From the Top Down and Back Up Again: Star Cluster Structure from Hierarchical Star Formation
Michael Y. Grudić, Dávid Guszejnov, Philip F. Hopkins +4
Young massive star clusters spanning in mass have been observed to have similar surface brightness profiles. Recent hydrodynamical simulations of star cl…
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…
Modelling Jets, Tori and Flares in Pulsar Wind Nebulae
Oliver Porth, Rolf Buehler, Barbara Olmi +5
In this contribution we review the recent progress in the modeling of Pulsar Wind Nebulae (PWN). We start with a brief overview of the relevant physical processes in the magnetosph…
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…
Relativistic simulations of long-lived reverse shocks in stratified ejecta: the origin of flares in GRB afterglows
Astrid Lamberts, Frédéric Daigne
The X-ray light curves of the early afterglow phase from gamma-ray bursts present a puzzling variability, including flares. The origin of these flares is still debated, and often a…
