What observations are needed to advance our theoretical understanding of galaxy formation at high redshift?
H. Katz, R. S. Somerville, R. Schneider +98
Although significant progress has been made over recent decades, a comprehensive and predictive framework for galaxy formation remains elusive. Starting from cosmological initial c…
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 potentia…
Starbursts at Cosmic Dawn: Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6
Olof Nebrin
In the standard model of cosmology (CDM) the first stars, star clusters, and galaxies are expected to have formed in low-mass dark matter halos at high redshifts ($z \sim 6 - 30…
Core-wing transitions and the breakdown of diffusion in Lyman- radiative transfer
Kevin Lorinc, Aaron Smith, Olof Nebrin +1
The Lyman alpha (LyA) line of neutral hydrogen plays a central role in observations of star-forming galaxies. However, resonant scattering makes it difficult to directly interpret…
Multi-Resonant-Line Radiative Transfer: Lyman-Alpha Fine Structure and Deuterium Coupling
Ethan Stace, Aaron Smith, Kevin Lorinc +1
Resonance lines encode rich information about astrophysical sources and their environments, yet fully analytic treatments of multi-line radiative transfer remain almost entirely un…
Lyman-alpha resonant-line radiative transfer in expanding media
Aaron Smith, Kevin Lorinc, Olof Nebrin +1
The Lyman-alpha (LyA) line of atomic hydrogen encodes crucial information about both the intrinsic sources and surrounding environments of star-forming regions throughout the Unive…
Lyman- feedback prevails at Cosmic Dawn: Implications for the first galaxies, stars, and star clusters
Olof Nebrin, Aaron Smith, Kevin Lorinc +4
Radiation pressure from Lyman- (Ly) scattering is a potentially dominant form of early stellar feedback, capable of injecting up to more momentum into th…
Case A or Case B? The effective recombination coefficient in gas clouds of arbitrary optical thickness
Olof Nebrin
In calculations of the ionization state, one is often forced to choose between the Case A recombination coefficient (sum over recombinations to all hydrogen states) or…
Starbursts in low-mass haloes at Cosmic Dawn. I. The critical halo mass for star formation
Olof Nebrin, Sambit K. Giri, Garrelt Mellema
The first stars, galaxies, star clusters, and direct-collapse black holes are expected to have formed in low-mass () haloes at Cosmic Dawn ($z \sim…
Fuzzy Dark Matter at Cosmic Dawn: New 21-cm Constraints
Olof Nebrin, Raghunath Ghara, Garrelt Mellema
Potential small-scale discrepancies in the picture of galaxy formation painted by the CDM paradigm have led to considerations of modified dark matter models. One such dark matte…
