ArkenstoneBH. A model for high-specific energy black hole feedback in cosmological simulations

James M. Sullivan, Greg L. Bryan, Matthew C. Smith +6

AGN feedback is a key piece of galaxy evolution but is difficult to model due to its high specific energies, multiphase nature, and limited simulation resolutions. Arkenstone is a…

Gravitational Wave Measurement of the - Intrinsic Scatter at High Redshift

Cayenne Matt, Kayhan Gültekin, Gabriella Agazie +109

The observed GWB spectrum is higher in amplitude than model predictions by a factor of 2-3. Using a semi-analytic model, we evaluate the effect of a high-scatter supermassive black…

Parameter control for binary black hole initial data

Iago B. Mendes, Nils L. Vu, Oliver Long +2

When numerically solving Einstein's equations for binary black holes (BBH), we must find initial data on a three-dimensional spatial slice by solving constraint equations. The cons…

The SXS Collaboration's third catalog of binary black hole simulations

Mark A. Scheel, Michael Boyle, Keefe Mitman +56

We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…

Pulsar Cyclic Spectroscopy in the Partial-Deconvolution Regime: Benefits & Limitations

Jacob E. Turner, Timothy Dolch, Paul B. Demorest +5

We explore possible advantages of cyclic spectroscopy for observations of pulsars in instances where full cyclic deconvolution is not feasible. We compute cyclic merits and full-de…

"I Would Have Written My Code Differently'': Beginners Struggle to Understand LLM-Generated Code

Yangtian Zi, Luisa Li, Arjun Guha +2

Large language models (LLMs) are being increasingly adopted for programming work. Prior work shows that while LLMs accelerate task completion for professional programmers, beginnin…
