A multi-wavelength study of the southern hotspot in 4C 74.26
Mary Erlund, Institute of Astronomy
4C 74.26 is the largest known radio quasar spanning 1.1 Mpc (projected distance) on the sky. We present new infrared, optical and X-ray data of its southern hotspot complex. These data confirm that 4C 74.26 has a 10 arcsecond offset between the X-ray and radio peak in this hotspot (the largest known to date). They also reveal a wealth of new detail giving us a unique oportunity to probe the hotspot structure and understand the physical processes at work there.
