(a) Paβ + continuum, (b) continuum, and (c) continuum-subtracted Paβ maps of Centaurus A. The maps have been smoothed with a Gaussian kernel of |${2{_{.}^{\prime\prime}}7}$| in sigma, and the color scales are given in units of |$\rm erg\, s^{-1}\, cm^{-2}\, arcsec^{-2}$|⁠. In panel (c), the contours show the Herschel 500 μm map from Auld et al. (2012), where the contour levels correspond to 0.10, 0.27, 0.72, 1.9, 5.2, 14, and |$37\rm \, mJy\, beam^{-1}$|⁠. The red squares, whose sizes are 30^″ × 45^″ and 60^″ × 90^″, indicate the northeast and the southwest regions where the Hα emission was detected by Santoro et al. (2016) and Keel et al. (2019), respectively. (Color online)
