We report the discovery of a very cool d/sdL7+T7.5p common proper motion binary system, SDSS J1416+13AB, found by cross-matching the United Kingdom Infrared...
We report the discovery of a T8.5 dwarf, which is a companion to the M4 dwarf Wolf 940. At a distance of 12.50+0.75-0.67 pc, the angular separation of 32 arcsec...
The Discovery of Binary White Dwarfs that will Merge Within 500 Myr
We present radial velocity observations of four extremely low-mass (0.2 M sun) white dwarfs (WDs). All four stars show peak-to-peak radial velocity variations...
The Discovery of More than 2000 White Dwarfs in the Globular Cluster ω Centauri
We present deep multiband (F435W, F625W, and F658N) photometric data of the globular cluster ω Cen collected with the Advanced Camera for Surveys on board the...
The discovery of the most UV-Ly α luminous star-forming galaxy: a young, dust- and metal-poor starburst with QSO-like luminosities
We report the discovery of BOSS-EUVLG1 at z = 2.469, by far the most luminous, almost un-obscured star-forming galaxy known at any redshift. First classified as...
We have carried out a search for late-type T dwarfs in the UKIRT Infrared Deep Sky Survey Galactic Plane Survey 6th Data Release. The search yielded two...
The discovery of WASP-151b, WASP-153b, WASP-156b: Insights on giant planet migration and the upper boundary of the Neptunian desert
To investigate the origin of the features discovered in the exoplanet population, the knowledge of exoplanets' mass and radius with a good precision (≲10%) is...
The discovery space of ELT-ANDES. Stars and stellar populations
The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is the optical and near-infrared high-resolution echelle spectrograph envisioned for the Extremely...
The discrepancy between dynamical and stellar masses in massive compact galaxies traces non-homology
For many massive compact galaxies, their dynamical masses (Mdyn ∝ σ2re) are lower than their stellar masses (M⋆). We analyse the unphysical mass discrepancy M⋆...
