Numerical simulations predict that gas accretion from the cosmic web drives star formation in disks galaxies. The process is more important in low mass haloes, therefore, when galaxies were low mass in the early universe, but also in dwarf galaxies of the local universe. The central role played by cosmic gas infall is as clear from numerical

We investigate the influence of galaxy-galaxy interactions on the star formation by studying a sample of almost 1500 of the nearest galaxies, all within a distance of 40 Mpc. We calculate the relative enhancement of the massive star formation rate (SFR), as measured from far-IR emission, and the specific star formation rate (SSFR), which is the

We test the capability of several methods to identify and characterise the warping of the stellar disc of our Galaxy in the Gaia era. We have developed a first kinematic model for the galactic warp and derived the analytical expressions for the force field of a warped Miyamoto- Nagai potential. We have generated realistic mock catalogues of OB, A

FRIDA (InFRared Imager and Dissector for the Adaptive optics system of GTC) is a near infrared, diffraction limited imager and integral field spectrograph that has been designed and is being built as a collaborative project between GTC partner institutions from México, Spain and the USA. FRIDA will operate with the adaptive optics system of GTC

Massive stars are crucial to understand the chemical and dynamical evolution of the Universe. Our knowledge of their physics at sub-SMC metallicities, dominant in the early Universe, is still in its infancy, due to the lack of proper observations and analyses. We have started a programme to observe stars in nearby galaxies with metallicities below

The Observatorio Astrofísico de Javalambre (OAJ) is a new astronomical facility located at the Sierra de Javalambre (Teruel, Spain) whose primary role will be to conduct all-sky astronomical surveys. The main OAJ facilities are two wide-field telescopes: the JST/T250, a 2.55 m telescope with a 3° diameter FoV, and the JAST/T80, a 0.83 m telescope
