NORI: a GPU-accelerated code for simulating self-gravitating and self-interacting dark matter
Oliver Zier, Ruediger Pakmor, Xuejian Shen +4
Self-interacting dark matter (SIDM) can form cores in dark matter haloes and later drive their gravothermal collapse, raising their central densities far above those of NFW haloes.…
A Novel Implementation of Self-Interacting Dark Matter in AREPO
Oliver Zier, Xuejian Shen, Vinh Tran +3
Self-interacting dark matter (SIDM) influences halo structure through collisional heat transport and may solve several small-scale puzzles in structure formation. SIDM creates ther…
The Lumina Project: Intergalactic Clumping and Recombination Sinks
Ali Sadain, Aaron Smith, Oliver Zier +10
Recombinations during the Epoch of Reionization are intrinsically inhomogeneous, with different regions of the intergalactic medium contributing unevenly depending on their density…
The Lumina Project: The Demographics of Active Galactic Nuclei from Quasars to Little Red Dots at
Xuejian Shen, Oliver Zier, Aaron Smith +16
High-redshift active galactic nuclei (AGN) serve as powerful probes of early black-hole growth, galaxy formation, and the evolving intergalactic medium (IGM). In this work, we use…
The Lumina Project: CMB Optical Depth Fluctuations from Patchy Reionization
Aaron Smith, Oliver Zier, Rahul Kannan +8
Patchy reionization couples the ionized-bubble morphology to the underlying density field, making the CMB Thomson optical depth sensitive to both the global ionization history and…
Introducing the Lumina project: large-volume radiation-hydrodynamic simulations of the epochs of hydrogen and helium reionization
Oliver Zier, Aaron Smith, Xuejian Shen +8
Understanding how galaxies and active galactic nuclei (AGN) jointly drive the reionization of the intergalactic medium (IGM) across cosmic time remains a major challenge in cosmolo…
Simulation-Based Prediction of Black Hole Spectra: From to
Chris Nagele, Julian H. Krolik, Rongrong Liu +2
It has long been thought that black hole accretion flows are driven by magnetohydrodynamic (MHD) turbulence, and there are now many general relativistic global simulations illustra…
Simulation-Based Prediction of Black Hole X-ray Spectra and Spectral Variability
Rongrong Liu, Chris Nagele, Julian H Krolik +2
Data derived from general relativistic magnetohydrodynamic simulations of accretion onto black holes can be used as input to a postprocessing scheme that predicts the radiated spec…
