Sasmirala Individual Information for PKS 1417-19

Description

PKS 1417-19/LEDA 51213 is a radio-loud galaxy at a redshift of z = 0.1200 (D ~ 791 Mpc) with a Sy 1.5 nucleus [veron-cetty_catalogue_2010]. It possesses a biconical large-scale radio morphology with a jet along the north-east direction (PA~ 20; [antonucci_vla_1985]). PKS 1417-19 has not been detected with IRAS, and no Spitzer observations are available. It appears as a point source in the WISE images. [van_der_wolk_dust_2010] observed this object with VISIR in the broad SIC filter in 2006 and weakly detected a compact nucleus. The emission is possibly extended (FWHM(major axis)~ 0.5arcsec ~ 1.2 kpc; PA~ 97) perpendicular to the jet axis. However, at least a second epoch of deeper subarcsecond MIR imaging is required to verify this extension. The nuclear MIR data alone is insufficient for any conclusion about its nature but [van_der_wolk_dust_2010] attribute a large amount of the nuclear MIR emission to thermal 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.

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.
