Sasmirala Individual Information for 3C 459

Description

3C 459 is a FR II radio source identified with the infrared ultra-luminous, disturbed early-type galaxy LEDA 70899 [zheng_hst_1999] at a redshift of z = 0.2201 (D ~ 1125 Mpc). Its optical classification is controversial in the literature: it is classified as a type I AGN by [buttiglione_optical_2009, buttiglione_optical_2010], based on which [veron-cetty_catalogue_2010] presumably classified it as a Sy 1, while [tadhunter_optical_1993], [eracleous_doubled-peaked_1994], and [buchanan_radio-excess_2006] do not find evidence for broad lines and, thus, classify it as a type II object. Finally, [zheng_hst_1999] classify it as a LINER. Based on the presence of an intense starburst in 3C 459 [thomasson_3c459:_2003], we treat this object as an AGN/starburst composite. 3C 459 features an asymmetric supergalactic-scale biconical radio morphology along the east-west axis (PA~ 95^∘; [ulvestad_radio_1985, morganti_radio_1993]). The first successful MIR observations were performed with ISO/ISOCAM [siebenmorgen_isocam_2004]. This was then followed up with Spitzer/IRS and MIPS, where it appears unresolved. Our MIPS 24 μm photometry agrees with the value given in [dicken_origin_2008]. The IRS LR staring-mode spectrum was first published in [haas_spitzer_2005] and shows silicate absorption, strong PAH emission, and a red spectral slope in νF_ν-space, as expected for intense star formation. The VISIR SIC observation from 2010 has, to our knowledge, not yet been published. Unfortunately, 3C 459 remains undetected in the corresponding image. The derived upper limit on the nuclear SIC flux is consistent with the Spitzer spectrophotometry.

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.
