... Ultraluminous X-ray sources (ULXs) are located in external galaxies, their X-ray luminosities (10 39 - 10 41 erg/s) are thousand times greater than those of brightest black holes in the Galaxy. ULXs may be supercritical accretion disks around black holes of stellar masses (~10 Solar masses) like that in SS433, or they may be a hypothetical intermediate-mass black holes (hundreds - thousands Solar masses) with standard accretion disks. ... 2) The ULX progenitors were ejected from the star clusters. ...

The "21-inch" (0.52 meter) Moore reflector celebrated its 50th year in 2005, just prior to retirement from its role as our primary research instrument. ... The primary telescope and its mounting were designed and constructed by the Louisville Astronomical Society between 1935 to 1955. The telescope is named for Walter L. Moore, who was responsible for coordinating its construction, and who tested and figured its primary mirror. ... It is presently stored at Moore Observatory. ...
