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…
Dark Matter Equilibria in Galaxies and Galaxy Systems
A. Lapi, A. Cavaliere
[abridged] In the dark matter (DM) halos embedding galaxies and galaxy systems the `entropy' K = σ^2 / ρ^{2/3} (a quantity that combines the radial velocity dispersion σwith the de…
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 Baryonic and Dark Matter Properties of High Redshift Gravitationally Lensed Disk Galaxies
P. Salucci, A. M. Swinbank, A. Lapi +4
We present a detailed study of the structural properties of four gravitationally lensed disk galaxies at z=1. Modelling the rotation curves on sub-kpc scales we derive the values f…
