We report the discovery of a cold planet with a very low planet/host mass ratio of q = (4.09 ± 0.27) × 10 -5, which is similar to the ratio of Uranus/Sun (q = 4.37 × 10 -5) in the solar system. The Bayesian estimates for the host mass, planet mass, system distance, and planet-host projected separation are M host = 0.76 ± 0.40M ☉, M planet = 10.3 ±

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

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

We present the high-resolution spectroscopic analysis of two new extremely metal-poor star (EMPS) candidates in the dwarf spheroidal galaxy Sextans. These targets were preselected from medium-resolution spectra centered around the Ca II triplet in the near-infrared and were followed-up at higher resolution with VLT/UVES. We confirm their low

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

HARMONI, an adaptive optics (AO) assisted integral field spectrograph (IFS), will be the core spectroscopic capability for the European Southern Observatory's (ESO's) Extremely Large Telescope (ELT). It will support several AO modes and achieve diffraction-limited (≈10 mas) to seeing-limited spatial resolution, at low to high spectral resolving
