| dc.description.abstract | We present Spitzer Space Telescope InfraRed Array Camera (IRAC) and Multiband Imaging Photometer (MIPS) observations of the elliptical galaxy NGC 315. After removal of the host galaxy's stellar emission, we detected for the first time an infrared-red nucleus in NGC 315. We measured the spectral energy distribution (SED) for this active nucleus with a wavelength range from radio to X-ray, and obtained a bolometric luminosity of Lbol ≈ 1.9 × 1043 ergs s−1, corresponding to an extremely low Eddington ratio L/LEdd of 4.97 × 10−4. Our results confirm that the physical nature of the nucleus of NGC 315 is a low-luminosity AGN, consistent with recent optical and Chandra X-ray observations. | en_US |
