... Exploring the physics of Type Ia supernovae through spectral analysis . ... Their progenitor scenario as well as the details of the explosion mechanism remain a mystery. ... It produces a supernova spectrum for a given luminosity, photospheric velocity, time since explosion and several elemental abundances. Tweaking these parameters to produce a spectrum that fits an observed spectrum is a complex, as of yet, manual task. ... The search space is large and complex. ...

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 .. ...
