Sasmirala Individual Information for Mrk 937
Description
Mrk 937 is a face-on spiral galaxy at a redshift of z = 0.0295 (D ~ 119 Mpc) with an AGN with optical Sy 1 classification [veron-cetty_catalogue_2010]. This object remained undetected with IRAS at 12 μm, and no Spitzer observations are available. We observed Mrk 937 in two narrow N-band filters in 2006 but did not detect any MIR emission either. Mrk 937 appears as a compact source with WISE with a 12 μm flux of 22 mJy, which is higher than our VISIR upper limits. This indicates that the total MIR emission of Mrk 937 might be dominated by non-AGN-related radiation.

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.
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.
