Evicted? Possible Black Hole Found 2,600 Light Years from Home | W. M. Keck Observatory

November 23, 2014 By Sandy Eulitt

A Markarian galaxy is one which emits greater amounts of ultraviolet radiation than other galaxies. This one is a dwarf galaxy a mere 2600 light years away, practically down the street in astronomical terms. Despite its proximity and location in Ursa Major, it is doubtful that even my 28″ telescope SkyClops (TM) could see this, because it emits primarily in the ultraviolet spectrum, not the visible. It has a near-infrared magnitude of 12-13, which would be viewable if it were a visual magnitude. It would be an interesting exercise to see if I can resolve this. This region may not be above the horizon here in San Diego now, so I’ll have to add this to my list of objects to “shoot for” in a spring observing run.
