Cosmological dynamics of scalar field with non-minimal kinetic term
H. Kröger, G. Melkonyan, S. G. Rubin
We investigate dynamics of scalar field with non-minimal kinetic term. Nontrivial behavior of the field in the vicinity of singular points of kinetic term is observed. In particula…
High resolution 21 cm mapping of the Ursa Major Galactic cirrus: power spectra of the high-latitude HI gas
M. -A. Miville-Deschenes, G. Joncas, E. Falgarone +1
We present a power spectrum analysis of interferometric 21 cm observations of the Ursa Major high-latitude cirrus, obtained with the Dominion Radio Astrophysical Observatory (DRAO)…
Automatic Detection of Expanding HI Shells Using Artificial Neural Networks
Anik Daigle, Gilles Joncas, Marc Parizeau +1
The identification of expanding HI shells is difficult because of their variable morphological characteristics. The detection of HI bubbles on a global scale therefore never has be…
Nanoengineered Astronomical Optics
E. F. Borra, A. M. Ritcey, R. Bergamasco +5
We describe a technology for the fabrication of inexpensive and versatile mirrors through the use of a new type of nanoengineered optical material composed by the spreading of a se…
Gemini observations of Wolf-Rayet Stars in the Local Group Starburst Galaxy IC10
P. A. Crowther, L. Drissen, J. B. Abbott +2
We present Gemini-N GMOS and CFHT MOS spectroscopy of Wolf-Rayet candidates in the Local Group dwarf galaxy IC10 that were previously identified by Massey et al. and Royer et al. F…
Cosmology at Low Redshifts
Ermanno F. Borra
It is argued that it is far more cost effective to carry out some projects with medium-sized dedicated zenith telescopes rather than large steerable telescopes, freeing the later t…
