Searching for codes credited to 'Winter, Walter'

Tip! Refine or expand your search. Authors are sometimes listed as 'Smith, J. K.' instead of 'Smith, John' so it is useful to search for last names only. Note this is currently a simple phrase search.

[ascl:2109.018] GLoBES: General Long Baseline Experiment Simulator

GLoBES simulates long baseline neutrino oscillation experiments. The package features full incorporation of correlations and degeneracies in the oscillation parameter space, advanced routines for the treatment of arbitrary systematical errors, and user-defined priors, which allowsn for the inclusion of arbitrary external physical information. Its use of AEDL, the Abstract Experiment Definition Language, provides an easy way to define experimental setups. GLoBES also provides an interface for the simulation of non-standard physics, and offers predefined setups for many experiments, including Superbeams, Beta Beams, Neutrino factories, Reactors, and various detector technologies.

[ascl:2312.031] AM3: Astrophysical Multi-Messenger Modeling

AM3 simulates lepto-hadronic interactions in astrophysical environments. It solves the time-dependent partial differential equations for the energy spectra of electrons, positrons, protons, neutrons, photons, neutrinos as well as charged secondaries (pions and muons), immersed in an isotropic magnetic field. The code accounts for the emission of photons and charged secondaries in electromagnetic and hadronic interactions feed back into the interaction rates in a time-dependent manner, therefore grasping non-linear effects including electromagnetic cascades. AM3 is computationally efficient, making it possible to scan vast source parameter scans and fit the observational data, and has been deployed to explain multi-wavelength observations from blazars, gamma-ray bursts and tidal disruption events.
