J/A+A/507/713      Galaxies with strong PAH emission         (Haas+, 2009)

Polycyclic aromatic hydrocarbon selected galaxies. Haas M., Leipski C., Siebenmorgen R., Meusinger H., Drass H., Chini R. <Astron. Astrophys., 507, 713-721 (2009)> =2009A&A...507..713H
ADC_Keywords: Galaxies, IR ; Photometry, infrared ; Interstellar medium Keywords: galaxies: active - infrared: galaxies Abstract: This is the fourth in a series of papers based on the ISOCAM Parallel Survey at 6.7um. While the first three papers have been devoted to active galactic nuclei (AGN), here we report on emission-line galaxies without AGN signatures in their optical spectra. Polycyclic aromatic hydrocarbon (PAH) emission has been found in both starbursts and modestly starforming galaxies, but the relation between starforming activity and PAH luminosity is still a matter of debate. The different correlation degrees could be caused by the variety of optical and far-infrared sample selection criteria. In order to obtain a census of the typical properties of PAH emitting galaxies, we here study moderately distant galaxies which have been selected by their PAH emission. Description: Combining the ISOCAM Parallel Survey at 6.7um with 2MASS we have colour-selected a sample of 120 candidates for strong PAH emission. We obtained optical and mid-infrared spectra of 75 and 19 sources, respectively, and analysed IRAS-ADDSCANs and available Spitzer 3.6-160um photometry. File Summary:

Note (1): LW2 zero magnitude corresponds to 90Jy, i.e. 0.9mJy corresponds to 12.5mag (Vega system). Note (2): Measured in the 1-2" wide slit, and expressed in 10-16erg/cm2/s/Å = 10-18W/2/nm. The uncertainties are ∼5-10%. Note (3): Negative EW values correspond to emission lines. Mean uncertainties are ∼10% Note (4): Mean uncertainties are ∼25% Note (5): Morphological appearance in SDSS images. Definitions are as follows: regular = regular sources are extended with >5" diameter. Regular sources have between face-on and intermediate inclination edge-on = edge-on sources extended with >5" diameter irregular = extended with >5" diameter compact = regular and < 5" diameter tail = irregular, but with bright connected tidal tail(s) double = two equally bright sources companion = another fainter source nearby (<10") group = at least two companions
