... The color composite image of Centaurus A reveals the lobes and jets emanating from the active galaxy?s central black hole. ... Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimetre wavelengths for the first time. ... Centaurus A hosts a very active and highly luminous central region, caused by the presence of a supermassive black hole is the source of strong radio and X-ray emission....

... Astrophysics Group . ... Exploring the Cosmic Dawn . ... Cosmic reionization corresponds to the epoch in which the first stars?а and black holes reionize the neutral intergalactic medium (IGM) that?аpervades the Universe following recombination, within a few hundred?аmillion years of the Big Bang. The epoch of reionization, and the?аpreceding ?dark ages? prior to the formation of the first stars,?аrepresent the last unexplored phases of cosmic evolution to be tested?аand explored. ...

... Our Galaxy . ... Stars . ... We all love bright and showy spiral galaxies! So much so, that we tend to overlook the elliptical galaxies which make up about 30% of the galaxies out there. Smaller than spiral galaxies, elliptical galaxies may be full of stellar living fossils, surviving virtually unchanged from an older cosmic era. ... Elliptical galaxies are smaller than spiral galaxies, roughly spherical and full of old stars. ... We know that galaxies interact and even collide. ...

... Image Quality of the VLT . Total Optical Control . First light for the ESO VLT unit telescope 1 occurred during the workshop. ... The image shown (Figure 1 ) here was obtained with the VLT on May 16, 1998, in red light (R band), i.e. while the mirror was still uncoated. ... In this diagram (FIgure 2), the measured image quality of the VLT UT1 astronomical images is plotted versus the ``seeing", as measured by the Seeing Monitor, a small telescope also located on top of the Paranal Mountain. ...
