The Fornax cluster provides a uniquely compact laboratory in which to study the detailed history of early-type galaxies and the role played by the environment in driving their evolution and their transformation from late-type galaxies. Using the superb capabilities of the Multi Unit Spectroscopic Explorer on the Very Large Telescope, high-quality

Far-infrared spectroscopy is a powerful tool complementing the potential of mid-infrared spectroscopy for the search and identification of organic molecules in space. The far-infrared spectra of a total of 29 amino acids are reported in this study. In addition to the spectra of 20 common proteinogenic amino acids, spectra of a selection of nine non

Results of a search for the standard model Higgs boson produced in association with a top quark pair ( t\overline{t}H ) in final states with electrons, muons, and hadronically decaying τ leptons are presented. The analyzed data set corresponds to an integrated luminosity of 35.9 fb-1 recorded in proton-proton collisions at √{s}=13 TeV by the CMS

The Pristine survey uses narrow-band photometry on the region of the Ca II H & K absorption lines to find extremely metal-poor stars. With a spectroscopic follow-up sample of 205 stars in the magnitude range 14 V 18, we compute the success rates for finding extremely metal-poor stars and modify the selection criteria used to select stars for

Directly imaged substellar companions around stars are key objects for better understanding the formation and evolution of brown dwarfs and massive planets, as we can infer physical properties like the age, distance or metallicity from their host stars. Moreover, we can characterize them spectroscopically, seeking for features that may provide

We have serendipitously discovered that Leoncino Dwarf, an ultrafaint, low-metallicity record-holder dwarf galaxy, may have hosted a transient source, and possibly exhibited a change in morphology, a shift in the centre of brightness, and peak variability of the main (host) source in images taken approximately 40 yr apart; it is highly likely that
