Quiet Sun magnetism plays an important role in the global energy balance of the solar atmosphere. The study of the magnetism of the quiet Sun has been a major effort in the last decades, and, as a result, very important advances in our knowledge have been achieved. The recent commissioning of the Daniel K. Inouye Solar Telescope, the largest ground

In this paper, we present a device, designed to be used in a space payload, capable of correcting any arbitrary polarization state. The device consists of a set of three liquid-crystal variable-retarder (LCVR) cells, in which by selecting the appropriate values of the voltage to be applied in each of them, it can correct the undesirable effects. In

For the 696 trans-Neptunian objects (TNOs) with absolute magnitudes 5.5 < H r < 8.2 detected in the Dark Energy Survey, we characterize the relationships between their dynamical state and physical properties—namely H r, indicating size; colors, indicating surface composition; and flux variation semiamplitude A, indicating asphericity and surface

Context. The coldest metal-poor population made up of T and Y dwarfs can serve as an archaeological tracer of our Galaxy because these very old objects have retained their pristine material. The optical properties of these objects are important for characterising their atmospheric properties. Aims. We aim to further characterise the optical

The interaction between plasma flow and magnetic field transports magnetic energy and helicity through the photosphere. It plays an important role in driving the dynamics in the solar atmosphere. In my talk, I will first show the application of a newly developed flow tracking method, DAVE4VMwDV, in studying the field-aligned flow near the polarity

The Large Scale Polarization Explorer (LSPE) project, funded by the Italian Space Agency (ASI), includes the development of LSPE-Strip, a ground-based radio telescope for observing Cosmic Microwave Background (CMB) anisotropies. LSPE-Strip, nearing its construction phase, will operate from the Teide Observatory in Tenerife, employing 49 coherent
