Galaxy populations in the Hydra I cluster from the VEGAS survey II. The ultra-diffuse galaxy population
Antonio La Marca, Enrichetta Iodice, Michele Cantiello +18
In this work, we extend the catalog of low-surface brightness (LSB) galaxies, including Ultra-Diffuse Galaxy (UDG) candidates, within of the Hydra I cluster of…
The Fornax3D project: The assembly history of massive early-type galaxies in the Fornax cluster from deep imaging and integral field spectroscopy
M. Spavone, E. Iodice, G. D'Ago +16
This work is based on high quality integral-field spectroscopic data obtained with the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT). The 21 brightest…
Galaxy populations in the Hydra I cluster from the VEGAS survey I. Optical properties of a large sample of dwarf galaxies
Antonio La Marca, Reynier Peletier, Enrichetta Iodice +17
At ~50 Mpc, the Hydra I cluster of galaxies is among the closest cluster in the z=0 Universe, and an ideal environment to study dwarf galaxy properties in a cluster environment. We…
Formation of an ultra-diffuse galaxy in the stellar filaments of NGC3314A: caught in act?
Enrichetta Iodice, Antonio La Marca, Michael Hilker +13
The VEGAS imaging survey of the Hydra I cluster reveals an extended network of stellar filaments to the south-west of the spiral galaxy NGC3314A. Within these filaments, at a proje…
The VST Early-type GAlaxy Survey: Exploring the Outskirts and Intra-cluster Regions of Galaxies in the Low-surface-brightness Regime
Enrichetta Iodice, Marilena Spavone, Massimo Capaccioli +15
The VST Early-type GAlaxy Survey (VEGAS) is a deep, multi-band (u, g, r, i) imaging survey, carried out with the 2.6-metre VLT Survey Telescope (VST) at ESO's Paranal Observatory i…
Telltale signs of metal recycling in the circumgalactic medium of a galaxy
N. Tejos, S. López, C. Ledoux +15
We present gravitational-arc tomography of the cool-warm enriched circumgalactic medium (CGM) of an isolated galaxy (``G1'') at . Combining VLT/MUSE adaptive-optics…
The Complex Gaseous and Stellar environments of the nearby dual AGN Mrk 739
Dusán Tubín, Ezequiel Treister, Giuseppe D'ago +7
We present Integral Field Spectroscopic (IFS) observations of the nearby () dual Active Galactic Nuclei (AGN) Mrk 739, whose projected nuclear separation is 3.4~kp…
INSPIRE: INvestigating Stellar Population In RElics -- I. Survey presentation and pilot program
C. Spiniello, C. Tortora, G. D'Ago +12
Massive ETGs are thought to form through a two-phase process. At early times, an intense and fast starburst forms blue and disk-dominated galaxies. After quenching, the remaining s…
Discovery of two Einstein crosses from massive post--blue nugget galaxies at z>1 in KiDS
N. R. Napolitano, R. Li, C. Spiniello +18
We report the discovery of two Einstein Crosses (ECs) in the footprint of the Kilo-Degree Survey (KiDS): KIDS J232940-340922 and KIDS J122456+005048. Using integral field spectrosc…
Central velocity dispersion catalog of LAMOST-DR7 galaxies
Nicola R. Napolitano, Giuseppe D'Ago, Crescenzo Tortora +6
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a major facility to carry out spectroscopic surveys for cosmology and galaxy evolution studies. The sevent…
The Next Generation Fornax Survey (NGFS): VII. A MUSE view of the nuclear star clusters in Fornax dwarf galaxies
Evelyn J. Johnston, Thomas H. Puzia, Giuseppe D'Ago +16
Clues to the formation and evolution of Nuclear Star Clusters (NSCs) lie in their stellar populations. However, these structures are often very faint compared to their host galaxy,…
Building the largest spectroscopic sample of ultra-compact massive galaxies with the Kilo Degree Survey
Diana Scognamiglio, Crescenzo Tortora, Marilena Spavone +14
Ultra-compact massive galaxies UCMGs, i.e. galaxies with stellar masses and effective radii kpc, are very rare systems, in partic…
VEGAS: VST Early-type GAlaxy Survey. V. IC 1459 group: Mass assembly history in low density environments
E. Iodice, M. Spavone, A. Cattapan +9
This paper is based on the multi-band VST Early-type GAlaxy Survey (VEGAS) with the VLT Survey Telescope (VST). We present new deep photometry of the IC1459 group in g and r band.…
Intrinsic Morphology of Ultra-diffuse Galaxies
Yu Rong, Xiao-Yu Dong, Thomas H. Puzia +10
With the published data of apparent axis ratios for 1109 ultra-diffuse galaxies (UDGs) located in 17 low-redshift (z~ 0.020 - 0.063) galaxy clusters and 84 UDGs in 2 intermediate-r…
The first sample of spectroscopically confirmed ultra-compact massive galaxies in the Kilo Degree Survey
C. Tortora, N. R. Napolitano, M. Spavone +25
We present results from an ongoing investigation using the Kilo Degree Survey (KiDS) on the VLT Survey Telescope (VST) to provide a census of ultra-compact massive galaxies (UCMGs)…
