Quantum-Corrected Cosmological Perturbation Solver Live TRY https://qcuas-quantum-cosmology-astrophysics-unified-suite.streamlit.app/ or Beta https://qcaustfordmodel.streamlit.app/ License: Dual 🔬 Overview A complete computational framework for cosmological perturbation theory with first-principles quantum corrections. This package implements: Quantum-corrected Mukhanov-Sasaki equations with backreaction from quantum fields Full Boltzmann integration with quantum...

As of August 2018 Spheral++ has moved to Github -- please see the current repository at https://github.com/jmikeowen/spheral We are leaving a frozen version here on SourceForge for historical reasons. Spheral++ provides a steerable parallel environment for performing coupled hydrodynamical & gravitational numerical simulations. Hydrodynamics and gravity are modelled using particle based methods (SPH and N-Body).

The GPU-BH tree solver is a FLASH4 module to calculate the gravitational potential using a CUDA device.

This program is centered on a graphical Hertzsprung-Russell or color-magnitude diagram (CMD). It can show animated evolutionary tracks of stars of different masses, for a single star or a population of stars. In addition, it can show the CMD of a large number of existing open clusters, based on scientific survey data, and overlay isochrones (the curve in a CMD from stars born at the same time) to determine the age, distance and interstellar reddening of the cluster. Determining these...

...This application is designed to sort FITS star image files taken by professional astronomers at observatories. The application sorts the files by their image type: Bias, Dark, Flat, and Object. The Flat and Object images are sorted by filters U, B, V, R, and I. The application allows the user to create and save a profile of a given observatory's FITS header format, for future sorting use. This application also provides a header viewer for FITS image file.
