Dark Matter and IMF normalization in Virgo dwarf early-type galaxies
C. Tortora, F. La Barbera, N. R. Napolitano
In this work we analyze the dark matter (DM) fraction, , and mass-to-light ratio mismatch parameter, (computed with respect to a Milky-Way-like IMF), for a sample…
Supernova rates from the SUDARE VST-Omegacam search. I
E. Cappellaro, M. T. Botticella, G. Pignata +23
We describe the observing strategy, data reduction tools and early results of a supernova (SN) search project, named SUDARE, conducted with the ESO VST telescope aimed at measuring…
Shapley Supercluster Survey: Construction of the Photometric Catalogues and i-band Data Release
A. Mercurio, P. Merluzzi, G. Busarello +10
The Shapley Supercluster Survey is a multi-wavelength survey covering an area of ~23 deg^2 (~260 Mpc^2 at z=0.048) around the supercluster core, including nine Abell and two poor c…
The first and second data releases of the Kilo-Degree Survey
Jelte T. A. de Jong, Gijs A. Verdoes Kleijn, Danny R. Boxhoorn +46
The Kilo-Degree Survey (KiDS) is an optical wide-field imaging survey carried out with the VLT Survey Telescope and the OmegaCAM camera. KiDS will image 1500 square degrees in four…
Machine Learning based photometric redshifts for the KiDS ESO DR2 galaxies
Stefano Cavuoti, Massimo Brescia, Crescenzo Tortora +9
We estimated photometric redshifts (zphot) for more than 1.1 million galaxies of the ESO Public Kilo-Degree Survey (KiDS) Data Release 2. KiDS is an optical wide-field imaging surv…
A new search for variability-selected active galaxies within the VST SUDARE-VOICE survey: the Chandra Deep Field South and the SERVS-SWIRE area
S. Falocco, D. De Cicco, M. Paolillo +19
This work makes use of the VST observations to select variable sources. We use also the IR photometry, SED fitting and X-ray information where available to confirm the nature of th…
VEGAS: A VST Early-type GAlaxy Survey. I. Presentation, wide-field surface photometry, and substructures in NGC 4472
Massimo Capaccioli, Marilena Spavone, Aniello Grado +10
We present the VST Early-type GAlaxy Survey (VEGAS), which is designed to obtain deep multiband photometry in g, r, i, of about one hundred nearby galaxies down to 27.3, 26.8, and…
Early type galaxies and structural parameters from ESO public survey KiDS
N. Roy, N. R. Napolitano, F. La Barbera +5
The Kilo Degree survey (KiDS) is a large-scale optical imaging survey carried out with the VLT Survey Telescope (VST), which is the ideal tool for galaxy evolution studies. We expe…
Systematic variation of central mass density slope in early-type galaxies
C. Tortora, F. La Barbera, N. R. Napolitano +3
We study the total density distribution in the central regions ( effective radius, ) of early-type galaxies (ETGs), using data from the SPIDER survey. We model ea…
Galaxy evolution within the Kilo-Degree Survey
C. Tortora, N. R. Napolitano, F. La Barbera +8
The ESO Public Kilo-Degree Survey (KiDS) is an optical wide-field imaging survey carried out with the VLT Survey Telescope and the OmegaCAM camera. KiDS will scan 1500 square degre…
Strong lens search in the ESO public Survey KiDS
N. R. Napolitano, G. Covone, N. Roy +10
We have started a systematic search of strong lens candidates in the ESO public survey KiDS based on the visual inspection of massive galaxies in the redshift range . As…
Gravitational Lensing Analysis of the Kilo Degree Survey
Konrad Kuijken, Catherine Heymans, Hendrik Hildebrandt +32
The Kilo-Degree Survey (KiDS) is a multi-band imaging survey designed for cosmological studies from weak lensing and photometric redshifts. It uses the ESO VLT Survey Telescope wit…
The masses of satellites in GAMA galaxy groups from 100 square degrees of KiDS weak lensing data
Cristóbal Sifón, Marcello Cacciato, Henk Hoekstra +23
We use the first 100 sq. deg. of overlap between the Kilo-Degree Survey (KiDS) and the Galaxy And Mass Assembly (GAMA) survey to determine the galaxy halo mass of ~10,000 spectrosc…
Towards a census of super-compact massive galaxies in the Kilo Degree Survey
C. Tortora, F. La Barbera, N. R. Napolitano +12
The abundance of compact, massive, early-type galaxies (ETGs) provides important constraints to galaxy formation scenarios. Thanks to the area covered, depth, excellent spatial res…
