GalevNB: Galev for N-Body simulations

TL;DR

GalevNB is a software tool that integrates N-body simulation data with stellar population models to produce observable magnitudes and spectra, facilitating direct comparison with astronomical observations.

Contribution

It introduces GalevNB, enabling N-body simulation data to be converted into observational magnitudes and spectra using GALEV models, which was not previously available.

Findings

Enables direct comparison between N-body simulations and observations.

Supports multiple instruments and filters for realistic observational data.

Provides spectra from far-UV to near-IR for simulated stellar populations.

Abstract

We report on GalevNB (Galev for N-Body simulations), an integrated software solution that provides N-body users direct access to the software package GALEV (GALaxy EVolutionary synthesis models). GalevNB is developed for the purpose of a direct comparison between N-body simulations and observations. It converts the fundamental stellar properties of N-body simulations, i.e., stellar mass, temperature, stellar luminosity and metallicity, into observational magnitudes for a variety of filters of widely used instruments/telescopes (HST, ESO, SDSS, 2MASS), and into spectra that span from far-UV (90 $\rm \AA$) to near-IR (160 $\rm \mu$m).
