... INTRODUCTION M81 (NGC 3031) is a nearby galaxy (3.6 Mpc; Freedman et al. 1994), with well-defined spiralarms and a prominent bulge with a structure similar to that of M31. ...
... Its morphology is complex, with inner and outer spiralarms (Court'es et al. 1993), a dust lane and an optical/radio jet at a position angle (ё 150 o ; Cecil et al. 1992) close to that of the galaxy major axis. ...
... face-on orientation of M31 allows us to more easily determine the location of X-ray sources within (or outside of) spiralarms, the galactic bulge, or halo. 1 also Department of Physics and Astronomy, Tufts University, Medford, MA 02155 { 2 { M31 has been ...
... One can ask post-facto, how likely is it to find an interacting pair of massive spirals with spectacular tidal arms, well-centered near the mean position of the quasar images? ...
