The ultracool eld dwarfs luminosity function from the Canada-France Brown Dwarf Survey
C. Reyle, P. Delorme, X. Delfosse +4
The Canada-France Brown Dwarf Survey is a wide eld survey for cool brown dwarfs conducted with the MegaCam camera on the CFHT telescope. Our objectives are to nd ultracool brown dw…
AGN-Starburst connection in NGC7582: Gemini near-infrared spectrograph integral field unit observations
Rogemar A. Riffel, Thaisa Storchi-Bergmann, Oli L. Dors +1
We analyse two-dimensional near-IR K-band spectra from the inner 660x315 pc^2 of the Seyfert galaxy NGC7582 obtained with the Gemini GNIRS IFU. The nucleus harbors an unresolved so…
Is J 133658.3-295105 a Radio Source at z >= 1.0 or at the Distance of M 83?
Horacio Dottori, Ruben J. Diaz, Damian Mast
We present Gemini optical imaging and spectroscopy of the radio source J 133658.3-295105. This source has been suggested to be the core of an FR II radio source with two detected l…
Stellar Velocity Profiles and Line-Strengths out to Four Effective Radii in the Early-Type Galaxy NGC 3379
A. Weijmans, M. Cappellari, P. T. de Zeeuw +6
We describe a new technique to measure stellar kinematics and line-strengths at large radii in nearby galaxies. Using the integral-field spectrograph SAURON as a 'photon-collector'…
SiO Outflow Signatures Toward Massive Young Stellar Objects with Linearly Distributed Methanol Masers
J. M. De Buizer, R. O. Redman, S. N. Longmore +2
Methanol masers are often found in linear distributions, and it has been hypothesized that these masers are tracing circumstellar accretion disks around young massive stars. Howeve…
Observing Strategies for the NICI Campaign to Directly Image Extrasolar Planets
Beth Biller, Etienne Artigau, Zahed Wahhaj +7
We discuss observing strategy for the Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope. NICI combines a number of techniques to attenuate starlight and s…
