Lyman alpha emission in high-redshift galaxies
C. Tapken, I. Appenzeller, S. Noll +4
A significant fraction of the high-redshift galaxies show strong Lyman emission lines. For redshifts z>5, most known galaxies belong to this class. However, so far not much is know…
Lyman-alpha emission galaxies at a redshift of z = 5.7 in the FORS Deep Field
C. Tapken, I. Appenzeller, A. Gabasch +7
We present the results of a search for Lyman-alpha emission galaxies at z~ 5.7 in the FORS Deep Field. The objective of this study is to improve the faint end of the luminosity fun…
Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71. I. Simultaneous broadband observations during November 2003
L. Ostorero, S. J. Wagner, J. Gracia +6
Some intra-day variable, compact extra-galactic radio sources show brightness temperatures severely exceeding 10^{12} K, the limit set by catastrophic inverse-Compton (IC) cooling…
The evolution of the luminosity functions in the FORS Deep Field from low to high redshift: II. The red bands
A. Gabasch, U. Hopp, G. Feulner +12
We present the redshift evolution of the restframe galaxy luminosity function (LF) in the red r', i', and z' bands as derived from the FORS Deep Field (FDF). Using the deep and hom…
Internal kinematics of spiral galaxies in distant clusters. Part II. Observations and data analysis
K. Jaeger, B. L. Ziegler, A. Boehm +5
We have conducted an observing campaign with FORS at the ESO-VLT to explore the kinematical properties of spiral galaxies in distant galaxy clusters. Our main goal is to analyse tr…
2QZJ215454.3-305654: a radio-quiet BL Lac object or lineless QSO?
D. Londish, J. Heidt, B. J. Boyle +2
High signal-to-noise spectroscopy has established a redshift of z=0.494 for the source 2QZJ215454.3-305654, originally selected from the 2dF/6dF QSO Redshift Surveys as one of 45 c…
