1ES 1741+196: a BL Lacertae object in a triplet of interacting galaxies?
J. Heidt, K. Nilsson, J. W. Fried +2
We present subarcsecond resolution imaging and spectroscopy of the BL Lac object 1ES 1741+196 and neighboring galaxies. Based on 2-dimensional modelling, the host galaxy of 1ES 174…

The optical/IR counterpart of the 3 July 1998 gamma-ray burst and its evolution
A. J. Castro-Tirado, M. R. Zapatero-Osorio, J. Gorosabel +21
We imaged the X-ray error box of GRB 980703, beginning 22.5 hours after the gamma--ray event, in both the optical R and near-infrared H bands. A fading optical/IR object was detect…

Faint galaxies around quasars at z=1 and gravitational lensing of distant objects
J. W. Fried
Very deep imaging data of three optically luminous radio-loud quasars with redshifts between z=0.9 and z=1.36 are presented. The data are complete for galaxies down to R=26. There…
