We present ALMA Atacama Compact Array (ACA) 870 μm continuum maps of 28 infrared-bright SDSS quasars with Herschel/SPIRE detections at redshifts 2-4, the largest such sample ever observed with ALMA. The ACA detections are centred on the SDSS coordinates to within 1 ″ for about 80 per cent of the sample. Larger offsets indicate that the far-infrared

Context. The BL Lac object S5 0716+714, a highly variable blazar, underwent an impressive outburst in January 2015 (Phase A), followed by minor activity in February (Phase B). The MAGIC observations were triggered by the optical flux observed in Phase A, corresponding to the brightest ever reported state of the source in the R-band. Aims.The

The determination of fundamental parameters in low-mass X-ray binaries (LMXBs) typically relies on measuring the radial velocity curve of the companion star through optical or near-infrared spectroscopy. It was recently suggested that high resolution X-ray spectroscopy might enable a measurement of the radial velocity curve of the compact object by

Measurements of Higgs boson properties in the H → γγ decay channel are reported. The analysis is based on data collected by the CMS experiment in proton-proton collisions at √{s}=13 TeV during the 2016 LHC running period, corresponding to an integrated luminosity of 35.9 fb-1. Allowing the Higgs mass to float, the measurement yields a signal

The mass of the top quark is measured using a sample of {{ {t}}\overline{{ {t}}}} events collected by the CMS detector using proton-proton collisions at √{s}=13 {TeV} at the CERN LHC. Events are selected with one isolated muon or electron and at least four jets from data corresponding to an integrated luminosity of 35.9 {fb}^{-1}. For each event

The production of a { {Z}} boson, decaying to two charged leptons, in association with jets in proton-proton collisions at a centre-of-mass energy of 13 {TeV} is measured. Data recorded with the CMS detector at the LHC are used that correspond to an integrated luminosity of 2.19 {fb}^ {-1}. The cross section is measured as a function of the jet
