Prospects of Deep Field Surveys with Global-MCAO on an ELT
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +12
Several astronomical surveys aimed at the investigation of the extragalactic components were carried out in order to map systematically the universe and its constituents. An excell…
Data processing on simulated data for SHARK-NIR
E. Carolo, D. Vassallo, J. Farinato +22
A robust post processing technique is mandatory to analyse the coronagraphic high contrast imaging data. Angular Differential Imaging (ADI) and Principal Component Analysis (PCA) a…
A Holographic Diffuser Generalised Optical Differentiation Wavefront Sensor
Luca Marafatto, Roberto Ragazzoni, Daniele Vassallo +12
The wavefront sensors used today at the biggest World's telescopes have either a high dynamic range or a high sensitivity, and they are subject to a linear trade off between these…
Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies
G. De Rosa, M. M. Fausnaugh, C. J. Grier +99
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…
A testing facility for AO on-sky demonstrations at the Copernico's Telescope within the ADONI framework
S. Chinellato, R. Ragazzoni, J. Farinato +21
In the context of ADONI - the ADaptive Optics National laboratory of INAF - we are arranging for a facility, accessible to the AO community, in which visiting multi-purpose instrum…
Ingot Laser Guide Stars Wavefront Sensing
Roberto Ragazzoni, Elisa Portaluri, Valentina Viotto +11
We revisit one class of z-invariant WaveFront sensor where the LGS is fired aside of the telescope aperture. In this way there is a spatial dependence on the focal plane with respe…
