The LOFAR Two-metre Sky Survey (LoTSS) has released its second data release (DR2), containing over 4 million radio sources. Many of these are galaxies harbouring an active super-massive black hole in their core. The visualisation on the right shows the position in space and distance relative to us for sources to which the distance has been determined. The distances come from efforts within the collaborations and photometric redshifts from publicly available DESI DR9 catalogues. Positions of approximately 2.4 million radio sources of LoTSS DR2 are shown here. The wireframe half-sphere represents the sky above LOFAR and the red points serve to illustrate the parts of the sky covered. Read more in the official press release
