J/ApJ/640/768      IR sources in the NGC 5291 system             (Higdon+, 2006)

First detection of PAHs and warm molecular hydrogen in tidal dwarf galaxies. Higdon S.J., Higdon J.L., Marshall J. <Astrophys. J., 640, 768-783 (2006)> =2006ApJ...640..768H
ADC_Keywords: Galaxies, IR Keywords: galaxies: dwarf - galaxies: formation - galaxies: individual (NGC 5291, NGC 5291 S, NGC 5291 N) - galaxies: interactions - infrared: galaxies Abstract: We observed two faint tidal dwarf galaxies (TDGs), NGC 5291 N and NGC 5291 S, with the Infrared Spectrograph on the Spitzer Space Telescope. We detect strong polycyclic aromatic hydrocarbon (PAH) emission at 6.2, 7.7, 8.6, 11.3, 12.6, and 16.5µm, which match models of groups of 100 carbon atoms with an equal mixture of neutral and ionized PAHs. Description: IRS observations were taken of both TDG-N and TDG-S. The IRS low-resolution data were obtained with Short-Low (IRS-SL), which operates between 5.2 and 7.7µm (IRS-SL2) and 7.4-14.5µm (IRS-SL1). IRAC data in all four bands were acquired using a two-point map centered on NGC 5291 (13:47:23.00-30:25:30.0 [J2000.0]).

Note (1): Note on [HHM2006], defined as follows: b = Source is outside HI ring. c = Galaxy 435 (Malphrus et al. 1997AJ....114.1427M; Richter 1984A&AS...58..131R). d = 16 pixel diameter aperture. e = TDG-N, source K09.09 (CTS K09.09 in Simbad, Pena et al. 1991A&A...251..417P). f = TDG-S; the tail is source G ([LHC79] G in Simbad) in Longmore et al. (1979MNRAS.188..285L). g = Magnitude of the autoflux density as source is extended beyond 16 pixel diameter aperture. Note the aperture correction for an infinitely extended source has not been applied. The correction factors listed in the Spitzer Observers Manual are 0.94, 0.94, 0.63, 0.69 at [3.6], [4.5], [5.8], and [8.0], respectively. h = Seashell. i = NGC 5291. Note (2): Identification from Longmore et al. (1979MNRAS.188..285L) and Malphrus et al. (1997AJ....114.1427M): [LHC79] A or [LHC79] N in Simbad Note (3): Identification from Duc & Mirabel (1998A&A...333..813D); in Simbad: [DM98] Knot a ; [DM98] A ; [DM98] N . Note (4): Classification from the SED match, defined as follows: TDG = candidate tidal dwarf galaxy; SF = reasonable fit to TDG-N, star-forming region; N = "notched" SED, but poor match to TDG-N; E = elliptical; E* = elliptical/foreground star; S0 = S0; S0* = S0/foreground star; AGN = active galactic nuclei; AGN? = not a simple power law.
