The Transition from "Normal" to "Broad Absorption Line Quasar" of Ton 34
Normal Broad Absorption Line Quasar
2011/1/10
We report the emergence of a high velocity, broad absorption line outflow in the luminous quasar Ton 34, at z=1.928. The outflow is detected through an ultraviolet CIV broad absorption line, in a spec...
Colour gradients in normal and compact early-type galaxies at 1

2010/11/15
We have derived colour gradients for a sample of 20 early-type galaxies (ETGs) at 1 < z
spec < 2 selected from the GOODS-South field. The sample includes both nor-mal ETGs (13) having effective radii...
The Larson-Tinsley Effect in the UV: Interacting vs. `Normal' Spiral Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We compare the UV-optical colors of a well-defined set of optically-selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion fo...
