The Large Binocular Telescope (LBT) Observatory pioneered Adaptive Optics (AO) technologies such as Adaptive Secondary Mirror (ASM), Pyramid wavefront sensor, and Ground-layer AO using Rayleigh lasers at 8 to 10m class telescopes. We have initiated an effort to turn LBT AO into a facility-class capability. The effort involves (1) building an AO team with AO development capability, (2) improving the robustness of the AO, (3) developing in-house AO expertise to maintain and troubleshoot the AO systems, (4) automating processes for efficient on-sky operation, (5) tracking performance metrics and cultivating accountability for on-sky AO performance, and (6) minimizing the operational risks for the ASMs. We present the status of these developments. LBTO continues its efforts to develop innovative technology. We explore the next phase of AO developments, including Agile Extreme Adaptive Optics (AgXAO) on the DX side of the LINC-NIRVANA optical bench to overcome the limitation imposed by varying and large atmospheric seeing at Mount Graham. AgXAO implementation includes the development of (1) a high-order, high-sensitivity wavefront sensor, (2) a high-density deformable mirror with 3000 actuators and next-generation ASM with about 950 actuators, (3) active optics integration, (4) vibration and wavefront piston control, (5) atmospheric turbulence measurements and weather forecast integration, and (6) a visible camera and an AO-corrected narrow-field fiber-coupled IFU spectrograph using one of the existing workhorse visible spectrographs. Developing AgXAO on the SX side, too, would enable Fizeau imaging in the visible wavelengths. AgXAO will also serve as a general-purpose high-contrast (and subsequently a Fizeau imaging) Testbed on LBT to test advanced wavefront control algorithms, including astrophotonics experiments, and machine learning algorithms with minimal impact on routine science operations. We propose developing AgXAO through student projects to train the next-generation scientists and engineers for the extremely large telescope (ELT) era. The ultimate goal is to push large aperture ground-based telescopes to their performance limits and make them competitive with space telescopes in terms of PSF stability and performance to enable breakthrough science.

SHARK-NIR is an instrument providing high-contrast coronagraphic imaging, dual band imaging and low resolution spectroscopy in Y, J and H bands, taking advantage of the high performance of the Large Binocular Telescope (LBT) AO systems. Its main scientific drivers is the detection and characterization of exoplanets, circumstellar disks, Solar System small bodies and acrive galactic nuclei. Binocular observations are provided by exploiting the synergy with SHARK-VIS (operating in V band) and LMIRCam of LBTI (operating from K to M band). SHARK-NIR was shipped to LBT in June 2022, and up to November 2022 was the subject of the three pre-commissioning runs: the first to install and test the instrument in the high-bay LBT clean tent, the second to install and align the instrument to the telescope and the third to perform daytime testing. This pre-commissioning phase resulted in the successful alignment of the instrument with a very good internal optical quality and the performance of additional tests using simulated turbulence injected through LBT Adaptive Secondary Mirror. In January 2023 we had the first commissioning run and the instrument first light, in which we successfully tested the imaging capabilities with and without the Gaussian Lyot coronagraph. In March 2023 we had the second commissioning run, in which despite the bad weather we successfully performed a variety of technical activities, as well as preliminary testing of the Shaped Pupil coronagraph. After two additional commissioning runs in May and October, our first early scientific run in October 2023 focused on the Taurus star formation region, a region populated by targets of considerable scientific interest. In this paper we will give an overview of commissioning and the early science phases running from October 2023 to May 2024, focusing on the technical challenges we overcame and future work needed to push the instrument to its very limit, as well as presenting the first preliminary scientific results.
