HARMONI is the adaptive optics assisted, near-infrared and visible light integral field spectrograph for the Extremely Large Telescope (ELT). A first light instrument, it provides the work-horse spectroscopic capability for the ELT. As the project approaches its Final Design Review milestone, the design of the instrument is being finalized, and the

We present an update on the overall integration progress of the WEAVE next-generation spectroscopy facility for the William Herschel Telescope (WHT), now scheduled for first light in early-2021, with almost all components now arrived at the observatory. We also present a summary of the current planning behind the 5-year initial phase of survey

MAGIC is a system of two 17m diameter Imaging Atmospheric Cherenkov Telescopes (IACTs) situated on the observatory of the Roque de los Muchachos on the island of La Palma, 2200m asl. MAGIC is currently in operation for the observation of VHE gamma-ray sources. Here we report the installation of a system to perform intensity interferometry

LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and fundamental physics. JAXA selected LiteBIRD in May 2019 as a strategic large-class (L-class) mission, with its expected launch in the late 2020s using JAXA's H3 rocket

Mid-infrared observations are a vital tool for the study of a wide range of astrophysical phenomena. However, ground-based mid-infrared detectors must overcome the challenge of the overwhelming thermal background from sky and telescope emissions making them prohibitively costly for smaller (< 3 m) facilities. We describe the design and testing of a

We report the development of MuSCAT3, a four channel simultaneous imager installed on the 2m Faulkes Telescope North at Haleakala Observatory on Maui, Hawai'i. MuSCAT3 has a capability of 4-color simultaneous imaging in g (400-550 nm), r (550-700 nm), i (700-820 nm), and z s (820-920 nm) bands with four independent 2048×2048 pixel CCDs, each having
