IAU-H1 Seminar 2025 October 15th. Title: SHARP - A new-generation spectrograph for the ELT

Title: SHARP - A new-generation multi-mode Near-IR spectrograph for the Extremely Large Telescope to unlock the Universe at unprecedented scales Speaker: Paolo Saracco is First Researcher at the INAF-Osservatorio Astronomico di Brera in Milan (Italy). His research interests focus on galaxy evolution, which he addresses using various methodologies. His primary goal is to reconstruct the mechanisms of galaxy mass assembly by studying their dynamical and stellar population properties at intermediate and high redshifts. Since 2021, he has been Principal Investigator (PI) of the SHARP project, which he conceived, a near-infrared spectrograph designed for the ELT to over-come the limitations of future instruments currently under design. He is currently leading the conceptual and feasibility development of this next-generation instrument. Abstract: The European Southern Observatory’s Extremely Large Telescope (ESO-ELT) is poised to deliver sharper and deeper observational data than the James Webb Space Telescope (JWST), thanks to the synergy between the world’s largest aperture and the cutting-edge Multi-Conjugate Adaptive Optics (MCAO) systems. SHARP (http://sharp.brera.inaf.it) is a conceptual study for a multimode spectrograph in the near-infrared (0.95-2.45 μm), designed to fully exploit these capabilities. SHARP comprises two primary units: NEXUS, a slit-based Multi-Object Spectrograph (MOS), and VESPER, a multi-Integral Field Unit (m-IFU), both optimized to probe angular resolution of around 30 mas. These characteristics will allow SHARP to probe the Universe at physical scales of 100-150 pc over the whole cosmic time, and investigate sub-parsec (less than 0.1 pc) regions within galaxies of the Local Group. This talk outlines the scientific motivation for SHARP and presents the expected instrument’s properties and performance.
