Several authors have reported that the dynamical masses of massive compact galaxies (M_⋆ ≳ 10^11 M_⊙, r_e ∼ 1 kpc), computed as M_dyn=5.0 σ_e^2r_e/GMdyn=5.0 σe2re/G, are lower than their stellar masses M_⋆. In a previous study from our group, the discrepancy is interpreted as a breakdown of the assumption of homology that underlie the M_dyn determinations. Here, we present new spectroscopy of six redshift z ≈ 1.0 massive compact ellipticals from the Extended Groth Strip, obtained with the 10.4… Expand

Dark matter inside early-type galaxies as function of mass and redshift
We study the behaviour of the dynamical and stellar mass inside the effective radius (re) of early-type galaxies (ETGs). We use several samples of ETGs -ranging from 19 000 to 98 000 objects- fromExpand
Dynamical masses and non-homology of massive elliptical galaxies grown by dry mergers
We study whether dry merger-driven size growth of massive elliptical galaxies depends on their initial structural concentration, and analyse the validity of the homology hypothesis for virial massExpand
Massive relic galaxies prefer dense environments
We study the preferred environments of $z \sim 0$ massive relic galaxies ($M_\star \gtrsim 10^{10}~\mathrm{M_\odot}$ galaxies with little or no growth from star formation or mergers since $z \simExpand
Stellar populations of galaxies in the ALHAMBRA survey up to $z \sim 1$. IV. Properties of quiescent galaxies on the stellar mass$-$size plane
We perform a comprehensive study of the stellar population properties of quiescent galaxies as a function of size and stellar mass to constrain the physical mechanism governing the stellar massExpand
Observations contradict galaxy size and surface brightness predictions that are based on the expanding universe hypothesis
In a non-expanding universe surface brightness is independent of distance or redshift, while in an expanding universe it decreases rapidly with both. Similarly, for objects of the same luminosity,Expand

A high stellar velocity dispersion for a compact massive galaxy at redshift z = 2.186
TLDR
The velocity dispersion is very high at  km s-1, consistent with the mass and compactness of the galaxy inferred from photometric data, which would indicate significant recent structural and dynamical evolution of massive galaxies over the past 10 Gyr. Expand
