TL;DR: In this paper, the authors analyzed archival Hubble Space Telescope F606W images of a sample of 18 dE galaxy candidates in the Coma Cluster and confirmed that the light profiles of the underlying host galaxies display systematic departures from an exponential model that are correlated with the model independent host galaxy luminosity and are not due to biasing from the nuclear component.

TL;DR: In this article, the authors obtained spectra with the 10 m Keck telescope of a sample of 24 galaxies having colors consistent with star-forming galaxies at redshifts 2 z 4.5 in the Hubble deep field (HDF).

TL;DR: In this paper, the authors analyzed archival HST F606W images of 18 dwarf elliptical (dE) galaxy candidates in the Coma Cluster and modeled the full radial extent of their light profiles by simultaneously fitting a PSF-convolved Sersic R^(1/n) model and, when necessary, either a central point-source or a central PSF convolutional Gaussian.

TL;DR: In this paper, a spectroscopic study of 51 compact field galaxies with redshifts z 0.4 < z < 1.7 has been conducted, showing that these galaxies are on average 10 times more massive than the general field population.

TL;DR: In this paper, the authors present a spectroscopic study of 51 compact field galaxies with redshifts z 0.7 and show that these galaxies have similar SFRs per unit mass to those at z < 0.5.
