Galactic Centre Explorer

The Euclid Galactic Bulge Survey (left) compared to a ‘normal’ Euclid image (Abell 2764, right). The products of the main pipeline operated by the Science Ground Segment are used by most scientists in the Euclid Consortium. However, the main pipeline – primarily designed to detect, isolate, and measure distant galaxies – is not well suited for extremely crowded fields containing tens of millions of stars in one image. The vertical streaks are caused by extremely bright stars that saturate the pixels they fall on. The excess charge overflows into adjacent pixels above and below, which in turn become saturated and continue spreading the charge along the column, forming a vertical line. Read more
