Title : Global properties of ULIGs at different phases of merging and activity
Authors : J. Gracia, P. Planesas, L. Colina, L. Lara, A. Alberdi
Abstract :
Our team has obtained the molecular gas mass and the CO profile characteristics for over
ULIGs with the IRAM 30m telescope, allowing us to compile a large sample, of about 80
objects, for which homogeneous data is available. The sample covers in a similar way the different
phases of the merging process and the different types of nuclear activity found in ULIGs. Complementary
data (infrared, radio continuum) have been gathered from the available literature, again stressing the goal
of homogeneity in their measurement for the objects in the sample. Results on measured and derived
properties will be given for the different merging/activity sub-samples, as well as trends found for the
whole sample.
