MHD Turbulence in Star-Forming Clouds
Mordecai-Mark Mac Low, Ralf Klessen, Fabian Heitsch
We review how supersonic turbulence can both prevent and promote the collapse of molecular clouds into stars. First we show that decaying turbulence cannot significantly delay coll…
Segregation of polydisperse granular media in the presence of a temperature gradient
S. Luding, O. Strauss, S. McNamara
Granular media are examined with the focus on polydisperse mixtures in the presence of two localized heat-baths. If the two driving energies are similar, the large particles prefer…
A Simple Method to Mix Granular Materials
S. McNamara, S. Luding
We show that a mixture of two species of granular particles with equal sizes but differing densities can be either segregated or mixed by adjusting the granular temperature gradien…
RX J1624.9+7554: A new X-ray transient AGN
D. Grupe, H. -C. Thomas, K. M. Leighly
We report the discovery of a new X-ray transient AGN, RX J1624.9+7554. This object appeared to be bright in the ROSAT All-Sky Survey, but had turned off in two pointed observations…
