Sasmirala Individual Information for Mrk 1014

Description

Mrk 1014 is a disturbed face-on ultra-luminous infrared spiral galaxy at a redshift of z = 0.1631 (D ~748 Mpc) with a radio-quiet quasar-type AGN optically classified as a Sy 1.5 [veron-cetty_catalogue_2010]. It features a very extended and complex NLR with two arcsecond (~ 5.4 kpc; PA~ 90; e.g., [bennert_size_2002]) coinciding with the radio emission structure (e.g., [leipski_radio_2006]). After the discovery of its MIR brightness through IRAS, Mrk 1014 was monitored with ground-based N-band photometry [neugebauer_continuum_1987, neugebauer_variability_1999]. It was also observed with ISO in different modes [rigopoulou_large_1999, sturm_mid-infrared_2002, haas_iso_2003] and Spitzer/IRAC and IRS. Mark 1014 appears point-like in all corresponding images, while the IRS LR staring-mode spectrum shows extremely weak silicate 10 μm emission, weak PAH features and a red slope in νFν-space (see also [armus_observations_2004, armus_observations_2007, farrah_high-resolution_2007, cao_mid-infrared_2008]). Thus, the MIR SED appears AGN-dominated. Mrk 1014 was observed with COMICS in the N11.7 filter in 2006 [imanishi_subaru_2011]. In the image, a marginally resolved and elongated MIR nucleus was detected (FWHM ~ 0.58arcsec ~ 1.9 pc; PA~ 63). However, at least a second epoch of subarcsecond MIR imaging is required to verify this extension. Our measured nuclear N11.7 flux is 25% higher than that of [imanishi_subaru_2011] but consistent with the previous N-band photometry and the Spitzer spectrophotometry. Therefore, we use the IRS spectrum to compute the nuclear 12 μm continuum emission estimate.

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.
