The dramatic size evolution of elliptical galaxies and the quasar feedback
L. Fan, A. Lapi, G. De Zotti +1
Observations have evidenced that passively evolving massive galaxies at high redshift are much more compact than local galaxies with the same stellar mass. We argue that the observ…
Long Gamma-Ray Bursts and Their Host Galaxies at High Redshift
A. Lapi, N. Kawakatu, Z. Bosnjak +4
Motivated by the recent observational and theoretical evidence that long Gamma-Ray Bursts (GRBs) are likely associated with low metallicity, rapidly rotating massive stars, we exam…
Missing Baryons, from Clusters to Groups of Galaxies
A. Cavaliere, A. Lapi
From clusters to groups of galaxies, the powerful bremsstrahlung radiation L_X emitted in X rays by the intracluster plasma is observed to decline sharply with lowering virial temp…
Observability of the virialization phase of spheroidal galaxies with radio arrays
M. Massardi, A. Lapi, G. De Zotti +2
In the standard galaxy formation scenario plasma clouds with a high thermal energy content must exist at high redshifts since the proto-galactic gas is shock heated to the virial t…
The Universal Rotation Curve of Spiral Galaxies. II The Dark Matter Distribution out to the Virial Radius
P. Salucci, A. Lapi, C. Tonini +3
In the current LambdaCDM cosmological scenario, N-body simulations provide us with a Universal mass profile, and consequently a Universal equilibrium circular velocity of the viria…
A highly obscured and strongly clustered galaxy population discovered with the Spitzer Space Telescope
M. Magliocchetti, L. Silva, A. Lapi +4
The ~800 optically unseen (R>25.5) 24mum-selected sources in the complete Spitzer First Look Survey sample (Fadda et al. 2006) with F[24mum]>0.35 mJy are found to be very strongly…
