Status of the PSF Reconstruction Work Package for MICADO ELT
Andrea Grazian, Matteo Simioni, Carmelo Arcidiacono +20
MICADO is a workhorse instrument for the ESO ELT, allowing first light capability for diffraction limited imaging and long-slit spectroscopy at near-infrared wavelengths. The PSF R…
BRUTE, PSF Reconstruction for the SOUL pyramid-based Single Conjugate Adaptive Optics facility of the LBT
Carmelo Arcidiacono, Andrea Grazian, Anita Zanella +11
The astronomical applications greatly benefit from the knowledge of the instrument PSF. We describe the PSF Reconstruction algorithm developed for the LBT LUCI instrument assisted…
FLYEYE family tree, from smart fast cameras to MezzoCielo
Roberto Ragazzoni, Silvio Di Rosa, Carmelo Arcidiacono +8
We developed game-changing concepts for meter(s) class very-wide-field telescopes, spanning three orders of magnitude of the covered field of view. Multiple cameras and monocentric…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
LBT SOUL data as a science test bench for MICADO PSF-R tool
Matteo Simioni, Carmelo Arcidiacono, Roland Wagner +14
Current state-of-the-art adaptive optics (AO) provides ground-based, diffraction-limited observations with high Strehl ratios (SR). However, a detailed knowledge of the point sprea…
MICADO PSF-Reconstruction work package description
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +25
The point spread function reconstruction (PSF-R) capability is a deliverable of the MICADO@ESO-ELT project. The PSF-R team works on the implementation of the instrument software de…
FlyEye Ground-Based Telescope: Unveiling New Frontiers in Astronomical Science
Carmelo Arcidiacono, Matteo Simioni, Roberto Ragazzoni +15
The FlyEye design makes its debut in the ESA's NEOSTEL developed by OHB-Italia. This pioneering FlyEye telescope integrates a monolithic 1-meter class primary mirror feeding 16 CCD…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. X. The radial distribution of stellar populations in NGC 2808
Matteo Simioni, Antonino P. Milone, Luigi R. Bedin +4
Due to their extreme helium abundance, the multiple stellar populations of the globular cluster NGC 2808 have been widely investigated from a photometric, spectroscopic, and kinema…
LRPayne: Stellar parameters and abundances from low-resolution spectra
Nagaraj Vernekar, Lorenzo Spina, Sara Lucatello +4
Aims. This paper introduces LRPayne, a novel algorithm designed for the efficient determination of stellar parameters and chemical abundances from low-resolution optical spectra, w…
The MICADO first light imager for the ELT: the PSF Reconstruction Software
Andrea Grazian, Elisa Portaluri, Matteo Simioni +10
MICADO is the first-light camera of the ESO ELT, allowing NIR imaging and long-slit spectroscopy assisted by adaptive optics. MICADO is now entering its construction phase, and the…
A numerical simulation study of an astrometry case for MORFEO at the ELT
Carmelo Arcidiacono, Elisa Portaluri, Marco Gullieuszik +7
We report results from numerical simulations assessing astrometry measurements with the Multiconjugate Adaptive Optics Relay for ELT Observations (MORFEO) instrument on the Extreme…
Towards the MICADO@ELT PSF-R with simulated and real data
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +5
Observations close to the diffraction limit, with high Strehl ratios from Adaptive Optics (AO)-assisted instruments mounted on ground-based telescopes are a reality and will become…
The Canarias Einstein Ring: a Newly Discovered Optical Einstein Ring
Margherita Bettinelli, Matteo Simioni, Antonio Aparicio +5
We report the discovery of an optical Einstein Ring in the Sculptor constellation, IAC J010127-334319, in the vicinity of the Sculptor Dwarf Spheroidal Galaxy. It is an almost comp…
Point spread function reconstruction for SOUL+LUCI LBT data
Matteo Simioni, Carmelo Arcidiacono, Roland Wagner +14
This paper presents the status of an ongoing project aimed at developing a PSF reconstruction software for adaptive optics (AO) observations. In particular, we test for the first t…
Statistical analysis of Galactic globular cluster type properties
Matteo Simioni, Antonio Aparicio, Giampaolo Piotto
The analysis of pseudo-colour diagrams, the so-called chromosome maps, of Galactic globular clusters (GCs) permits to classify them into type I and type II clusters. Type II GCs ar…
What are the Pillars of Reionization? Revising the AGN Luminosity Function at z~5
Andrea Grazian, Emanuele Giallongo, Konstantina Boutsia +22
In the past, high-z AGNs were given a minor role as possible drivers of reionization, despite initial evidences in favor of their large space densities at low luminosities by Chand…
