PDS 144: The First Confirmed Herbig Ae - Herbig Ae Wide Binary
J. B. Hornbeck, C. A. Grady, M. D. Perrin +13
PDS 144 is a pair of Herbig Ae stars that are separated by 5.35" on the sky. It has previously been shown to have an A2Ve Herbig Ae star viewed at 83\circ inclination as its northe…
A Chandra Observation of the Nearby Sculptor Group Sd Galaxy NGC 7793
Thomas G. Pannuti, Eric M. Schlegel, Miroslav D. Filipovic +5
(Abridged) We conducted a Chandra ACIS observation of the nearby Sculptor Group Sd galaxy NGC 7793. At the assumed distance to NGC 7793 of 3.91 Mpc, the limiting unabsorbed luminos…
The COSPIX mission: focusing on the energetic and obscured Universe
P. Ferrando, A. Goldwurm, P. Laurent +57
Tracing the formation and evolution of all supermassive black holes, including the obscured ones, understanding how black holes influence their surroundings and how matter behaves…
Suzaku Detection of Diffuse Hard X-Ray Emission outside Vela X
Satoru Katsuda, Koji Mori, Robert Petre +9
Vela X is a large, 3x2 degrees, radio-emitting pulsar wind nebula (PWN) powered by the Vela pulsar in the Vela supernova remnant. Using four Suzaku/XIS observations pointed just ou…
Possible Charge-Exchange X-Ray Emission in the Cygnus Loop Detected with Suzaku
Satoru Katsuda, Hiroshi Tsunemi, Koji Mori +8
X-ray spectroscopic measurements of the Cygnus Loop supernova remnant indicate that metal abundances throughout most of the remnant's rim are depleted to about 0.2 times the solar…
The Chandra Carina Complex Project: Deciphering the Enigma of Carina's Diffuse X-ray Emission
Leisa K. Townsley, Patrick S. Broos, You-Hua Chu +11
We present a 1.42 square degree mosaic of diffuse X-ray emission in the Great Nebula in Carina from the Chandra X-ray Observatory Advanced CCD Imaging Spectrometer camera. After re…
