Measuring the dipole component of possible Galaxy-binary alignment in the mHz band
arXiv:2411.12961 · doi:10.1103/PhysRevD.110.123003
Abstract
We discuss the usability of the gravitational wave detector LISA for studying the orientational distribution of compact white dwarf binaries in the Galactic bulge. We pay special attention to measuring the dipole pattern of the distribution around the Galactic rotation axis. Based on our new formulation, which leverages the parity properties of the involved systems, we found that the apparent thickness of the bulge in the sky becomes critical for the dipole measurement. We also discuss the extra-Galactic studies for black hole binaries and neutron star binaries with BBO/DECIGO.
