Lossless Compression Performance for PETRA III Datasets
Malte Buschmann, Yannis Schumann, Christian Voss +2
Large-scale research facilities increasingly face the challenge of managing rapidly growing data volumes while maintaining sustainable archival infrastructures. We present the firs…
Axion mass prediction from adaptive mesh refinement cosmological lattice simulations
Joshua N. Benabou, Malte Buschmann, Joshua W. Foster +1
The quantum chromodynamics (QCD) axion arises as the pseudo-Goldstone mode of a spontaneously broken abelian Peccei-Quinn (PQ) symmetry. If the scale of PQ symmetry breaking occurs…
Sledgehamr: Simulating Scalar Fields with Adaptive Mesh Refinement
Malte Buschmann
Understanding the nonlinear dynamics of coupled scalar fields often necessitates simulations on a 3D mesh. These simulations can be computationally expensive if a large scale separ…
The Cosmological Dynamics of String Theory Axion Strings
Joshua N. Benabou, Quentin Bonnefoy, Malte Buschmann +2
The quantum chromodynamics (QCD) axion may solve the strong CP problem and explain the dark matter (DM) abundance of our Universe. The axion was originally proposed to arise as the…
Signatures of Primordial Energy Injection from Axion Strings
Joshua N. Benabou, Malte Buschmann, Soubhik Kumar +2
Axion strings are horizon-size topological defects that may be produced in the early Universe. Ultra-light axion-like particles may form strings that persist to temperatures below…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
