Molecular clouds in the central 200 pc of the Galaxy (the Central Molecular Zone ) exhibit different (and more extreme) physical properties than those in the disk, yet because this is the closest galactic nucleus, detailed studies of this region can provide insight on galactic nuclei in general in the nearby universe. ... In this talk I will present a case study of one of the clouds - a dense and unusual cloud, GCM0.253+0.016 - also known as The Brick . ...
... Printed in U.S.A. THE STELLAR DISK THICKNESS OF LOW SURFACE BRIGHTNESS GALAXIES D. Bizyaev 1,2,3 and S. Kajsin 4 Received 2003 October 23; accepted 2004 June 9 ABSTRACT We present surface photometry results for a sample of 11 edge-on galaxies observed with the 6 m telescope at the Special Astrophysical Observatory, Russia. ... We find from a comparison of photometric scales that the stellar disks of LSB galaxies are thinner than those of high surface brightness ( HSB) galaxies. ... UGC 11301 .. ...
