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

We present a comprehensive analysis of the planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Both surveys collected enough data over the planetary anomaly to enable an unambiguous planet detection. Such survey detections of planetary anomalies are needed to build a robust

OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source, which includes very high energy (VHE, $E\gt $ 100 GeV) $\gamma$-ray data taken by the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov telescopes) and H.E.S.S. (High Energy Stereoscopic System) imaging
