Descripción
We have used the package CLOUDPROPS (Rosolowsky & Leroy 2008) in
order to identify clouds, which are contained in data cubes of
molecular/Hα line emission, and extract their properties. The
molecular data cube is taken from the ALMA public archive and the
ionized hydrogen data cube was obtained with the Fabry-Perot
interferometer, GHαFaS, on the 4.2 m WHT in La Palma. In our study
of the overlap region of the Antennae galaxies we have identified two
populations of molecular clouds, above and below log M/M&sun;
= 6.75 (in agreement with Wei et al. 2012 who find the break in mass at
log M/M&sun; = 6.5) and two different populations of ionized
gas clouds; the break in the luminosity occurs near log L = 37.6 (see
Fig. 1). We have measured the masses, velocity dispersions and
luminosities of the clouds, and derived relation between them for each
population. Population II clouds (both molecular and ionized) tend to be
located in the most luminous regions, while population I clouds can be
found in the outskirts. This work will be published in Font et al.
(2013).

El objetivo básico del proyecto es investigar la evolución de las galaxias mediante el entendimiento de la interacción del medio interestelar y las estrellas. La técnica principal que utilizamos es la cinemática bidimensional de galaxias enteras observada por nuestro instrumento GHaFaS, un interferometro Fabry Perot en el telescopio William
