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…
Quasar environments at 0.5 < z < 0.8
M. Wold, M. Lacy, P. B. Lilje +1
Over the past few years, we have been collecting data with the Nordic Optical Telescope (NOT) on the galaxy environments around active galactic nuclei (AGN). Here we present some r…
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…
