The growth of galactic bulges through mergers in LCDM haloes revisited. I. Present-day properties

Jesus Zavala, Vladimir Avila-Reese, Claudio Firmani +1

We use the Millennium I and II cosmological simulations to revisit the impact of mergers in the growth of bulges in central galaxies in the LCDM scenario. We seed galaxies within t…

The specific star formation rate and stellar mass fraction of low-mass central galaxies in cosmological simulations

V. Avila-Reese, P. Colín, A. González-Samaniego +4

(Abridged) By means of high-resolution cosmological simulations in the context of the LCDM scenario, the specific star formation rate (SSFR=SFR/Ms, Ms is the stellar mass)--Ms and…

Short versus Long Gamma-Ray Bursts: spectra, energetics, and luminosities

G. Ghirlanda, L. Nava, G. Ghisellini +2

We compare the spectral properties of 79 short and 79 long Gamma-Ray Bursts (GRBs) detected by BATSE and selected with the same limiting peak flux. Short GRBs have a low-energy spe…

Time-resolved spectral correlations of long-duration Gamma-Ray Bursts

C. Firmani, J. I. Cabrera, V. Avila-Reese +4

For a sample of long GRBs with known redshift, we study the distribution of the evolutionary tracks on the rest-frame luminosity-peak energy Liso-Ep' diagram. We are interested in…

On the baryonic, stellar, and luminous scaling relations of disk galaxies

V. Avila-Reese, J. Zavala, C. Firmani +1

We explore how the slopes and scatters of the scaling relations of disk galaxies (Vm-L[-M], R-L[-M], and Vm-R) do change when moving from B to K bands and to stellar and baryonic q…

Gamma-Ray Bursts, new cosmological beacons

V. Avila-Reese, C. Firmani, G. Ghisellini +1

Long Gamma-Ray Bursts (GRBs) are the brightest electromagnetic explosions in the Universe, associated to the death of massive stars. As such, GRBs are potential tracers of the evol…
