Cosmological Zoom-In Simulations of Milky Way Host Mass Dark Matter Halos with a Blue-Tilted Primordial Power Spectrum
Jianhao Wu, Tsang Keung Chan, Victor J. Forouhar Moreno
Recent observations from the James Webb Space Telescope revealed a surprisingly large number of galaxies at high redshift, challenging the standard Lambda Cold Dark Matter cosmolog…
A halo model for cosmological Lyman-limit systems
Tom Theuns, TK Chan
We present an analytical model for cosmological Lyman-limit systems (LLSs) that successfully reproduces the observed evolution of the mean free path (L) of ionizing photons. The ev…
The impact and response of minihalos and the inter-halo medium on cosmic reionization
Tsang Keung Chan, Alejandro Benitez-Llambay, Tom Theuns +2
An ionization front (I-front) that propagates through an inhomogeneous medium is slowed down by self-shielding and recombinations. We perform cosmological radiation hydrodynamics s…
