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…

Medium-resolution spectroscopy of galaxies with redshifts 2.3 < z < 3.5
D. Mehlert, C. Tapken, I. Appenzeller +3
Using FORS2 at the ESO VLT we obtained medium resolution (R ~ 2000) spectra of 12 galaxies with 2.37 < z < 3.40 in the FORS Deep Field. Two individual spectra with good S/N and a c…

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…
