The MICADO instrument for the ESO ELT will provide Adaptive Optics (AO) diffraction-limited NIR imaging and spectroscopy. A critical component of MICADO is the Point Spread Functio…
The MICADO first light imager for the ELT: Simulated Observations of Star Forming Clumps at Cosmic Noon
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +18
Galaxies at redshift z2-6 exhibit prominent star-forming regions (clumps). Characterisation of these galactic structures requires both high sensitivity and spatial resolution…
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…
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…
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…
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…
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…
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…
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…
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…
Hubble Space Telescope survey of Magellanic Cloud star clusters. Photometry and astrometry of 113 clusters and early results
A. P. Milone, G. Cordoni, A. F. Marino +29
In the past years, we have undertaken an extensive investigation of LMC and SMC star clusters based on HST data. We present photometry and astrometry of stars in 101 fields observe…
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…
