From this, we can decide on an acceptable number of facet failures. ...

Next: Critical Frequencies and Gravitational Previous: Extragalactic Gravitational Wave Background . The number of binaries per frequency decade per solid angle from a separate stellar system (galaxy or cluster of galaxies) is . ... For example, for the Andromeda galaxy M31 ( rad, ) one gets . ... If the angular size of the galaxy is less than the angular resolution of the detector, the critical frequency is independent of the angular resolution, . ...

... We measured these galaxies individually, and they are distinguished in our list by the suffixes a, b, c,... in order of increasing J2000 right ascension. ... The first column contains the UGC catalog number, to which we have added lower-case suffixes a, b, c,\dots in order of increasing J2000 right ascension to distinguish individual galaxies in groups. ... The third column lists the degrees, arcminutes, and arcseconds of J2000 declination plus the rms uncertainty in arcseconds. ...

... In this talk, I will discuss a study of the effect of ionization on the low end of HI mass function. The existence of a large population of low mass galaxies follows from CDM theory. ... HIDEEP found no low HI column density galaxies. One possible explanation is that the disks are "frozen". ... We assume that galaxies are exposed to an ionizing background radiation, from a uniform quasar distribution. ... We find a gap in the average column densities around N H which drops to 10 17 cm -2 . ...
