On the Origin of Mass Segregation in NGC 3603
Xiaoying Pang, Eva K. Grebel, Richard J. Allison +5
We present deep Hubble Space Telescope/Wide Field and Planetary Camera 2 photometry of the young HD 97950 star cluster in the giant H {\sc ii} region NGC 3603. The data were obtain…
Electron acceleration in vacuum by ultrashort and tightly focused radially polarized laser pulses
Vincent Marceau, Alexandre April, Michel Piché
Exact closed-form solutions to Maxwell's equations are used to investigate electron acceleration driven by radially polarized laser beams in the nonparaxial and ultrashort pulse re…
A General Formulation for the Stiffness Matrix of Parallel Mechanisms
Cyril Quennouelle, Clément M. Gosselin
Starting from the definition of a stiffness matrix, the authors present a new formulation of the Cartesian stiffness matrix of parallel mechanisms. The proposed formulation is more…
Hydrogen volume densities in nearby galaxies I - an automated approach
J. S. Heiner, J. R. Sánchez-Gallego, L. Rousseau-Nepton +1
Using a simple model of photodissociated atomic hydrogen on a galactic scale, it is possible to derive total hydrogen volume densities. These densities, obtained through a combinat…
Remote creation of strong and coherent emissions in air with two-color ultrafast laser pulses
Jinping Yao, Guihua Li, Chenrui Jing +11
We experimentally demonstrate generation of strong narrow-bandwidth emissions with excellent coherent properties at ~391 nm and ~428 nm from molecular ions of nitrogen inside a fem…
Double Macdonald polynomials as the stable limit of Macdonald superpolynomials
O. Blondeau-Fournier, L. Lapointe, P. Mathieu
Macdonald superpolynomials provide a remarkably rich generalization of the usual Macdonald polynomials. The starting point of this work is the observation of a previously unnoticed…
