The 31 brightest galaxies (mB ≤ 15 mag) inside the virial radius of the Fornax cluster were observed from the centres to the outskirts with the Multi Unit Spectroscopic Explorer on the Very Large Telescope. These observations provide detailed high-resolution maps of the line-of-sight kinematics, line strengths of the stars, ionised gas reaching 2-3

Within the actions carried out by the Directorate General of Cultural Heritage of the Government of Aragon in relation to the judicial procedure on the pillage of the Celtiberian city of Aratis (Aranda de Moncayo, Zaragoza), a large area was located with several concentrations of tumular structures in the area of Penas Pasera, previously

A second galaxy “missing dark matter” (NGC 1052-DF4) has been reported recently. Here we show, using the location of the tip of the red giant branch (TRGB), that the distance to this galaxy is 14.2 ± 0.7 Mpc. This locates the galaxy 6 Mpc closer than previously determined. We also analyze the distances to the brightest galaxies in the field of view

In October 2018, Swift announced the discovery of a new Galactic X-ray transient, Swift J1858. Just before Sun-angle constraints rendered the system unobservable, follow-up observations revealed extreme flaring activity, of a kind that has so far only been seen in the famous black hole X-ray binary (BHXRB) V404 Cyg during its 2015 eruption and in

Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to an understanding of its formation and evolution. However, stellar ages are difficult to obtain since they cannot be measured from observations, but require comparison with stellar models 1. Alternatively, age distributions can be derived by applying the robust

Aims: Our scientific goal is to provide revised membership lists of the α Per, Pleiades, and Praesepe clusters exploiting the second data release of Gaia and produce five-dimensional maps (α, δ, π, μα cos δ, μδ) of these clusters. Methods: We implemented the kinematic method combined with the statistical treatment of parallaxes and proper motions
