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...
