Extended HI Rotation Curve of M31 using deep DRAO observations
Claude Carignan, Laurent Chemin, Tyler Foster
Carignan et al. (2006) recently presented an extended HI rotation curve (RC) of M31, using single dish observations from the 100m Effelsberg and Green Bank telescopes. These observ…
Identifying and Characterizing New Nearby White Dwarfs
John P. Subasavage, Todd J. Henry, Pierre Bergeron +3
How confident are we that all of the nearest white dwarfs (WDs) have been identified? In an effort to answer this question, we have begun an initiative to identify and characterize…
New Praesepe white dwarfs and the initial mass-final mass relation
P. D. Dobbie, R. Napiwotzki, M. R. Burleigh +6
We report the spectroscopic confirmation of four further white dwarf members of Praesepe. This brings the total number of confirmed white dwarf members to eleven making this the se…
Accurate determination of the mass distribution in spiral galaxies III. Fabry-Perot imaging spectroscopy of 6 spiral galaxies
S. Blais-Ouellette, P. Amram, C. Carignan +1
High resolution Fabry-Perot data of six spiral galaxies are presented. Those data extend the previous sample of spiral galaxies studied with high resolution 3D spectroscopy to earl…
Structural relaxations in electronically excited poly(para-phenylene)
Emilio Artacho, M. Rohlfing, M. Cote +3
Structural relaxations in electronically excited poly(para-phenylene) are studied using many-body perturbation theory and density-functional-theory methods. A sophisticated descrip…
Triggered massive-star formation at the border of the HII region Sh 104
L. Deharveng, B. Lefloch, A. Zavagno +4
We present millimetre-line imaging of the Galactic HII region Sh 104. We show that it is surrounded by a ring of molecular gas and dust. Four large molecular condensations are regu…
