Filamentary shell structures from the AAO/UKST Ha survey
Here we present the first results of a search for new optical supernova remnant candidates and other filamentary objects on films produced by the Anglo-Australian Observatory/UK Schmidt Telescope Há Survey. Sixty-one fields, or 26% of the Galactic plane survey fields, have been visually examined. This has resulted in the detection of four newlarge diameter filamentary structures, and the discov...
متن کاملPrimordial quadrupole-induced polarisation from filamentary structures and galaxy clusters
We present the first computation of the Cosmic Microwave Background (CMB) polarisation power spectrum from galaxy clusters and filaments using hydrodynamical simulations of large scale structure. We give the E and B mode power spectra of the CMB quadrupole induced polarisation between l ∼ 560 and 20000. We find that the contribution from warm ionised gas in filamentary structures dominates the ...
متن کاملA New Model for Filamentary Molecular Clouds
We develop a theory for filamentary molecular clouds including the effects of ordered magnetic fields, and external pressure. We first derive a new virial equation appropriate for filamentary clouds. By comparing with observational results collected from the literature, we find that the fields are likely helical. Secondly, we construct numerical, MHD models of filamentary clouds that agree with...
متن کاملNEW RCS Frame Connection in Structures
Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...
متن کاملMagnetic filamentary structures in the spectrum of kinematic dynamos in plasmas June 8 , 2009
Kinney et al [PPL 1,(1994)] have investigated plasma filamentary structure dynamics. More recently, Wilkin et al [Phys Rev Lett 99:134501,(2007)] have shown that kinetic energy spectrum of magnetic structures in small-scale dynamos, are predominantly fila-mentary. Kirilov et al [PRE (2009)] have shown that use of the boundary values of the mean-field isotropic helical turbulent α 2-dynamo, coul...
