Spectral Templates Optimal for Selecting Galaxies at z > 8 with the JWST
The Astrophysical Journal, 2023 The selection of high-redshift galaxies often involves spectral energy distribution (SED) fitting to photometric data, an expectation for contamination levels, and measurement of sample completeness—all vetted through comparison to spectroscopic redshift

The Local Group on FIRE: dwarf galaxy populations across a suite of hydrodynamic simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present a new set of high-resolution hydrodynamic cosmological zoom-in simulations that apply the Feedback In Realistic Environments physics to both Local Group (LG)-like and isolated Milky Way (MW)-like volumes (10 host systems in total with a ...

Photometric Accuracy of Deconvolved Simulated Astronomical Images
The Astrophysical Journal, 2005 A study of the photometric accuracy of deconvolved astronomical images was undertaken by processing two simulated images with several well-known algorithms. The simulations consisted of an image of a simple star field and an image of an active galactic nucleus (AGN).

Dust attenuation, dust emission, and dust temperature in galaxies at z ≥ 5: a view from the FIRE-2 simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present a suite of 34 high-resolution cosmological zoom-in simulations consisting of thousands of haloes up to $M_{\rm halo}\sim 10^{12}\, \mathrm{M}_{\odot }$ ($M_{\ast }\sim 10^{10.5}\, \mathrm{M}_{\odot }$) at z ≥ 5 from the Feedback in Realistic

Deep generative models for galaxy image simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2020 Image simulations are essential tools for preparing and validating the analysis of current and future wide-field optical surveys. However, the galaxy models used as the basis for these simulations are typically limited to simple parametric light ...

A DETERMINATION OF DARK MATTER BISPECTRUM WITH A LARGE SET OF N-BODY SIMULATIONS
, 2009 We use a set of numerical N-body simulations to study the large-scale behavior of the reduced bispectrum of dark matter and compare the results with the second-order perturbation theory and the halo models for different halo mass functions.
