On the relationship between dynamical masses from spectral features in emission and other mass estimators for a sample of local star-forming galaxies
We have obtained both virial and dynamical masses of a sample oflocal star forming galaxies from the UCM survey. The rotational curvesmeasured using the...
On the Relationship between Star Formation and Activity in Galaxies
This thesis is made of three main parts. In the first one a sample of 55 galaxies with an active nucleus (Seyfert 1, Seyfert2 and LINERs) is analysed; these...
On the sensitivity of the Halpha scattering polarization to chromospheric magnetism
A particularly interesting line for exploring the physical conditions of the quiet solar chromosphere is Halpha , but its intensity profile is magnetically...
On the structure of giant HII regions and HII galaxies
We review the structural properties of giant extragalactic HII regions and HII galaxies based on two dimensional hydrodynamic calculations, and propose an...
