Luminous Compact Blue Galaxies (LCBGs) are high surface brightness starburst galaxies bluer than a typical SBc and with typical luminosities ≈ L ⋆, which are undergoing a major burst of star formation. LCBGs are the closest counterparts to the large population of starburst galaxies observed at high redshift, including Lyman-break galaxies at z ≈ 2

Solar magnetic fields are usually extrapolated into the corona starting from photospheric mag-netic measurements that can suffer from significant uncertainties caused by the presence of unresolved fine structures due to a limited spatial resolution and by the limited polarimet-ric accuracy and spectral resolution. We investigate how these

We present a short summary of the activities developed by GUAIX, the Universidad Complutense de Madrid (UCM) Group of Extragalactic Astrophysics and Astronomical Instrumentation. At present we are focused in the development of data reduction pipelines for several future instruments for the Spanish 10m GTC (Gran Telescopio Canarias). The careful

The study of the evolution of the Tully-Fisher relation has raised some problems during the last years. The main difficulty is determining the required parameters of intermediate redshift galaxies. In the present work, the rotational velocities obtained from the widths of different optical lines using DEEP2 spectra are compared. The apparent
