Sasmirala Individual Information for Mrk 590

Description

Mrk 590 is a spiral galaxy at a redshift of z = 0.0264 (D ~ 107 Mpc) with a Sy 1.0 nucleus [veron-cetty_catalogue_2010] and an extended NLR (diameter~ 1.5arcsec ~ 750 pc; PA~-5; [schmitt_hubble_2003]) and an unresolved radio core [schmitt_jet_2001]. It belongs to the nine-month BAT AGN sample. Since IRAS, the source was observed in the MIR with the MMT [maiolino_new_1995], with ISO/ISOCAM [ramos_almeida_mid-infrared_2007] and Spitzer/IRS (e.g., [dasyra_high-ionization_2008, weaver_mid-infrared_2010]) and MIPS. Mrk 590 appears compact in the MIPS 24 μm image, while the IRS LR staring mode spectrum shows silicate 10 and 108 μm emission, a weak PAH 11.3 μm feature and an emission peak at ~ 17 μm in νfν-space, i.e., the MIR SED seems AGN dominated. We observed Mrk 590 with VISIR in three narrow N-band filters in 2006 [horst_mid_2008, horst_mid-infrared_2009]. An unresolved MIR nucleus without any sign of host emission was detected in all images. Our reanalysis of the images provides nuclear fluxes consistent with [horst_mid_2008] and the Spitzer spectrophotometry. Note that the MMT and ISO photometric fluxes are ~ 50% higher than the more recent measurements, which is either caused by host emission outside of the central ~ 4arcsec ~ 2 kpc or a decrease of the nuclear flux over the last decade.

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.

Spitzer MIR images. Displayed are the inner 40 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 0.1% pixels with the highest intensity. The label in the bottom left states instrument and central wavelength of the filter in micron (I: IRAC, M: MIPS).

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.
