The effect of environment on the structure of disc galaxies
We study the influence of environment on the structure of disc galaxies, using imfit to measure the g- and r-band structural parameters of the surface...
The effects of seeing on the parameters of the Sèrsic profile are studied in an analytical form using a Gaussian point spread function. The surface brightness...
The effects of seeing on Sérsic profiles - II. The Moffat PSF
The effects of seeing on Sérsic r1/n profile parameters are extensively studied using a Moffat function. This analytical approximation to the point spread...
The Einstein Cross: Constraint on Dark Matter from Stellar Dynamics and Gravitational Lensing
We present two-dimensional line-of-sight stellar kinematics of the lens galaxy in the Einstein Cross, obtained with the GEMINI 8 m telescope, using the GMOS...
The Faber-Jackson relation for early-type galaxies: dependence on the magnitude range
Aims: Previous studies have found that the coefficients and intrinsic dispersions of both the Kormendy relation and the Fundamental Plane depend on the...
The first Frontier Fields cluster: 4.5 μm excess in a z ~ 8 galaxy candidate in Abell 2744
Aims: We present in this letter the first analysis of a z ~ 8 galaxy candidate found in the Hubble and Spitzer imaging data of Abell 2744 as part of the Hubble...
The Fornax Deep Survey (FDS) with VST. VI. Optical properties of the dwarf galaxies in the Fornax cluster
Context. Dwarf galaxies are the most common type of galaxies in galaxy clusters. Due to their low mass, they are more vulnerable to environmental effects than...
The Fornax Deep Survey with the VST. IV. A size and magnitude limited catalog of dwarf galaxies in the area of the Fornax cluster
Context. The Fornax Deep Survey (FDS), an imaging survey in the u', g', r', and i'-bands, has a supreme resolution and image depth compared to the previous...
