X.Made available in DSpace on 2022-04-29T07:30:02Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-02-17; National Science Foundation; We report results of a wideband search for periodic gravitational waves from isolated neutron stars within the Orion spur towards both the inner and outer regions of our Galaxy. As gravitational waves interact very weakly with matter, the search is unimpeded by dust and conc...

B.Made available in DSpace on 2022-04-29T07:34:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-03-31; The LIGO detection of the gravitational wave transient GW150914, from the inspiral and merger of two black holes with masses 30M, suggests a population of binary black holes with relatively high mass. This observation implies that the stochastic gravitational-wave background from binary black holes, cre...
