High resolution morphology and surface photometry of KIG 685 and KIG 895 with ARGOS+LUCI
R. Rampazzo, M. Uslenghi, I. Y. Giorgiev +14
We aim to refine the sample of isolated early-type galaxies in the AMIGA catalogue via high resolution imaging. Here we report the result from a pilot study investigating two candi…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XIX. A Chemical Tagging of the Multiple Stellar Populations Over the Chromosome Maps
A. F. Marino, A. P. Milone, A. Renzini +8
The HST UV Survey of Globular Clusters (GCs) has investigated GCs and their stellar populations. In previous papers of this series we have introduced a pseudo two-color diagram, "c…
Metallicity variations in the Type II globular cluster NGC6934
A. F. Marino, D. Yong, A. P. Milone +7
The Hubble Space Telescope photometric survey of Galactic globular clusters (GCs) has revealed a peculiar "chromosome map" for NGC6934. Besides a typical sequence, similar to that…
Photometry and spectroscopy of multiple populations along the AGB of NGC2808 and NGC6121 (M4)
A. F. Marino, A. P. Milone, D. Yong +8
We present a photometric and spectroscopic study of multiple populations along the asymptotic-giant branch (AGB) of the intermediate-metallicity globular clusters (GCs) NGC2808 and…
Investigating early-type galaxy evolution with a multiwavelength approach. II. The UV structure of 11 galaxies with Swift-UVOT
R. Rampazzo, P. Mazzei, A. Marino +6
GALEX detected a significant fraction of early-type galaxies showing Far-UV bright structures. These features suggest the occurrence of recent star formation episodes. We aim at un…
A Spitzer-IRS view of early-type galaxies with cuspy/core nuclei and with fast/slow rotation
R. Rampazzo, O. Vega, A. Bressan +3
The recent literature suggests that an evolutionary dichotomy exists for early-type galaxies (Es and S0s, ETGs) whereby their central photometric structure (cuspy versus core centr…
Multi-wavelength Hubble Space Telescope photometry of stellar populations in NGC288
G. Piotto, A. P. Milone, A. F. Marino +5
We present new UV observations for NGC288, taken with the WFC3 detector on board the Hubble Space Telescope, and combine them with existing optical data from the archive to explore…
The double sub-giant branch of NGC 6656 (M22): a chemical characterization
A. F. Marino, A. P. Milone, C. Sneden +14
We present an abundance analysis of 101 subgiant branch (SGB) stars in the globular cluster M22. Using low resolution FLAMES/GIRAFFE spectra we have determined abundances of the ne…
The two metallicity groups of the globular cluster M22: a chemical perspective
A. F. Marino, C. Sneden, R. P. Kraft +11
We present a detailed chemical composition analysis of 35 red giant stars in the globular cluster M22. High resolution spectra for this study were obtained at five observatories, a…
Nucleosynthesis in the Stellar Systems omega Cen and M22
G. S. Da Costa, A. F. Marino
The stellar system omega Centauri is well known for the large range in abundance among its member stars. Recent work has indicated that the globular cluster M22 (NGC 6656) also pos…
New HST WFC3/UVIS observations augment the stellar-population complexity of omega Centauri
Bellini A., Bedin L. R., Piotto G. +3
We used archival multi-band Hubble Space Telescope observations obtained with the Wide-Field Camera 3 in the UV-optical channel to present new important observational findings on t…
Chemical composition of stellar populations in Omega Centauri
A. F. Marino, G. Piotto, R. Gratton +5
We derive abundances of Fe, Na, O, and s-elements from GIRAFFE@VLT spectra for more than 200 red giant stars in the Milky Way satellite Omega Centauri. Our preliminary results are…
A double stellar generation in the Globular Cluster NGC6656 (M 22). Two stellar groups with different iron and s-process element abundance
A. F. Marino, A. P. Milone, G. Piotto +4
AIMS. In this paper we present the chemical abundance analysis from high resolution UVES spectra of seventeen bright giant stars of the Globular Cluster M~22. RESULTS. We obtained…
