SUMMARY:High ionisation absorption in low mass X-ray binaries
DESCRIPTION:The advent of the new generation of X-ray telescopes yielded a significant step forward in our understanding of ionised absorption generated in the accretion discs of X-ray binaries. It appears now clear that these relatively weak and narrow absorption features\, sporadically present in the X-ray spectra of some systems\, are actually the signature of equatorial outflows\, which might carry away more matter than that being accreted. Therefore\, they play a major role in the accretion phenomenon. These outflows (or ionised atmospheres) are ubiquitous during the softer states but absent during the power-law dominated\, hard states\, suggesting a strong link with the state of the inner accretion disc\, presence of the radio-jet and the properties of the central source. I will review the current understanding of this field.

SUMMARY:Cool\, luminous stars to probe chemistry & kinematics in dusty-extincted stellar systems
DESCRIPTION:Evolved\, cool giants and supergiants are among the brightest stars in any stellar system and are\neasily observable out to large distances.\nWhen observed at infrared wavelengths\, these cool stars can be also used to probe the stellar content\nin environments severely obscured by dust\, such as the central regions of galaxies.\nProgress in our astrophysical comprehension of the stellar content in such extreme environments\ngoes together with the technological advance of IR instrumentation.\nIn this talk I will first present briefly the IR instrument context over the last two decades\,\nand then I will review some of the most recent results in probing stellar chemistry\nand kinematics in the center of the Milky Way and in nearby galaxies.

SUMMARY:Extreme adaptive optics at the Large Binocular Telescope
DESCRIPTION:After a brief introduction about adaptive optics and the Large Binoculare Telescope\, I will present the LBT’s extreme adaptive optic system. I will show its current capabilities\, main scientific results and the performance improvement offered by the upcoming upgrade. Finally\, I will show how the LBT AO technology impacted the design of the 8m-class and the next generation of ground based telescopes.

SUMMARY:Linking massive black hole spin evolution to galactic dynamics
DESCRIPTION:The evolution of the spin of massive black holes (MBHs) is driven by accretion of gas and/or by black hole binary coalescences. I will discuss the physical processes involved in the MBH spin evolution\, and present the results of a semi-analytical model that manages to reproduce the distribution of spins obtained from X-ray spectroscopy.

SUMMARY:Metals outside galaxies: what do we learn from observations?
DESCRIPTION:The observed properties and evolution of galaxies in the Universe require the existence of feedback mechanisms regulating the star formation and finally quenching it. The presence of winds\, possibly transporting the gas outside the viral radius\, has been confirmed observationally in local and high redshift objects. In this talk\, I will briefly review how scientist have confirmed the presence of heavy elements outside galaxies using the observation of QSO absorption lines and I will present and discuss new results based on the highest signal-to-noise ratio\, high resolution QSO spectrum ever obtained.

SUMMARY:The early growth of (super)massive black holes
DESCRIPTION:With detections of quasars powered by increasingly massive black holes\n(BH) at increasingly early times in cosmic history over the past decade\,\nthere has been correspondingly rapid progress made on the theory of early\nBH formation and growth. I review the emerging picture of how the first\nmassive BHs formed from the primordial gas and then grew to supermassive\nscales\, and discuss the initial conditions for the formation of the\nprogenitors of these seed BHs\, the factors dictating the initial masses\nwith which they form\, and their initialstages of growth via accretion\,\nwhich may occur at super-Eddington rates.

SUMMARY:Exploring the realm of an AGN
DESCRIPTION:The environment of Active Galactic Nuclei (AGN) is the result of accretion and injection of matter in and around a supermassive black hole. Through high resolution X-ray spectroscopy of both present and future instruments\, the most extreme gas environments of the AGN can be studied. In this talk I will present our recent results on outflows and obscuration in AGN. I will also illustrate the tremendous improvement that future instruments will offer in this field.
