| Description |
We propose a survey of PACS (at 70 and 160 micron) and SPIRE (at 250, 350 and 500 micron) imaging of a sample of 31 of the most turbulent and intensely star forming galaxies in the local universe to measure their characteristic dust temperatures, dust masses and total infrared luminosities. These galaxies, selected from the all sky SDSS survey as the most H(alpha) bright galaxies in the nearby universe, have high velocity dispersions but show signs of ordered disk rotation (Green et al 2010) and as a consequence have more similarities to high-redshift turbulent disk galaxies than dynamically-relaxed galaxies common to the local universe. But are these truly low redshift analogues of turbulent rotating disks or are they currently undergoing a starburst episode? While both galaxy types are expected to be bright in the infrared, the former would have a much lower characteristic dust temperature that can efficiently be measured with Herschel due to the proximity (0.06<z<0.25) of these galaxies. |
