Visualizing many-particle astronomical simulations

ACM SIGGRAPH 2007 posters, 2007
Astronomers often work on many-particle systems. For example, the Earth had been formed from millions of planetesimals, and a galaxy contains hundreds of billions of stars. We have developed a GUI visualization tool specialized for astronomical many-particle simulations.

MAISIE: a multipurpose astronomical instrument simulator environment

SPIE Proceedings, 2016
Astronomical instruments often need simulators to preview their data products and test their data reduction pipelines. Instrument simulators have tended to be purpose-built with a single instrument in mind, and at- tempting to reuse one of these simulators for a different purpose is often a slow and difficult task.

Optimizing Numerical Simulations of Colliding Galaxies. II. Comparing Simulations to Astronomical Observations

Research Notes of the AAS, 2020
Abstract Our research focuses on determining the dynamical orbital parameters associated with galaxy collisions. We are accomplishing this by optimizing numerical models of galactic interactions with astronomical observations of colliding galaxies and measuring the uncertainty in the parameter space of these models. This paper will focus

Numerical simulation of astronomical observations with ISO-LWS

Il Nuovo Cimento C, 1993
The purpose of this work is the numerical simulation of the ISO-LWS spectrometer output with a computer code aiming at obtaining data similar as far as possible to those to be gained during the mission. With such data the processing and analysis programmes will be tested in order to assess the instrument capabilities and limits.
