Prospects for gamma-ray observations of narrow-line Seyfert 1 galaxies with the Cherenkov Telescope Array II. gamma-gamma absorption in the broad-line region radiation fields

Popis výsledku v původním jazyce

Gamma-ray emitting narrow-line Seyfert 1 (gamma-NLS1) galaxies possibly harbour relatively low-mass black holes (10(6)-10(8) M-circle dot) accreting close to the Eddington limit, and share many characteristics with their sibling sources, flat-spectrum radio quasars. Although they have been detected in the MeV-GeV band with Fermi - LAT, they have never been seen in the very high energy band with current imaging atmospheric Cherenkov telescopes (IACTs). Thus, they are key targets for the next-generation IACT, the Cherenkov Telescope Array (CTA). In a previous work we selected, by means of extensive simulations, the best candidates for a prospective CTA detection (SBS 0846+513, PMN J0948+0022, and PKS 1502+036) taking into account the effects of both the intrinsic absorption (approximated with a cut-off at 30 GeV), and the extragalactic background light on the propagation of gamma-rays.n
