J/ApJ/707/890           IR properties of E and S0 galaxies         (Temi+, 2009)

Spitzer observations of passive and star-forming early-type galaxies: an infrared color-color sequence. Temi P., Brighenti F., Mathews W.G. <Astrophys. J., 707, 890-902 (2009)> =2009ApJ...707..890T
ADC_Keywords: Galaxies, IR ; Photometry, infrared Keywords: galaxies: elliptical and lenticular, cD - galaxies: ISM - infrared: galaxies - infrared: ISM Abstract: We describe the infrared properties of a large sample of early-type galaxies, comparing data from the Spitzer archive with Ks-band emission from the Two Micron All Sky Survey. While most representations of this data result in correlations with large scatter, we find a remarkably tight relation among colors formed by ratios of luminosities in Spitzer-Multiband Imaging Photometer bands (24, 70, and 160um) and the Ks band. Remarkably, this correlation among E and S0 galaxies follows that of nearby normal galaxies of all morphological types. Description: The FIR data presented here were obtained with the Multiband Imaging Photometer (MIPS) onboard the Spitzer Space Telescope in three wavebands centered at 24, 70, and 160um. These data, collected from the Spitzer public archive, do not form a homogeneous and uniform data set in terms of image depth and observing mode. Column 2 of Table 1 lists the program identification (ID) and principal investigator (PI) for the various original Spitzer observing programs from which our sample galaxies are selected.

Note (1): De Vaucouleurs numerical type, T correspondence with the Hubble type is defined in RC2 (Cat. VII/112). Data values are taken from the HyperLeda Database (Paturel et al. 2003, Cat. VII/237). Note (2): When available, distances are taken from Tonry et al. 2001ApJ...546..681T, otherwise they are from the NASA Extragalactic Database (NED) and corrected for H0=70km/s/Mpc. Note (3): Luminosities in the Ks band, LKs, have been derived using the flux density FKs published by the 2MASS survey, Skrutskie et al. 2006, Cat. VII/233. Note (4): The neutral hydrogen masses, MHI are taken from these publications: Morganti et al. 2006MNRAS.371..157M; Sage & Welch 2006ApJ...644..850S; di Serego Alighieri et al. 2007A&A...474..851D; Roberts et al. 1991ApJS...75..751R; Huchtmeier (1994A&A...286..389H); Huchtmeier et al.

Note (6): In this paper Lλ represents λLλ in erg/s. This differs from our previous notation in which Lλ represented the Spitzer band width multiplied by the specific luminosity.
