Sasmirala Individual Information for Mrk 1239

Description

Mrk 1239 is an elliptical galaxy at a redshift of z = 0.0199 (D ~88 Mpc) with an AGN classified as a Sy 1.5 and Sy 1n [veron-cetty_catalogue_2010]. This object has a steep radio spectrum with an unresolved core [ulvestad_radio_1995] and an extended NLR (diameter~ 10arcsec ~ 4.1 kpc; PA~ 11^∘; [mulchaey_emission-line_1996]). After IRAS, ground-based MIR observations of Mrk 1239 were performed by [maiolino_new_1995]. The first subarcsecond-resolution N-band imaging was done with Palomar 5 m/MIRLIN [gorjian_10_2004], and with ESO 3.6 m/TIMMI2 [raban_core_2008]. In the MIRLIN image, a compact MIR nucleus with extended emission with ~ 1arcsec to the north-west was detected, while in the TIMMI2 image elongated emission rather coinciding with the NLR was detected. Then, the object appears rather point-like in the Spitzer/IRAC images. The nuclear source is saturated in the PBCD version of the latter and thus not analysed (but see [gallimore_infrared_2010]). In addition, a Spitzer/IRS LR staring mode spectrum is of Mrk 1239 is available and shows silicate 10 and 18 μm emission, very weak PAH features and a blue spectral slope in νF_ν-space (see also [wu_spitzer/irs_2009, tommasin_spitzer-irs_2010, gallimore_infrared_2010]). Mrk 1239 was observed with VISIR in PAH2 in 2005 [haas_visir_2007], and with PAH2_2 and Q2 in 2006 [reunanen_vlt_2010]. The MIR nucleus appears compact in all images but possibly marginally resolved in the sharpest image (PAH2_2; FWHM~ 0.33arcsec; PA~ 85^∘). Our nuclear MIR photometry is on average ~ 10% higher than the literature values but mostly consistent with the IRS spectrum. Neither the structure of the MIRLIN nor of the TIMMI2 image are visible in the VISIR images. Therefore, it remains unclear, whether weak non-nuclear emission truly exists in Mrk 1239. Interestingly, the MIRLIN flux is at least 50% lower than all the other measurements. Note that the nucleus of Mrk 1239 was also been observed interferometrically with MIDI, where it remained essentially unresolved, implying a physical size of less than 7 pc for the MIR emitter [tristram_parsec-scale_2009, burtscher_diversity_2013].

SEDs

MIR SED. The description of the symbols in all the SED plots (where present) is the following: Grey crosses and solid lines mark the Spitzer/IRAC, MIPS and IRS data. The colour coding of the other symbols is as follows: green for COMICS, magenta for Michelle, blue for T-ReCS and red for VISIR data. Darker-coloured solid lines mark spectra of the corresponding instrument. The black filled circles mark the nuclear 12 and 18 micron continuum emission estimate from the data (where present). The ticks on the top axis mark positions of common MIR emission lines, while the light grey horizontal bars mark wavelength ranges affected by the silicate 10 and 18 micron features.
