A cooperative approach among methods for photometric redshifts estimation: an application to KiDS data
Stefano Cavuoti, Crescenzo Tortora, Massimo Brescia +8
Photometric redshifts (photo-z's) are fundamental in galaxy surveys to address different topics, from gravitational lensing and dark matter distribution to galaxy evolution. The Ki…
The Herschel-ATLAS: a sample of 500μm-selected lensed galaxies over 600 square degrees
M. Negrello, S. Amber, A. Amvrosiadis +43
We present a sample of 80 candidate strongly lensed galaxies with flux density above 100mJy at 500μm extracted from the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS)…
Supernova rates from the SUDARE VST-Omegacam search II. Rates in a galaxy sample
M. T. Botticella, E. Cappellaro, L. Greggio +24
This is the second paper of a series in which we present measurements of the Supernova (SN) rates from the SUDARE survey. In this paper, we study the trend of the SN rates with the…
Halo ellipticity of GAMA galaxy groups from KiDS weak lensing
Edo van Uitert, Henk Hoekstra, Benjamin Joachimi +14
We constrain the average halo ellipticity of ~2 600 galaxy groups from the Galaxy And Mass Assembly (GAMA) survey, using the weak gravitational lensing signal measured from the ove…
A discrete chemo-dynamical model of the giant elliptical galaxy NGC 5846: dark matter fraction, internal rotation and velocity anisotropy out to six effective radii
Ling Zhu, Aaron J. Romanowsky, Glenn van de Ven +7
We construct a suite of discrete chemo-dynamical models of the giant elliptical galaxy NGC 5846. These models are a powerful tool to constrain both the mass distribution and intern…
Abundance ratios and IMF slope in the dwarf elliptical galaxy NGC~1396 with MUSE
J. J. Mentz, F La Barbera, R. F. Peletier +16
Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (M, Mass M), located in the Fornax cluster, have been performed with the VLT/…
KiDS-450: Cosmological parameter constraints from tomographic weak gravitational lensing
H. Hildebrandt, M. Viola, C. Heymans +33
We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg of imaging data from the Kilo Degree Survey (KiDS). For a flat $…
Dependence of GAMA galaxy halo masses on the cosmic web environment from 100 square degrees of KiDS weak lensing data
Margot M. Brouwer, Marcello Cacciato, Andrej Dvornik +31
Galaxies and their dark matter haloes are part of a complex network of mass structures, collectively called the cosmic web. Using the tidal tensor prescription these structures can…
The Extended Spatial Distribution of Globular Clusters in the Core of the Fornax Cluster
R. D'Abrusco, M. Cantiello, M. Paolillo +16
We report the discovery of a complex extended density enhancement in the Globular Clusters (GCs) in the central ( Mpc) of the Fornax cluster,…
The Fornax Deep Survey with VST. I. The extended and diffuse stellar halo of NGC~1399 out to 192 kpc
E. Iodice, M. Capaccioli, A. Grado +13
[Abrigded] We have started a new deep, multi-imaging survey of the Fornax cluster, dubbed Fornax Deep Survey (FDS), at the VLT Survey Telescope. In this paper we present the deep p…
