NGC 288 is a diffuse Galactic globular cluster; it is remarkable in that its low density results in internal accelerations being below the critical MOND a0 acceleration throughout. This makes it an ideal testing ground for MONDian gravity, as the details of the largely unknown transition function between the Newtonian and modified regimes become

Aims: We present V and R photometry of the gravitationally lensed quasars WFI 2033-4723 and HE 0047-1756. The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope at the ESO La Silla observatory from 2008 to 2012. Methods: Differential photometry has been carried out using the image subtraction method as implemented in the

A measurement of the top quark pair production (toverline{t} ) cross section in proton-proton collisions at the centre-of-mass energy of 8 {TeV} is presented using data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.6 {fb}^{- {1}}. This analysis is performed in the toverline{t} decay channels with one

The MAGIC telescopes, located at the Roque de los Muchachos Observatory (2200 a.s.l.) in the Canary Island of La Palma, can perform observations pointing directly the sea. This permits to search for signatures of air showers induced by tau neutrinos in the PeV-EeV energy range arising from the ocean. We have studied the MAGIC response to such

The extremely metal-poor (XMP) galaxies analyzed in a previous paper have large star-forming regions with a metallicity lower than the rest of the galaxy. Such a chemical inhomogeneity reveals the external origin of the metal-poor gas fueling star formation, possibly indicating accretion from the cosmic web. This paper studies the kinematic

We report the discovery from K2 of a transiting planet in an 18.25-d, eccentric (0.19 ± 0.04) orbit around K2-99, an 11th magnitude subgiant in Virgo. We confirm the planetary nature of the companion with radial velocities, and determine that the star is a metal-rich ([Fe/H] = 0.20 ± 0.05) subgiant, with mass 1.60^{+0.14}_{-0.10} M⊙ and radius 3.1
