We present an XMM–Newton observation of the massive edge-on Sb galaxy NGC 2613. We discover that this galaxy contains a deeply embedded active nucleus with a 0.3–10 keV luminosity of 3.3 × 1040 erg s−1 and a line-of-sight absorption column of 1.2 × 1023 cm−2. Within the 25 mag arcsec−2 optical B-band isophote of the galaxy, we detect an additional four sources with an accumulated luminosity of 4.3 × 1039 erg s−1. The bulk of the unresolved X-ray emission spatially follows the near-infrared (NIR) K-band surface brightness distribution; the …
