High-resolution spectra (range 655-675 nm) are presented of the pre-main sequence triple system UX Tau. Favorable seeing conditions allowed detection of the...

Dwarf irregular galaxies (dIrrs) are the smallest stellar systems with extended H i discs. The study of the kinematics of such discs is a powerful tool to...

The Liverpool Telescope is one of the world's premier facilities for time domain astronomy. The time domain landscape is set to radically change in the coming...

The search for new global scaling relations linking the physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially...

Using a representative sample of 14 star-forming dwarf galaxies in the local Universe, we show the existence of a spaxel-to-spaxel anticorrelation between the...

The way in which the evaluation of any moment of the mass distribution, as given by the Zeldovich (1970) approximation, may be reduced to the computation of an...

The study of the stellar content and physics of the ionized gas in local high-mass star-forming regions is specially important for better understanding...

Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use Sloan Digital Sky Survey data to determine the...

Tadpole galaxies, with a bright peripheral clump on a faint tail, are morphological types unusual in the nearby universe but very common early on. Low mass...
