Observations and Simulations of Fibrils and Mottles
Bart De Pontieu, Viggo H. Hansteen, Luc Rouppe van der Voort +2
With the recent advent of the Swedish 1-m Solar Telescope (SST), advanced image processing techniques, as well as numerical simulations that provide a more realistic view of the ch…
High Resolution Observations and Modeling of Dynamic Fibrils
B. De Pontieu, V. H. Hansteen, L. Rouppe van der Voort +2
We present unprecedented high resolution H-alpha observations, obtained with the Swedish 1-m Solar Telescope, that, for the first time, spatially and temporally resolve dynamic fib…
The Capabilities of the EISCAT Svalbard Radar for Inter-hemispheric Coordinated Studies
Tom Grydeland, Anja Strømme, Tony van Eyken +1
In this article we want to present the EISCAT Svalbard Radar (ESR) in some detail, as well as some of the instruments of interest for ionospheric and magnetospheric research that a…
Direct Observation of Coexistence of Ferromagnetism and Superconductivity in RuSr2(Gd0.7Ce0.3)2Cu2O10
S. Y. Chen, J. Shulman, Y. S. Wang +6
Recent reports of the detecting of ferromagnetism and superconductivity in ruthenium-cuprates have aroused great interest. Unfortunately, whether the two antagonistic phenomena coe…
Spectroscopic confirmation of a cluster of galaxies at z=1 in the field of the gravitational lens MG2016+112
G. Soucail, J. P. Kneib, A. O. Jaunsen +3
We present new optical data on the cluster AX J2019+1127 identified by the X-ray satellite ASCA at z\sim 1 (Hattori et al. 1997). The data suggest the presence of a high-redshift c…
Sharp k-space features in the order parameter within the interlayer pair-tunneling mechanism of high-T_c superconductivity
G. G. N. Angilella, R. Pucci, F. Siringo +1
We study the k-dependence of the gap function of a bilayer superconductor, using standard mean-field techniques applied to a 2D extended Hubbard model, in the presence of coherent…
