Ground-based imagers assisted by Multi Conjugate Adaptive Optics (MCAO) systems are the technological frontier to obtain high-quality stellar photometry and astrometry in crowded fields at the highest possible spatial resolution. I will review the main scientific results obtained in the last years in the field of stellar populations by using AO data and key advancements in their exploitation....
In this talk I will discuss state-of-the art scientific use and
future perspectives of integral field spectroscopy assisted by
adaptive optics as an optimal multi-object capability in dense
stellar fields.
We discuss some science cases that will exploit the Extremely Large Telescope (ELT) diffraction limit power. We focus on a novel and detailed analysis of a young star cluster in the Large Magellanic cloud, R136–like. The main aim of this study is to quantify precision and accuracy of stellar proper motions measurements in crowded field when using an ELT working at its diffraction limit. This...
We plan to discuss a few medium resolution near infrared spectral features that can be used to contrain metallicity distribution of old (RR Lyrae, Type II Cepheids) and young (Classical Cepheids) stellar tracers in crowded and highly reddened regions of the Galactic inter bulge and of the Galactic thin disk. In particular, we will focus our attention on the key opportunity to couple NIR/MIR...
MCAO are a cornerstone technology for current and future telescopes (g.e. ELT). The synergy between high-resolution near-infrared imagers and MCAO systems is already leading the way for the characterisation of the stellar content and the structural properties of all of those systems in the Galaxy for which optical observations are almost totally useless. I will give an overview of the results...
The formation and evolution of galaxies, and in particular of the Milky Way, is one of the major puzzles of astrophysics: a detailed physical scenario is still missing, and its understanding requires the joint effort of observations and theories. The evolution with time of the chemical content of a galaxy is one of the topic constraints to understand the most relevant mechanisms driving...
We present optical and NIR photometry for the Galactic globular M30. We focussed our attention on this globular because it is a post core collapsed, this means that the innermost regions display a cusp in density distribution. Moreover, M30 was observed with gound- and space-based (HST) telescopes. In particular, NIR images were collected with both seeing limited NIR array (SOFI@NTT),...
