# Simulations and Software Development Our group has developed several open-source software tools to aid simulation, reconstruction, and analysis for neutrino experimentalists and phenomenologists alike. The software packages that we actively maintain include: ### Prometheus A tool for simulating light yield of charged particles in a water Cherenkov neutrino telescope. Prometheus handles the photon propagation through ice or water and records the resulting photon hits on optical modules. [Github](https://github.com/Harvard-Neutrino/prometheus/tree/main) [arXiv](https://arxiv.org/abs/2304.14526) ### SIREN A tool for simulating rare events, including neutrino interactions or new interactions/decays in BSM models) with realistic detector geometries. SIREN outputs the positions, kinematics, and event weights of visible final state particles [Github](https://github.com/Harvard-Neutrino/SIREN) [arXiv](https://arxiv.org/abs/2406.01745) ### NuSQuIDS A tool for propagating neutrinos through a given density profile, incorporating oscillations as well as matter effects from coherent and non-coherent neutrino interactions. [Github](https://github.com/arguelles/nuSQuIDS) [arXiv](https://arxiv.org/abs/2112.13804) ### GollumFit A tool for performing binned-likelihood analyses on neutrino telescope data, from IceCube or otherwise. GollumFit has the ability to fit over several nuisance parameters at once. [Github](https://github.com/icecube/GollumFit) [arXiv](https://arxiv.org/abs/2506.04491) ### TAMBO-MC Public monte carlo simulation framework for the Tau Mountain-Based Observatory. TAMBO-MC is written in julia interfaces with the latest version of CORSIKA to simulate air showers from tau decays in the valley. [Github](https://github.com/Harvard-Neutrino/TAMBO-MC) [arXiv](https://arxiv.org/abs/2507.08524) ### Neptune An efficient point-cloud transformer for reconstruction and classification tasks on neutrino telescope data [Github](https://github.com/felixyu7/neptune/) [arXiv](https://arxiv.org/abs/2510.01733)
