The Tarantula FLAMES Survey is an ESO Large Program aimed at disentangling the role of binarity in the evolution of massive stars. We have multiepoch, high resolution and SNR observations of about 1000 massive OB stars in 30 Dor secured with the FLAMES spectrograph at VLT. In this poster we present a general view of the project and the main

The use of integral field spectroscopy is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies, both locally and at high redshift. Many studies have used these fluxes to derive the gas-phase metallicity of the galaxies by applying the so-called strong-line methods. However, the

The Stellar Observations Network Group (SONG) is an internationalnetwork project aiming to place eight 1 m robotic telescopes around the globe,with the primary objectives of studying stellar oscillations and planetsusing ultra-precision radial velocity measurements.The prototype of SONG will be installed and running at the Observatoriodel Teide by

OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is to take a series of 39 s exposures in the g band of a 1 deg2 of sky lasting 2 h using the OmegaCAM wide field imager on the VLT Survey Telescope (VST). We give an

In this Letter we report new evidence for a close three-galaxy interaction in the compact group of galaxies HCG 95. Deep optical imaging in the Johnson UBVRI bands and in narrowband H alpha have shown four long tidal tails emanating from the two disk galaxies as well as signs of transfer of material between one of the tidal tails and the elliptical
