Predicting the Scaling Relations between the Dark Matter Halo Mass and Observables from Generalised Profiles I: Kinematic Tracers
Andrew Sullivan, Chris Power, Connor Bottrell
We investigate the relationship between a dark matter halo's mass profile and measures of the velocity dispersion of kinematic tracers within its gravitational potential. By predic…
On turbulence for spacetimes with stable trapping
Gabriele Benomio, Alejandro Cárdenas-Avendaño, Frans Pretorius +1
Motivated by understanding the nonlinear gravitational dynamics of spacetimes admitting stably trapped null geodesics, such as ultracompact objects and black string solutions to ge…
Numerical Black Hole Solutions in Modified Gravity Theories: Axial Symmetry Case
Andrew Sullivan, Nicolás Yunes, Thomas P. Sotiriou
We extend a recently developed numerical code to obtain stationary, axisymmetric solutions that describe rotating black hole spacetimes in a wide class of modified theories of grav…
Advanced Datapath Synthesis using Graph Isomorphism
Cunxi Yu, Mihir Choudhury, Andrew Sullivan +1
This paper presents an advanced DAG-based algorithm for datapath synthesis that targets area minimization using logic-level resource sharing. The problem of identifying common spec…
Jet outbursts, non-thermal pressure and the AGN jet duty cycle
Andrew Sullivan, Ross J. Turner, Stanislav S. Shabala +2
We predict the non-thermal pressure (NTP) induced in the cores of galaxy clusters by kinetic jet feedback from an active galactic nucleus (AGN). We model a population of Fanaroff-R…
Collaboration by Mandate: How Shared Data Infrastructure Shapes Coordination and Control in U.S. Homelessness Services
Lingwei Cheng, Saerim Kim, Andrew Sullivan
When governments mandate collaboration, shared data systems can serve both as tools for coordination and instruments of control. This study examines U.S. homelessness service netwo…
