Was there an early reionization component in our universe?
Pablo Villanueva-Domingo, Stefano Gariazzo, Nickolay Y. Gnedin +1
A deep understanding of the Epoch of Reionization is still missing in our knowledge of the universe. While future probes will allow us to test the precise evolution of the free ele…
Star Cluster Formation in Cosmological Simulations. II. Effects of Star Formation Efficiency and Stellar Feedback
Hui Li, Oleg Y. Gnedin, Nickolay Y. Gnedin
The implementation of star formation and stellar feedback in cosmological simulations plays a critical role in shaping galaxy properties. In the first paper of the series, we prese…
Warm Dark Matter and Cosmic Reionization
Pablo Villanueva-Domingo, Nickolay Y. Gnedin, Olga Mena
In models with dark matter made of particles with keV masses, such as a sterile neutrino, small-scale density perturbations are suppressed, delaying the period at which the lowest…
Baryonic effects in cosmic shear tomography: PCA parametrization and importance of extreme baryonic models
Irshad Mohammed, Nickolay Y. Gnedin
Baryonic effects are amongst the most severe systematics to the tomographic analysis of weak lensing data which is the principal probe in many future generations of cosmological su…
The physical origin of long gas depletion times in galaxies
Vadim A. Semenov, Andrey V. Kravtsov, Nickolay Y. Gnedin
We present a model that explains why galaxies form stars on a time scale significantly longer than the time scales of processes governing the evolution of interstellar gas. We show…
