Force convergence in Monte Carlo Lyman-alpha radiative transfer
Joshua Kasiri, Aaron Smith, Kevin Lorinc +2
Monte Carlo radiative transfer (MCRT) is widely used to model Lyman-alpha (Lya) resonant-line transport, but convergence is difficult to assess in optically thick media where photo…
Lyman-alpha Pressure Strongly Enhances Pre-Supernova Feedback at Cosmic Dawn: The First Multi-Dimensional Lyman-alpha Radiation Hydrodynamics Simulations
Olof Nebrin, Aaron Smith, Garrelt Mellema +2
The dynamical role of Lyman- (Ly) radiation pressure feedback has been debated for nearly a century, with recent analytical and 1D numerical studies highlighting its potent…
Multi-Resonant-Line Radiative Transfer: Lyman-Alpha Fine Structure and Deuterium Coupling
Ethan Stace, Aaron Smith, Kevin Lorinc +1
Resonance lines encode rich information about astrophysical sources and their environments, yet fully analytic treatments of multi-line radiative transfer remain almost entirely un…
Core-wing transitions and the breakdown of diffusion in Lyman- radiative transfer
Kevin Lorinc, Aaron Smith, Olof Nebrin +1
The Lyman alpha (LyA) line of neutral hydrogen plays a central role in observations of star-forming galaxies. However, resonant scattering makes it difficult to directly interpret…
The THESAN project: Lyman-alpha intensity mapping of cosmic reionization
Mouza Almualla, Aaron Smith, Rahul Kannan +6
Line Intensity Mapping (LIM) has garnered attention as a powerful cosmological probe, with next-generation instruments such as SPHEREx preparing to map the evolution of large-scale…
Lyman-alpha resonant-line radiative transfer in expanding media
Aaron Smith, Kevin Lorinc, Olof Nebrin +1
The Lyman-alpha (LyA) line of atomic hydrogen encodes crucial information about both the intrinsic sources and surrounding environments of star-forming regions throughout the Unive…
