NGC4319 & Mrk 205 Showing the Bridge!

About this image

Another attempt at imaging the bridge! The “bridge” associated with Halton Arp and NGC 4319 refers to a controversial luminous filament or stream of material that Arp claimed connected the spiral galaxy NGC 4319 (redshift z ≈ 0.005, relatively nearby at ~80 million light-years) to the quasar Markarian 205 (Mrk 205, much higher redshift z ≈ 0.07, implying ~1 billion light-years distant if cosmological). Arp discovered this apparent bridge in deep photographic observations using the 200-inch Hale Telescope at Palomar Observatory around 1971. He interpreted it as physical evidence of a real connection, supporting his non-cosmological redshift ideas (e.g., quasars ejected from galaxies, not at Hubble-law distances).
