Abstract:
We present Spitzer IRAC 3.6-8µm and Multiband Imaging Photometer
24µm point-source catalogs for M31 and 15 other mostly large,
star-forming galaxies at distances ∼3.5-14Mpc, including M51, M83,
M101, and NGC 6946. These catalogs contain ∼1 million sources
including ∼859000 in M31 and ∼116000 in the other galaxies. They were
created following the procedures described in Khan et al. (2015,
J/ApJS/219/42) through a combination of point-spread function (PSF)
fitting and aperture photometry. These data products constitute a
resource to improve our understanding of the IR-bright (3.6-24µm)
point-source populations in crowded extragalactic stellar fields and
to plan observations with the James Webb Space Telescope.
Description:
For M31, we used the IRAC 3.6, 4.5, 5.8, and 8um mosaics produced by
Mould+ (2008, J/ApJ/687/230) and the MIPS 24um mosaic produced by
Gordon+ (2006ApJ...638L..87G 2006ApJ...638L..87G). For the other galaxies, we used the
IRAC and MIPS mosaics produced by the Spitzer Infrared Nearby Galaxies
Survey (SINGS; Kennicutt+ 2003PASP..115..928K 2003PASP..115..928K) and the Local Volume
Legacy Survey (LVL; Dale+ 2009, J/ApJ/703/517). We utilize the full
mosaics available for each galaxy.
