2011/10/21
We present a near-infrared extinction map of a large region (approximately 2200 deg^2) covering the Orion, the Monoceros R2, the Rosette, and the Canis Major molecular clouds. We used robust and optim...
Discovery of a Companion at the L/T Transition with the Wide-field Infrared Survey Explorer
Discovery Companion Transition with Infrared Survey Explorer
2011/9/30
We report the discovery of a substellar companion to the nearby solar-type star HD 46588 (F7V, 17.9 pc, ~3 Gyr). HD 46588 B was found through a survey for common proper motion companions to nearby sta...
The Wide Field X-Ray Telescope (WFXT) is a medium-class mission designed to be 2-orders-of-magnitude more sensitive than any previous or planned X-ray mission for large area surveys and to match in s...
Demography of obscured and unobscured AGN: prospects for a Wide Field X-ray Telescope
unobscured AGN prospects Wide Field X-ray Telescope
2011/1/13
We discuss some of the main open issues in the evolution of Active Galactic Nuclei which can be solved by the sensitive, wide area surveys to be performed by the proposed Wide Field X-ray Telescope mi...
