Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
SHINS, the SHARK-NIR Instrument Control Software
Davide Ricci, Fulvio Laudisio, Alessandro Lorenzetto +20
SHARK-NIR is a new compact instrument for coronagraphic imaging, direct imaging, and coronagraphic spectroscopy in the near-infrared wavelengths mounted at LBT. Taking advantage of…
Deep imaging of three accelerating stars using SHARK-NIR and LMIRCam at LBT
D. Mesa, R. Gratton, V. D'Orazi +29
The combination of detection techniques enhances our ability to identify companions orbiting nearby stars. We employed high-contrast imaging to constrain mass and separation of pos…
An Ingot-like class of WaveFront Sensors for Laser Guide Stars
Roberto Ragazzoni, Elisa Portaluri, Davide Greggio +15
Full sky coverage Adaptive Optics on Extremely Large Telescopes requires the adoption of several Laser Guide Stars as references.With such large apertures, the apparent elongation…
TIPTOP: cone effect for single laser adaptive optics systems
Guido Agapito, Cédric Plantet, Fabio Rossi +6
TIPTOP is a python library that is able to quickly compute Point Spread Functions (PSF) of any kind of Adaptive Optics systems. This library has multiple objectives: support the ex…
MAVIS: performance estimation of the adaptive optics module
Guido Agapito, Daniele Vassallo, Cédric Plantet +5
The MCAO Assisted Visible Imager and Spectrograph (MAVIS) is a new visible instrument for ESO Very Large Telescope (VLT). Its Adaptive Optics Module (AOM) must provide extreme adap…
Optical design trade-off study for the AO module of MAVIS
Davide Greggio, Simone Di Filippo, Demetrio Magrin +18
MAVIS (MCAO-Assisted Visible Imager and Spectrograph) is an instrument proposed for the VLT Adaptive Optics Facility (AOF), which is currently in the phase-A conceptual design stud…
MAVIS: system modelling and performance prediction
Guido Agapito, Daniele Vassallo, Cedric Plantet +5
The MCAO Assisted Visible Imager and Spectrograph (MAVIS) Adaptive Optics Module has very demanding goals to support science in the optical: providing 15% SR in V band on a large F…
XAO-assisted coronagraphy with SHARK NIR: from simulations to laboratory tests
Gabriele Umbriaco, Elena Carolo, Daniele Vassallo +22
Several Extreme Adaptive Optics (XAO) systems dedicated to the detection and characterisation of the exoplanets are currently in operation for 8-10 meter class telescopes. Coronagr…
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…
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…
A virtual coronagraphic test bench for SHARK-NIR, the second-generation high contrast imager for the Large Binocular Telescope
D. Vassallo, E. Carolo, J. Farinato +21
In this article, we present a simulator conceived for the conceptual study of an AO-fed high-contrast coronagraphic imager. The simulator implements physical optics: a complex dist…
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…
