxies are, the higher on average is their specific star formation rate (SSFR = SFR/Ms, Ms is the stellar mass). Such a trend, called…
The size evolution of galaxy discs formed within Lambda Cold Dark Matter haloes
C. Firmani, V. Avila-Reese
By means of galaxy evolutionary models, we explore the direct consequences of the LCDM cosmogony on the size evolution of galactic discs, avoiding intentionally the introduction of…
