Summary

[edit]
Description
English: This photograph shows an image of the Quasar HE 1013-2136 (center) and its surroundings, as obtained with the FORS2 multi-mode instrument at the 8.2-m VLT KUEYEN telescope in February 2001. A spectacular arc-like tidal tail stretches from the quasar towards south-east (lower-left) over a distance of more than 150,000 light-years. Another, shorter tidal tail towards the east-northeast is barely visible. Technical information: this image is based on an image that was obtained in the morning of February 26, 2001 with the FORS2 instrument on VLT KUEYEN. It is composed of eight exposures in the I-band filter (effective wavelength 768 nm; FWHM 138 nm), lasting a total of 32 min. The combined image has a FWHM of 0.6 arcsec. The field shown measures 33 x 33 arcsec 2, or 540,000 x 540,000 light-years 2 projected at the distance of the quasar; 1 pixel = 0.2 arcsec. North is up and East is left.
