Astronomers have used the world's largest and most sensitive low-frequency radio telescope array LOFAR (or Low-Frequency Array), to create the largest radio survey of the cosmos, revealing 13.7 million cosmic objects and events. These include jets erupting from feeding supermassive black holes, colliding galaxies, and supernova explosions that mark the deaths of massive stars and the births of unimaginably dense neutron stars.
The so-called LOFAR Two-meter Sky Survey (LoTSS-DR3) provides an impressive demonstration of how our view of the universe changes when astronomers switch from the wavelengths of light that our eyes have evolved to see to invisible radio waves. As such, LoTSS-DR3 could revolutionize our understanding of the massive jets and associated radio emissions that rip out from active supermassive black holes and our knowledge of how these outflows can shape entire surrounding galaxies.
