Quasar Elemental Abundances at High Redshifts
M. Dietrich, F. Hamann, J. C. Shields +5
We examine rest-frame ultraviolet spectra of 70 high redshift quasars (z>3.5) to study the chemical enrichment history of the gas closely related to the quasars, and thereby estima…
The evolution of the Tully-Fisher relation of spiral galaxies
B. L. Ziegler, A. Boehm, K. J. Fricke +12
We present the B-band Tully-Fisher relation (TFR) of 60 late-type galaxies with redshifts 0.1-1. The galaxies were selected from the FORS Deep Field with a limiting magnitude of R=…
The Rapid Decay of the Optical Emission from GRB 980326 and its Possible Implications
Paul J. Groot, Titus J. Galama, Paul M. Vreeswijk
We report the discovery of the optical counterpart to GRB 980326. Its rapid optical decay can be characterized by a power law with exponent -2.10 +/- 0.13 and a constant underlying…
Discovery of an Optical Jet in the BL Lac Object 3C 371
K. Nilsson, J. Heidt, T. Pursimo +3
We have detected an optical jet in the BL Lac object 3C 371 that coincides with the radio jet in this object in the central few kpc. The most notable feature is a bright optical kn…
