The eruption of magnetic flux tubes from the overshoot layer due to instability and the dynamics of their subsequent rise through the solar convection zone are...
Dynamics of Loop Quantum Gravity and Spin Foam Models in Three Dimensions
We present a rigorous regularization of Rovellis's generalized projection operator in canonical 2+1 gravity. This work establishes a clear-cut connection...
Dynamics of the Collimated Outflows of the PPN Hen 3-1475
Hen 3-1475 (IRAS 17423-1755) has recently been identified via ground-based and HST optical images as a bipolar proto-planetary nebula displaying a remarkable...
Dynamics of the Radio halo Cluster A2744: An Optical Study
We present the results of a dynamical analysis of the radio-halo cluster A2744 based on optical data. We find that this cluster is in an advanced merging phase...
The site selection for the future European Large Telescope (E-ELT) is a key issue within the European proposal funded by the EC, within the "ELT Design Study"...
