The effects of different cooling and heating function models on a simulated analog of NGC300
David Robinson, Camille Avestruz, Nickolay Y. Gnedin +1
Gas cooling and heating rates are vital components of hydrodynamic simulations. However, they are computationally expensive to evaluate exactly with chemical networks or photoioniz…
Cosmic Ray Mediated Thermal Fronts in the Warm-Hot Circumgalactic Medium
Hanjue Zhu, Ellen G. Zweibel, Nickolay Y. Gnedin
We investigate the 1D plane-parallel front connecting the warm ( K) and hot ( K) phases of the circumgalactic medium (CGM), focusing on the influence of cosmic rays (CR…
On the universality of star formation efficiency in galaxies
Ava Polzin, Andrey V. Kravtsov, Vadim A. Semenov +1
We analyze high-resolution hydrodynamics simulations of an isolated disk dwarf galaxy with an explicit model for unresolved turbulence and turbulence-based star formation prescript…
On the minimum number of radiation field parameters to specify gas cooling and heating functions
David Robinson, Camille Avestruz, Nickolay Y. Gnedin
Fast and accurate approximations of gas cooling and heating functions are needed for hydrodynamic galaxy simulations. We use machine learning to analyze atomic gas cooling and heat…
On the Physical Nature of Ly Transmission Spikes in High Redshift Quasar Spectra
Hanjue Zhu, Nickolay Gnedin, Camille Avestruz
We investigate Lyman-alpha (Ly) transmission spikes at using synthetic quasar spectra from the ``Cosmic Reionization On Computers" simulations. We focus on under…
