Refractive lensing of scintillating FRBs by sub-parsec cloudlets in the multi-phase CGM
Dylan L. Jow, Xiaohan Wu, Ue-Li Pen
We consider the refractive lensing effects of ionized cool () gas cloudlets in the circumgalactic medium (CGM) of galaxies. In particular, we discuss the comb…
Non-parametric Lagrangian biasing from the insights of neural nets
Xiaohan Wu, Julian B. Munoz, Daniel J. Eisenstein
We present a Lagrangian model of galaxy clustering bias in which we train a neural net using the local properties of the smoothed initial density field to predict the late-time mas…
A measurement of circumgalactic gas around nearby galaxies using fast radio bursts
Xiaohan Wu, Matthew McQuinn
The distribution of gas in the circumgalactic medium (CGM) of galaxies of all types is poorly constrained. Foreground CGMs contribute an extra amount to the dispersion measure (DM)…
A fully Lagrangian, non-parametric bias model for dark-matter halos
Xiaohan Wu, Julian B. Munoz, Daniel Eisenstein
We present a non-parametric Lagrangian biasing model and fit the ratio of the halo and mass densities at the field level using the mass-weighted halo field in the AbacusSummit simu…
The high-redshift tail of stellar reionization in LCDM is beyond the reach of the low- CMB
Xiaohan Wu, Matthew McQuinn, Daniel Eisenstein +1
The first generation (Pop-III) stars can ionize 1-10% of the universe by , when the metal-enriched (Pop-II) stars may contribute negligibly to the ionization. This low ioniza…
On the accuracy of common moment-based radiative transfer methods for simulating reionization
Xiaohan Wu, Matthew McQuinn, Daniel Eisenstein
Cosmological simulations of reionization often treat radiative transfer by solving for the monopole and dipoles of the intensity field and by making ansatz for the quadrupole momen…
