Sasmirala Individual Information for 3C 93

Description

3C 93 is a radio-loud quasar with an optical Sy 1.0 classification [veron-cetty_catalogue_2010] at a redshift of z = 0.3571 (D ~ 1967 Mpc) and thus the most distant object in the AGN MIR atlas. It features symmetric biconical radio lobes on supergalactic scales in the north-east and south-west directions but no clear detections of collimated jets (PA~ 45^∘; FR II; e.g., [price_vla_1993, bogers_high_1994]). No Spitzer data are available for 3C 93, and it appears as a faint point source in the WISE images. This object was observed with VISIR in the broad SIC filter in 2006 but remained undetected by [van_der_wolk_dust_2010]. Our derived upper limit on the MIR flux is two times higher than theirs. However, the WISE band 3 (~ 12 μm) flux is lower than both, and, thus, is used as an upper limit for the estimate for the nuclear 12 μm continuum emission of 3C 93.

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.
