MAXI J1348-630 is a low mass X-ray binary discovered in 2019 during a bright outburst. During this event, the system experienced both hard and soft states following the standard evolution. We present multi-epoch optical and near-infrared spectroscopy obtained with X-shooter at the Very Large Telescope. Our dataset includes spectra taken during the

Aimed at the detection of cosmological gas being accreted onto galaxies in the local universe, we examined the Hα emission in the halo of 164 galaxies in the field of view of the Multi-Unit Spectroscopic Explorer Wide survey (MUSE-Wide) with observable Hα (redshift <0.42). An exhaustive screening of the corresponding Hα images led us to select 118

Integral Field Spectropolarimetry (IFS) makes feasible the simultaneous measurement of a 2D field with the use of an Integral Field Unit (IFU). Slicer-based IFUs rearrange an input 2D Field of View (FoV) to an output long-slit that is used to feed a standard spectrograph. The spatial resolution reachable with this technique is determined by the

Context. Gliese-832 (GJ 832) is an M2V star hosting a massive planet on a decade-long orbit, GJ 832b, discovered by radial velocity (RV). Later, a super Earth or mini-Neptune orbiting within the stellar habitable zone was reported (GJ 832c). The recently determined stellar rotation period (45.7 ± 9.3 days) is close to the orbital period of putative

One of the main goals of the European Solar Telescope (EST), a 4.2-m telescope, is to clarify the roots of the magnetic processes taking place in the solar atmosphere. This goal has a top-level requirement: perform simultaneous spectropolarimetric measurements in multiple spectral lines. For this purpose, EST will be equipped with a set of

The European Solar Telescope is a 4-m class solar telescope planned to include a multi-conjugate adaptive optics system (MCAO) for high spatial resolution over a circular field of view with 60" diameter. MCAO systems constitute a very complex and still not mature technology in both optical and control terms. To deal with this issue, a downscaled
