How cold is Dark Matter? Constraints from Milky Way Satellites (2009)
Maccio', Andrea V., Fontanot, Fabio
We test the luminosity function of Milky Way satellites as a constraint for the nature of Dark Matter particles. We perform dissipationless high-resolution N-body simulations of the evolution of...
Faint Lyman-Break galaxies as a crucial test for galaxy formation models (2009)
Faro, Barbara Lo, Monaco, Pierluigi, Vanzella, Eros, Fontanot, Fabio, Silva, Laura, Cristiani, Stefano
It has recently been shown that galaxy formation models within the LambdaCDM cosmology predict that, compared to the observed population, small galaxies (with stellar masses < 10^{11} M_sun) form too...
On the origin and properties of Ultrafaint Milky Way Satellites in a LCDM Universe (2009)
Maccio', Andrea V., Kang, Xi, Fontanot, Fabio, Somerville, Rachel S., Koposov, Sergey E., Monaco, Pierluigi
We study the origin and properties of satellite galaxies within Milky Way size haloes as predicted in LCDM model, making use of hydrodynamic and N-body simulations as well as of three different...
Fontanot, Fabio, De Lucia, Gabriella, Monaco, Pierluigi, Somerville, Rachel S., Santini, Paola
[abridged] It has been widely claimed that several lines of observational evidence point towards a "downsizing" (DS) of the process of galaxy formation over cosmic time. This behavior is sometimes...
Modeling multi-wavelength properties of high redshift galaxies (2009)
Monaco, Pierluigi, Fontanot, Fabio, Lo Faro, Barbara, De Lucia, Gabriella, Vanzella, Eros, Somerville, Rachel, ...
Fontanot, Fabio, Somerville, Rachel S., Silva, Laura, Monaco, Pierluigi, Skibba, Ramin
The treatment of dust attenuation is crucial in order to compare the predictions of galaxy formation models with multiwavelength observations. Most past studies have either used simple analytic...
The Correlation of Star Formation Quenching with Internal Galaxy Properties and Environment (2008)
Kimm, Taysun, Somerville, Rachel S., Yi, Sukyoung K., Salim, Samir, Fontanot, Fabio, ...
We investigate the correlation of star formation quenching with internal galaxy properties and large scale environment (halo mass) in empirical data and theoretical models. We make use of the...
Expected z>5 QSO number counts in large area deep near-infrared surveys (2007)
Fontanot, Fabio, Somerville, Rachel S., Jester, Sebastian
The QSO luminosity function at z>5 provides strong constraints on models of joint evolution of QSO and their hosts. However, these observations are challenging because the low space densities of...
Reproducing the assembly of massive galaxies within the hierarchical cosmogony (2007)
Fontanot, Fabio, Monaco, Pierluigi, Silva, Laura, Grazian, Andrea
In order to gain insight into the physical mechanisms leading to the formation of stars and their assembly in galaxies, we compare the predictions of the MOdel for the Rise of GAlaxies aNd Active...
Fontanot, Fabio, Cristiani, Stefano, Monaco, Pierluigi, Nonino, Mario, Vanzella, Eros, Brandt, W. Niel, ...
Aims: In this work the luminosity function of QSOs is measured in the redshift range 3.5
The MORGANA model for the rise of galaxies and active nuclei (2007)
Monaco, Pierluigi, Fontanot, Fabio, Taffoni, Giuliano
We present the Model for the Rise of Galaxies and Active Nuclei (MORGANA), a new code for the formation and evolution of galaxies and active galactic nuclei (AGNs). Starting from the merger trees of...

The luminosity function of high-redshift QSOs (2006)
Fontanot, Fabio, Cristiani, Stefano, Monaco, Pierluigi, Vanzella, Eros, Nonino, Mario, Brandt, W. Niel, ...
We measure the luminosity function of QSOs in the redshift range 3.5 < z < 5.2 for the absolute magnitude interval -21 < M_{145} < -28. Suitable criteria are defined to select faint QSOs in the GOODS...
The MORGANA model for the rise of galaxies and active nuclei (2006)
Monaco, Pierluigi, Fontanot, Fabio, Taffoni, Giuliano
We present the MOdel for the Rise of GAlaxies aNd Active nuclei (MORGANA). Starting from the merger trees of dark matter halos and a model for the evolution of substructure within the halos, the...
Monaco, Pierluigi, Murante, Giuseppe, Borgani, Stefano, Fontanot, Fabio
The high end of the stellar mass function of galaxies is observed to have little evolution since z~1. This represents a stringent constraint for merger--based models, aimed at explaining the...
The effect of stellar feedback and quasar winds on the AGN population (2006)
Fontanot, Fabio, Monaco, Pierluigi, Cristiani, Stefano, Tozzi, Paolo
In order to constrain the physical processes that regulate and downsize the AGN population, the predictions of the MOdel for the Rise of GAlaxies aNd Active nuclei (MORGANA) are compared to...

Recovering the Initial Condition of our Local Universe from NOG and PSCz Catalogues (2003)
Fontanot, Fabio, Monaco, Pierluigi, Borgani, Stefano
We apply the ZTRACE algorithm to the optical NOG and infra-red PSCz galaxy catalogues to reconstruct the pattern of primordial fluctuations that have generated our local Universe. We check that the...
