Spatial fluctuations of the intergalactic temperature-density relation after hydrogen reionization
Laura C. Keating, Ewald Puchwein, Martin G. Haehnelt
The thermal state of the post-reionization IGM is sensitive to the timing of reionization and the nature of the ionizing sources. We have modelled here the thermal state of the IGM…
A tale of seven narrow spikes and a long trough: constraining the timing of the percolation of HII bubbles at the tail-end of reionization with ULAS J1120+0641
Jonathan Chardin, Martin G. haehnelt, Sarah E. I. Bosman +1
High-signal to noise observations of the Ly forest transmissivity in the z = 7.085 QSO ULAS J1120+0641 show seven narrow transmission spikes followed by a long 240 cMpc/h trough…
The effect of stellar and AGN feedback on the low redshift Lyman- forest in the Sherwood simulation suite
Fahad Nasir, James S. Bolton, Matteo Viel +4
We study the effect of different feedback prescriptions on the properties of the low redshift () Ly forest using a selection of hydrodynamical simulations drawn from t…
Importance of resolving the spectral support of beam-plasma instabilities in simulations
Mohamad Shalaby, Avery E. Broderick, Philip Chang +3
Many astrophysical plasmas are prone to beam-plasma instabilities. For relativistic and dilute beams, the {\it spectral} support of the beam-plasma instabilities is narrow, i.e., t…
Bow Ties in the Sky II: Searching for Gamma-ray Halos in the Fermi Sky Using Anisotropy
Paul Tiede, Avery E. Broderick, Mohamad Shalaby +4
Many-degree-scale gamma-ray halos are expected to surround extragalactic high-energy gamma ray sources. These arise from the inverse Compton emission of an intergalactic population…
SHARP: A Spatially Higher-order, Relativistic Particle-in-Cell Code
Mohamad Shalaby, Avery E. Broderick, Philip Chang +3
Numerical heating in particle-in-cell (PIC) codes currently precludes the accurate simulation of cold, relativistic plasma over long periods, severely limiting their applications i…
