Derives analytical solutions and fitting formulae for Lyα spectra under cylindrical geometry including recoil and velocity gradients, validated against Monte Carlo simulations.
JWST spectra of six z=5-9 galaxies show low-ionization covering fractions of 0.2-0.9 and diverse kinematics including blueshifted outflows, indicating heterogeneous multiphase ISM.
A new fitting methodology applied to UV absorption data recovers radial trends in galactic wind velocities and mass-loading factors by constraining initial hot and cool phase parameters in a multiphase model.
Lyα radiation pressure mildly reduces gas-to-star conversion efficiency in dense high-redshift clusters while dominating the launch of rapid outflows.
LAEs at z=2.4-4.5 are smaller and more starbursting than typical SFGs, with Lyα strength correlating negatively with size and positively with Sersic index and recent SFR ratio.
Tadpole galaxies at high redshift commonly show extended, symmetric Lyα halos that are spatially offset from their UV continuum emission.
