During the last decade a third window for ground-based astronomy was opened and high energy astrophysics now enables studies up to photon energies of 100 TeV. A wide range of objects were discovered to emit significant amounts of energy in the high-energy gamma-ray regime, including star-forming regions, pulsars, supernova remnants, massive binaries, the diffuse interstellar medium, the Galactic Centre, AGN, etc. ...
... 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 .. ...
