IPHAS is a deep, fully photometric H α survey of the northern Galactic plane carried out with the Isaac Newton telescope at La Palma. The IPHAS point source Hα...

The Local Group Census is a narrowband imaging survey aimed at cataloguing the emission-line populations in the galaxies of the Local Group. Data, which were...

It is well known that magnetic activity in late-type stars increases with increasing rotation rate. Using inversion techniques akin to medical imaging, the...

The discrepancy between abundances computed using optical recombination lines (ORLs) and collisionally excited lines (CELs) is a major, unresolved problem with...

The description of the Imaging Magnetograph eXperiment (IMaX) is presented in this contribution. This is a magnetograph which will fly by the end of 2006 on a...

We explore the behaviour of the most popular spectroscopic absorption features in the optical region as a function of the initial mass function (IMF), while...

Dwarf galaxies tend to have a large spread in metal abundances and overall lower metallicites than large Spiral or Elliptical ones. Here we propose that if all...
