NGC3147: a "true" Seyfert 2 without the broad-line region
S. Bianchi, A. Corral, F. Panessa +5
We report on simultaneous optical and X-ray observations of the Seyfert galaxy, NGC3147. The XMM-Newton spectrum shows that the source is unabsorbed in the X-rays ($N_H<5\times10^{…
New constraints on the membership of the T dwarf S Ori 70 in the sigma Orionis cluster
M. R. Zapatero Osorio, V. J. S. Bejar, G. Bihain +10
(Abridged) The nature of S Ori 70, a faint mid-T type object found towards the direction of the young sigma Orionis cluster, is still under debate. We intend to disentangle whether…
XMM-Newton observation of the deep minimum state of PG 2112+059: A spectrum dominated by reflection from the accretion disk?
N. Schartel, P. M. Rodriguez-Pascual, M. Santos-Lleo +5
We analyse a 75ks XMM-Newton observation of PG 2112+059 performed in November 2005 and compare it with a 15ks XMM-Newton observation taken in May 2003. PG 2112+059 was found in a d…
A PDR-Code Comparison Study
M. Roellig, N. P. Abel, T. Bell +21
We present a comparison between independent computer codes, modeling the physics and chemistry of interstellar photon dominated regions (PDRs). Our goal was to understand the mutua…
