An image from the Karl G. Jansky Very Large Array of the Galaxy Hercules A (also known as 3C348) showing powerful synchrotron jets emerging from its core, the site of a supermassive black hole of 10 9 solar masses. The field center is RA= 16h51m8. 147s, Dec.= 4 ı 59 0 33.32 00 (2000), and the field of view is 3.3 2.4 arcmin. The image has been rotated clockwise by 36 degrees. The data set comprised 70 hours of observations acquired in 2010 and 2011 in bands from 4.2 to 9 GHz in all four array configurations with baselines from 36 m to 36 km. The image resolution is 0.3 00, corresponding to a linear scale of 800 pc at a distance of 730 Mpc, and the image contains about 10.7 Mpixels. The dynamic range is about 1200. The image has been reconstructed with a multiresolution CLEAN algorithm and self-calibration procedures described in Chapter 11. Color coded by intensity. Image from the NRAO, courtesy of B.
