Sasmirala Individual Information for NGC 5033
Description
NGC 5033 is an inclined spiral galaxy at a distance of D = 18.1 ± 7.4 Mpc (NED redshift-independent median) hosting an AGN, which has optically been classified either as a Sy 1.2, 1.5, 1.8 or 1.9 (see discussion in [trippe_multi-wavelength_2010]). It features a compact radio core with jet-like structure extending ~ 0.5arcsec ~ 45 pc to the east (PA~ 95∘; e.g., [ho_radio_2001]) and a one-sided very wide kiloparsec-scale [O III] cone towards PA~ 80∘ [mediavilla_asymmetrical_2005]. The first MIR observations of NGC 5033 were performed by [rieke_10_1978], but the nucleus remained undetected. [lawrence_observations_1985] report the first detection in N- and Q-band, followed by [devereux_spatial_1987], [edelson_broad-band_1987] and [maiolino_new_1995]. NGC 5033 was also observed with ISO [clavel_2.5-11_2000, ramos_almeida_mid-infrared_2007]. The first subarcsecond-resolution N-band image was obtained with Palomar 5 m/MIRLIN in 2000 [gorjian_10_2004]. The Spitzer/IRAC and MIPS images show an extended nucleus embedded within the spiral-like host emission. Our nuclear IRAC 5.8 and 8.0 μm fluxes are significantly lower than the values given in [gallimore_infrared_2010] but in agreement with the Spitzer/IRS LR mapping PBCD spectrum. The latter exhibits prominent PAH emission and a rather flat spectral slop in νFν-space (see also [dale_spitzer_2009, wu_spitzer/irs_2009, goulding_towards_2009, gallimore_infrared_2010, marble_aromatic_2010]). Thus, the arcsecond-scale MIR SED is dominated by significant star formation. The nuclear region of NGC 5033 was observed with Michelle in the N’ filter in 2008 [mason_nuclear_2012] and in the Si-5 filter in 2010 (this work). A compact nucleus was detected that is embedded within very weak emission extending in north-south direction. This extended emission coincides with the edges of the NLR cone and was detected in both images (diameter~ 2arcsec ~ 180 pc; PA~-5∘). In the sharper N’ image, the nucleus is possibly marginally resolved (FWHM(major axis)~ 0.42arcsec ~ 37 pc; PA~ 87∘). Additional deeper subarcsecond MIR imaging is required to confirm this morphology. Our nuclear photometry is consistent with [mason_nuclear_2012] and on average ~ 87% lower than the Spitzer spectrophotometry. The low spectral coverage does not permit characterisation of the nature of the nuclear MIR emission. We conclude that the MIR emission of the central ~ 350 pc in NGC 5033 is dominated by extended emission from star formation and the NLR.
