Sasmirala Individual Information for H1143-182
Description
H 1143-182 (z = 0.0329: D ~ 144 Mpc) was discovered as an AGN in X-rays by [remillard_discovery_1986]. It is classified as a Sy 1.5 [veron-cetty_catalogue_2010], and belongs to the 9 month BAT AGN sample. The host galaxy is the low-inclination spiral galaxy LEDA 88639. A Spitzer/IRS LR staring-mode spectrum is available and was analysed in [sargsyan_infrared_2011]. It shows silicate emission and only very weak PAH emission. In our three VISIR images, the nucleus of H 1143-182 appears very compact. The SIV filter image possesses the best S/N and also exhibits higher fluxes than those of the other filters, which suffer from low S/N. Therefore, the SIV filter flux is more reliable and also agrees with the IRS spectrum. The latter is used to compute the 12 μm nuclear continuum emission estimate corrected for the silicate 10 μm emission feature.

Images
Optical image (DSS, red filter). Displayed are the central 4 arcmin with North being up and East to the left. The colour scaling is linear with white corresponding to the median background (BG) and black to the 0.01% pixels with the highest intensity.
Subarcsecond-resolution MIR images sorted by increasing filter central wavelength. Displayed are the inner 4 arcsec with North being up and East to the left. The colour scaling is logarithmic with white corresponding to median BG and black to the 75% of the highest intensity of all images in units of sig_bg. The inset image (where present; either bottom or top right) shows the central arcsecond of the PSF from the calibrator star, scaled to match the science target. The labels in the bottom left state instrument and filter names (C: COMICS, M: Michelle, T: T-ReCS, V: VISIR).
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.
