| Abstract: |
SHARP is a conceptual study for a near-IR (0.9-2.4 μm) spectrograph conceived to exploit the capabilities of future ground-based Adaptive Optics (AO)-assisted Extremely Large Telescope (ELTs). Its capabilities would perfectly fit the space-based Habitable World Observatory (HWO). The instrument concept is driven by the goal of creating a spectrograph capable of tackling the most important questions in astrophysics and cosmology, from exploring primordial galaxies to studying the properties of candidate Habitable Worlds, bridging the gap between the local and the distant Universe. This requires versatility to accommodate diverse observational needs. SHARP consists of two main units: NEXUS, a slit Multi-Object Spectrograph (MOS) optimized for detecting the faintest sources, and VESPER, a multi-object Integral Field Unit (multi-IFU) designed for brighter ones. The high angular resolution, multi-object capabilities, and near-IR coverage enable studies of stellar and planetary formation, exoplanet atmospheres, high-redshift galaxy properties, as well as the search for primordial Population III stars. SHARP would exploit the HWO aperture and complement the other UV/Vis spectrographs by providing spectroscopic follow-up to the High-Resolution Imager's near-IR observations that would otherwise remain uncovered. |
