Unlocking the Full Potential of Extragalactic Ly$\alpha$ through Its Polarization Properties

Marius B. Eide, Max Gronke, Mark Dijkstra +1

Lyman-$\alpha$ (Ly$\alpha$) is a powerful astrophysical probe. Not only is it ubiquitous at high redshifts, it is also a resonant line, making Ly$\alpha$ photons scatter. This scattering process…
