Abstract:
We present the properties of the first 250 µm blind sample of
nearby galaxies (15<D<46Mpc) containing 42 objects from the Herschel
Astrophysical Terahertz Large Area Survey. Herschel's sensitivity
probes the faint end of the dust luminosity function for the first
time, spanning a range of stellar mass (7.4<M*<11.3log10M☉),
star formation activity (-11.8<SSFR←8.9log10yr-1), gas fraction
(3-96 per cent), and colour (0.6<FUV-KS<7.0mag). The median cold
dust temperature is 14.6K, colder than in the Herschel Reference
Survey (18.5K) and Planck Early Release Compact Source Catalogue
(17.7K). The mean dust-to-stellar mass ratio in our sample is higher
than these surveys by factors of 3.7 and 1.8, with a dust mass volume
density of (3.7±0.7)x105M☉/Mpc3. Counter-intuitively, we
find that the more dust rich a galaxy, the lower its UV attenuation.
Over half of our dust-selected sample are very blue in FUV-KS
colour, with irregular and/or highly flocculent morphology; these
galaxies account for only 6 per cent of the sample's stellar mass but
contain over 35 per cent of the dust mass. They are the most actively
star-forming galaxies in the sample, with the highest gas fractions
and lowest UV attenuation. They also appear to be in an early stage of
converting their gas into stars, providing valuable insights into the
chemical evolution of young galaxies.
Description:
Observations for H-ATLAS were carried out in parallel mode at 100 and
160um with the Photodetector Array Camera and Spectrometer (PACS) and
at 250, 350 and 500um with the Spectral and Photometric Imaging
REceiver (SPIRE) instruments on board Herschel.
A sample of 42 galaxies was assembled from the H-ATLAS Phase-1
Version-3 catalogue in the distance range 15<D<46Mpc. We wished
to sample a volume local enough that we retained sensitivity to the
lowest-mass and coldest sources, populations not previously well
studied, and our upper distance limit of 46Mpc serves this purpose
well.
