Universal bolometric corrections for AGN over 7 luminosity decades

Understand

The AGN bolometric correction is a key element to understand BH demographics and compute accurate BH accretion histories from AGN luminosities.

• However, current estimates still differ from each other by up to a factor of two to three, and rely on extrapolations at the lowest and highest luminosities.
• Here we revisit this fundamental issue presenting general hard X-ray ($K_{X}$) and optical ($K_{O}$) bolometric corrections, computed combining several AGN samples spanning the widest (about 7 dex) luminosity range ever used for this kind of studies.
• We analysed a total of $\sim 1000$ type 1 and type 2 AGN for which a dedicated SED-fitting has been carried out.
