Sharper Image of Galaxy with VLASS
The sharpest radio view ever made of such a large portion of the sky! This galaxy, observed by the new VLA Sky Survey, resides near the constellation Draco in the northern hemisphere. No sources are detected at the radio galaxy’s position in optical wavelengths (center right panel), but there is a hint of the central galaxy at infrared wavelengths (bottom right panel). The top right panel shows the radio source from our previous (NVSS) survey, but the resolution was too faint to work out the details. However, our new survey has the resolution to reveal the distinct features of the radio lobes from a supermassive black hole found at the heart of most galaxies!
