Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact
G. P. Tozzi, H. Boehnhardt, L. Kolokolova +15
On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material ejected by the impact expa…
Establishing the nature of companion candidates to X-ray emitting late B-type stars
S. Hubrig, O. Marco, B. Stelzer +2
The most favored interpretation for the detection of X-ray emission from late B-type stars is that these stars have a yet undiscovered late-type companion (or an unbound nearby lat…
Dynamical modeling of the Deep Impact dust ejecta cloud
Tanyu Bonev, Nancy Ageorges, Stefano Bagnulo +17
The collision of Deep Impact with comet 9P/Tempel 1 generated a bright cloud of dust which dissipated during several days after the impact. The brightness variations of this cloud…
PSF reconstruction for NAOS-CONICA
Yann Clénet, Markus Kasper, Eric Gendron +7
Adaptive optics (AO) allows one to derive the point spread function (PSF) simultaneously to the science image, which is a major advantage in post-processing tasks such as astrometr…
Morphology of the coronal line region in active galactic nuclei
M. Almudena Prieto, Olivier Marco, Jack Gallimore
We present new images of the coronal line region, as traced by [Si VII] 2.48 \um, in some of the nearest Seyfert 2 galaxies. In each of these galaxies, the coronal line emission co…
A dual emission mechanism in Sgr A*/L' ?
Yann Clénet, Daniel Rouan, Damien Gratadour +4
We have collected in 2004 adaptive optics corrected L' images of the Galactic Center region with NAOS-CONICA at VLT. A strong variability was observed as well as a correlation betw…
