We use Atacama Large Millimetre Array and Jansky Very Large Array observations of the galaxy cluster Cl J1449+0856 at z = 1.99, in order to study how dust-obscured star formation, interstellar medium content, and active galactic nuclei activity are linked to environment and galaxy interactions during the crucial phase of high-z cluster assembly. We

A measurement is presented of the Z/γ ^{*} → τ τ cross section in {pp} collisions at √{s} = 13 TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3 fb^{-1}. The product of the inclusive cross section and branching fraction is measured to be σ ( {pp} → Z/γ ^{*} {+X}) B(Z/γ ^{*} → τ τ ) = 1848 ±

Many galaxies host pronounced (circum)nuclear starbursts, fuelled by infalling gas. Such activity drives the secular evolution of the nucleus and may also generate super winds which enrich the interstellar and intergalactic medium. Given the intense radiation fields and extreme gas densities present within these nuclear regions, star formation may

The Time Inference with MUSE in Extragalactic Rings (TIMER) project is a survey using the integral-field spectrograph Multi Unit Spectroscopic Explorer (MUSE) on the VLT to study 24 nearby barred galaxies with prominent central structures, such as nuclear rings or inner discs. One of our main goals is to estimate the cosmic epoch when galaxy discs

Context. Most of our knowledge of the stellar component of galaxies is based on the analysis of distant systems and comes from integrated light data. It is important to test whether the results of the star formation histories (SFH) obtained with standard full-spectrum fitting methods are in agreement with those obtained through colour-magnitude

We present a catalog of relative proper motions for 368,787 stars in the 30 Doradus region of the Large Magellanic Cloud (LMC), based on a dedicated two-epoch survey with the Hubble Space Telescope and supplemented with proper motions from our pilot archival study. We demonstrate that a relatively short epoch difference of three years is sufficient
