The ancient place-name for the village of Torredonjimeno
El nombre antiguo (pre-romano o romano) de “Torredonjimeno” (Jaén) sigue siendo objeto de disputa. Para unos sería “Tucci Vetus” y para otros “Abra”. Por otra parte se le atribuye el nombre de “Ossaria” en época visigótica. Finalmente, en el propio “Torredonjimeno” y en general en la provincia de Jaén se da por cierto que su nombre fue “Tosiria”, del que deriva el localicio “Tosiriano” de uso generalizado. En este trabajo tratamos de arrojar luz a este problema toponímico.The ancient (pre-roman or roman) place-name for the village of “Torredonjimeno” (Jaen, in the South of Spain) is actually disputed. For some scholars it would be “Tucci Vetus”, for some others “Abra”. Further on, during the Visigothic time, it would be named “Ossaria”. Finally, in Torredonjimeno and generally speaking, in Jaen province, the names used nowadays are “Tosiria” for the village and “Tosirian” for its inhabitants. The present research work is aimed to bring some light into the problem
Revisiting the location and environment of the central engine in NGC1068
We revisit in this paper the location of the various components observed in
the AGN of NGC1068. Discrepancies between previously published studies are
explained, and a new measurement for the absolute location of the K-band
emission peak is provided. It is found to be consistent with the position of
the central engine as derived by Gallimore (1997), Capetti (1997) and Kishimoto
(1999). A series of map overlays is then presented and discussed. Model
predictions of dusty tori show that the nuclear unresolved NIR-MIR emission is
compatible with a broad range of models: the nuclear SED alone does not
strongly constrain the torus geometry, while placing reasonable constraints on
its size and thickness. The extended MIR emission observed within the ionizing
cone is shown to be well explained by the presence of optically thick dust
clouds exposed to the central engine radiation and having a small covering
factor. Conversely, a distribution of diffuse dust particles within the
ionizing cone is discarded. A simple model for the H2 and CO emission observed
perpendicularly to the axis of the ionizing cone is proposed. We show that a
slight tilt between the molecular disc and the Compton thick central absorber
naturally reproduces the observed distribution of H2 of CO emission.Comment: 17 pages, 11 figures, revised version for A&
