The Narrow Line Seyfert 1 galaxy 1H 0323+342: A rosetta stone for the jet/disk paradigm (Tibolla)

Proposal Abstract

According to the standard lore, gamma-ray emission from blazars originates in jets, blazars show accretion rates far below the Eddington limit and the accretion flow forms a torus. The Narrow-Line Seyfert 1 galaxy 1H0323+342, member of a new class of gamma-ray emitting AGN, does not fit into this picture: it shows near-Eddington accretion rate from an optically thick disk, showing at the same time gamma-ray emission. Moreover, 1H0323+342 seems to represent a transitional case in which the inner disk heats up and blows up to a torus configuration, as the accretion rate goes down (or vice versa). Thus, 1H0323+342 is the best target among the four gamma-ray bright Narrow-Line Seyfert 1 galaxies for its brightness and for its variability: in order to be able to study the disk/jet coupling and overall which condition take to the emerging of the jet over the disk spectrum, it is mandatory to perform simultaneous multiwavelenth observations and among them the hard X-ray band is particularily relevant: this is the scope of this proposal. Integral observations will be a crucial point in the success of the multiwavelength campaign on 1H0323+342 that will shed light on this jet/disk paradigm.

Observation Strategy (Recommended by TAC)

Total observing time of 600 ks split in four observations of 150 ks using the standard 5x5 dither pattern centered on RA, Dec (J2000.0, in degrees) = 51.172, 34.179 (l,b = 155.727, -18.757 degrees). The four observations are to be separated each by at least one month.

Proposal grade: A
