Probing General Relativity in galactic scales at z
Carlos R. Melo-Carneiro, Cristina Furlanetto, Ana L. Chies-Santos
General Relativity (GR) has been successfully tested mainly at Solar system scales; however, galaxy-scale tests have become popular in the last few decades. In this work, we invest…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
J-PLUS: On the identification of new cluster members in the double galaxy cluster A2589 & A2593 using PDFs
A. Molino, M. V. Costa-Duarte, C. Mendes de Oliveira +28
We aim to use multi-band imaging from the Phase-3 Verification Data of the J-PLUS survey to derive accurate photometric redshifts (photo-z) and look for potential new members in th…
The Nature of Faint Fuzzies from the Kinematics of NGC1023
A. L. Chies-Santos, A. Cortesi, D. S. M. Fantin +3
Faint fuzzies are metal-rich apparently-old star clusters with unusually large radii (7-15 pc), found mostly in S0 galaxies, whose source remain obscure. To identify their origins,…
Planetary Nebula Spectrograph survey of S0 galaxy kinematics. II. Clues to the origins of S0 galaxies
A. Cortesi, M. R. Merrifield, L. Coccato +11
The stellar kinematics of the spheroids and discs of S0 galaxies contain clues to their formation histories. Unfortunately, it is difficult to disentangle the two components and to…
The Planetary Nebula Spectrograph survey of S0 galaxy kinematics. Data and Overview
A. Cortesi, M. Arnaboldi, L. Coccato +11
The origins of S0 galaxies remain obscure, with various mechanisms proposed for their formation, likely depending on environment. These mechanisms would imprint different signature…
The old globular cluster system of NGC 4365: new VLT/FORS2 spectra
A. L. Chies-Santos, S. S. Larsen, M. Kissler-Patig
We present new spectroscopic observations of a sample of globular clusters (GCs) in the Virgo Cluster elliptical NGC4365. The great majority of the objects analysed here, overlap o…
An optical/NIR survey of globular clusters in early-type galaxies III. On the colour bimodality of GC systems
A. L. Chies-Santos, S. S. Larsen, M. Cantiello +4
The interpretation that bimodal colour distributions of globular clusters (GCs) reflect bimodal metallicity distributions has been challenged. Non-linearities in the colour to meta…
An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
A. L. Chies-Santos, S. S. Larsen, H. Kuntschner +5
Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fract…
An optical/NIR survey of globular clusters in early-type galaxies. I. Introduction and data reduction procedures
A. L. Chies-Santos, S. S. Larsen, E. M. Wehner +3
Context: The combination of optical and near-infrared (NIR) colours has the potential to break the age/metallicity degeneracy and offers a better metallicity sensitivity than optic…
