Primordial star clusters at extreme magnification
Erik Zackrisson, Juan Gonzalez, Simon Eriksson +4
Gravitationally lensed galaxies with magnification ~10-100 are routinely detected at high redshifts, but magnifications significantly higher than this are hampered by a combination…
The Lyman-alpha signature of the first galaxies
Aaron Smith, Chalence Safranek-Shrader, Volker Bromm +1
We present the Cosmic Lyman- Transfer code (COLT), a massively parallel Monte-Carlo radiative transfer code, to simulate Lyman- (Ly) resonant scattering through neutral hy…
Star Formation in the First Galaxies - II: Clustered Star Formation and the Influence of Metal Line Cooling
Chalence Safranek-Shrader, Milos Milosavljevic, Volker Bromm
Population III stars are believed to have been more massive than typical stars today and to have formed in relative isolation. The thermodynamic impact of metals is expected to ind…
Star Formation in the First Galaxies I: Collapse Delayed by Lyman-Werner Radiation
Chalence Safranek-Shrader, Meghann Agarwal, Christoph Federrath +3
We investigate the process of metal-free star formation in the first galaxies with a high-resolution cosmological simulation. We consider the cosmologically motivated scenario in w…
Confined Population III Enrichment and the Prospects for Prompt Second-Generation Star Formation
Jeremy S. Ritter, Chalence Safranek-Shrader, Orly Gnat +2
It is widely recognized that nucleosynthetic output of the first, Population III supernovae was a catalyst defining the character of subsequent stellar generations. Most of the wor…
Fragmentation in the First Galaxies
Chalence Safranek-Shrader, Volker Bromm, Milos Milosavljevic
We study the gravitational fragmentation of cold accretion streams flowing into a typical first galaxy. We use a one-zone hydrodynamical model to examine the thermal evolution of t…
