We present the study of the dynamical status of the galaxy cluster CL1821+643, a rare and intriguing cool-core cluster hosting a giant radio halo. We base our analysis on new spectroscopic data for 129 galaxies acquired at the Italian Telescopio Nazionale Galileo. We also use spectroscopic data available from the literature and photometric data

A measurement is presented of the associated production of a single top quark and a W boson in proton-proton collisions at √{s}=13 TeV by the CMS Collaboration at the CERN LHC. The data collected corresponds to an integrated luminosity of 35.9 fb-1. The measurement is performed using events with one electron and one muon in the final state along

An unsettled question concerning the formation and distribution of massive stars is whether they must be born in massive clusters and, if found in less dense environments, whether they must have migrated there. With the advent of wide-area digital photometric surveys, it is now possible to identify massive stars away from prominent Galactic

Context. Multiplanet systems are excellent laboratories to test planet formation models as all planets are formed under the same initial conditions. In this context, systems transiting bright stars can play a key role, since planetary masses, radii, and bulk densities can be measured. Aims: GJ 9827 (K2-135) has recently been found to host a tightly

Context. The Kepler Object of Interest Network (KOINet) is a multi-site network of telescopes around the globe organised to follow up transiting planet-candidate Kepler objects of interest (KOIs) with large transit timing variations (TTVs). Its main goal is to complete their TTV curves, as the Kepler telescope no longer observes the original Kepler

The PRIMitive Asteroid Spectroscopic Survey (PRIMASS) is a visible and near-infrared study of primitive asteroids throughout the asteroid belt. Nesvorny et al. 2015 defined 6 primitive families in the inner asteroid belt: Polana-Eulalia, Erigone, Sulamitis, Clarissa, Chaldaea, and Klio. PRIMASS has already characterized Polana in visible and NIR
