Rotating magnetic structures are common in astrophysics, from vortex tubes and tornadoes in the Sun all the way to jets in different astrophysical systems. The physics of these objects often combine inertial, magnetic, gas pressure, and gravitational terms. Also, they often show approximate symmetries that help simplify the otherwise rather

A search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb-1 at √{s}=13 TeV recorded by the CMS detector at the LHC. No evidence for such a signal is observed

Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy of √{ s } = 13TeV. The search uses a signature of a single lepton, large jet and bottom quark jet multiplicities, and high sum of large-radius jet masses, without any requirement on the missing transverse momentum in an

Searches for resonances decaying into pairs of jets are performed using proton-proton collision data collected at √{s}=13 TeV corresponding to an integrated luminosity of up to 36 fb-1. A low-mass search, for resonances with masses between 0.6 and 1.6 TeV, is performed based on events with dijets reconstructed at the trigger level from calorimeter

Context. The first Gaia Data Release (DR1) significantly improved the previously available proper motions for the majority of the Tycho-2 stars. Aims: We wish to detect runaway stars using Gaia DR1 proper motions and compare our results with previous searches. Methods: Runaway O stars and BA supergiants were detected using a 2D proper motion method

We present spectra obtained with the 10.4 m Gran Telescopio Canarias telescope of 13 Galactic H II regions, most of them of very low ionization degree. The objects are located along the Galactic disc, with RG from 5.7 to 16.1 kpc. We determine Te([N II]) for all of them. We obtain - for the first time - a radial abundance gradient of N that is
