Decoding NGC 628 with radiative transfer methods
M. T. Rushton, C. C. Popescu, C. Inman +2
We present an axi-symmetric model for the ultraviolet (UV)-to-submillimetre (submm) images of the nearly face-on spiral galaxy NGC 628. It was calculated using a radiative transfer…
A radiation transfer model for the Milky Way. II The global properties and large scale structure
Giovanni Natale, Cristina C. Popescu, Mark Rushton +3
We obtained an axi-symmetric model for the large-scale distribution of stars and dust in the Milky Way (MW) using a radiative transfer code that can account for the existing near-i…
A radiative transfer model for the spiral galaxy M33
Jordan J. Thirlwall, Cristina C. Popescu, Richard J. Tuffs +5
We present the first radiative transfer (RT) model of a non-edge-on disk galaxy in which the large-scale geometry of stars and dust is self-consistently derived through fitting of…
Ray-tracing 3D dust radiative transfer with DART-Ray: code upgrade and public release
Giovanni Natale, Cristina C. Popescu, Richard. J. Tuffs +6
We present an extensively updated version of the purely ray-tracing 3D dust radiation transfer code DART-Ray. The new version includes five major upgrades : 1) a series of optimiza…
A radiation transfer model for the Milky-Way: I. Radiation fields and application to High Energy Astrophysics
C. C. Popescu, R. Yang, R. J. Tuffs +3
We present a solution for the ultraviolet (UV) - submillimeter (submm) interstellar radiation fields (ISRFs) of the Milky Way, derived from modelling COBE, IRAS and Planck maps of…
TRUST I: A 3D externally illuminated slab benchmark for dust radiative transfer
K. D. Gordon, M. Baes, S. Bianchi +8
The radiative transport of photons through arbitrary three-dimensional (3D) structures of dust is a challenging problem due to the anisotropic scattering of dust grains and strong…
Dust radiative transfer modelling of the infrared ring around the magnetar SGR 190014
G. Natale, N. Rea, D. Lazzati +3
A peculiar infrared ring-like structure was discovered by {\em Spitzer} around the strongly magnetised neutron star SGR 190014. This infrared structure was suggested to be due t…
Spiral arm kinematics for Milky Way stellar populations
S. Pasetto, G. Natale, D. Kawata +3
We present a new theoretical population synthesis model (the Galaxy Model) to examine and deal with large amounts of data from surveys of the Milky Way and to decipher the present…
Benchmarking the Calculation of Stochastic Heating and Emissivity of Dust Grains in the Context of Radiative Transfer Simulations
Peter Camps, Karl Misselt, Simone Bianchi +9
We define an appropriate problem for benchmarking dust emissivity calculations in the context of radiative transfer (RT) simulations, specifically including the emission from stoch…
Predicting the stellar and non-equilibrium dust emission spectra of high-resolution simulated galaxies with DART-Ray
Giovanni Natale, Cristina C. Popescu, Richard. J. Tuffs +3
We describe the calculation of the stochastically heated dust emission using the 3D ray-tracing dust radiative transfer code DART-Ray, which is designed to solve the dust radiative…
Estimating Galactic gas content using different tracers: Compatibility of results, dark gas, and unidentified TeV sources
Giovanna Pedaletti, Emma de Oña Wilhelmi, Diego F. Torres +1
A large fraction of Galactic very-high energy (VHE; E100 GeV) -ray sources is cataloged as unidentified. In this work we explore the possibility that these unidentified…
A multiwavelength analysis of the clumpy FIR-bright sources in M33
G. Natale, K. Foyle, C. D. Wilson +1
We present a multiwavelength study of a sample of far-infrared (FIR) sources detected on the Herschel broad--band maps of the nearby galaxy M33. We perform source photometry on the…

We present DART-Ray, a new ray-tracing 3D dust radiative transfer (RT) code designed specifically to calculate radiation field energy density (RFED) distributions within dusty gala…
Star Formation & Dust Heating in the FIR Bright Sources of M83
K. Foyle, G. Natale, C. D. Wilson +16
We investigate star formation and dust heating in the compact FIR bright sources detected in the Herschel maps of M83. We use the source extraction code GETSOURCES to detect and ex…
The star formation efficiency in Stephan's Quintet intragroup regions
G. Natale, R. J. Tuffs, C. K. Xu +11
We investigated the star formation efficiency for all the dust emitting sources in Stephan's Quintet (SQ). We inferred star formation rates using Spitzer MIR/FIR and GALEX FUV data…
