Galactic Mass and Anisotropy Profile with Halo K-Giant and Blue Horizontal Branch Stars from LAMOST/SDSS and Gaia
A major uncertainty in the determination of the mass profile of the Milky Way using stellar kinematics is the poorly determined anisotropy parameter, beta = 1 - ( ( (sigma_theta)**2 + (sigma_phi)**2 )...

Bridging geometric and wave optics through the complex plane
Much of the lensing effects in astrophysics can be adequately described using geometric optics, where light from a point source can be split into multiple magnified images. In coherent sources, such ...
