Gravitational Waves from a Population of Galactic Neutron Stars †
The existence of a large number of asymmetric, rotating neutron stars, each individually emitting periodic or quasi-periodic gravitational waves in the frequency band around 100 Hz, raises the possibility of detecting their combined signals, by exploiting the amplitude modulation of the received waves as the antenna changes its orientation with respect to fixed stars. This modulation is directl...

متن کاملSearches for Gravitational Waves from Binary Neutron Stars: A Review
A new generation of observatories is looking for gravitational waves. These waves, emitted by highly relativistic systems, will open a new window for observation of the cosmos when they are detected. Among the most promising sources of gravitational waves for these observatories are compact binaries in the final minutes before coalescence. In this article, we review in brief interferometric sea...
متن کاملGamma-ray Bursts from Blast Waves around Galactic Neutron Stars
The remarkable isotropy of classical gamma-ray bursts (GRBs) sampled by the BATSE instrument on GRO (Meegan et al. 1992; Fishman et al. 1993) requires their sources to be located at cosmological distances, in an extended halo of the Galaxy, or in a more local distribution (<∼ 1 − 2 Kpc) which contrives to be almost isotropic about us. Many authors have attributed ”galactic” bursts to violent di...
متن کاملContinuous Gravitational Waves from Isolated Galactic Neutron Stars in the Advanced Detector Era
We consider a simulated population of isolated Galactic neutron stars. The rotational frequency of each neutron star evolves through a combination of electromagnetic and gravitational wave emission. The magnetic field strength dictates the dipolar emission, and the ellipticity (a measure of a neutron star’s deformation) dictates the gravitational wave emission. Through both analytic and numeric...
