Proposal Title: Properties of the ISM of a sample of the most isolated galaxies: Atomic gas
content.
ABSTRACT:
We are studying a large sample of completely isolated galaxies in order to analyze star formation and galaxy
evolution independent of exterior in uences. Our source is the Catalog of Isolated Galaxies and our sample
contains 760 galaxies for which we are building a multiwavelength database. We already collected old and new
unpublished optical and FIR data which enabled us to study luminosities and global properties of the sample, and
we are currently obtaining/compiling HI, CO and H data. We searched the NED and the HI catalog Huchtmeier
and Richter (1989) nding available HI spectra for half of the sample. Among the rest, we are currently observing
 60 galaxies at the Green Bank Telescope. We have splitted the rest of the sample between Arecibo and other
radiotelescopes according to sensitivity and declination, in order to complete the HI database of the full sample.
Here we ask for observing time to observe 62 galaxies with the Arecibo radio telescope.
