Predicting far-infrared maps of galaxies via machine learning techniques
Wouter Dobbels, Maarten Baes
The ultraviolet (UV) to sub-millimetre (submm) spectral energy distribution of galaxies can be roughly divided into two sections: the stellar emission (attenuated by dust) at UV to…
Probing the spectral shape of dust emission with the DustPedia galaxy sample
Angelos Nersesian, Wouter Dobbels, Manolis E. Xilouris +10
The objective of this paper is to understand the variance of the far-infrared (FIR) spectral energy distribution (SED) of the DustPedia galaxies, and its link with the stellar and…
A Nearby Galaxy Perspective on Dust Evolution. Scaling relations and constraints on the dust build-up in galaxies with the DustPedia and DGS samples
Frédéric Galliano, Angelos Nersesian, Simone Bianchi +14
Methods. We have modelled a sample of ~800 nearby galaxies, spanning a wide range of metallicity, gas fraction, specific star formation rate and Hubble stage. We have derived the d…
High-resolution, 3D radiative transfer modelling V. A detailed model of the M51 interacting pair
Angelos Nersesian, Sebastien Viaene, Ilse De Looze +13
Investigating the dust heating mechanisms in galaxies provides a deeper understanding of how the internal energy balance drives their evolution. Over the last decade, radiative tra…
Nonparametric galaxy morphology from UV to submm wavelengths
Maarten Baes, Angelos Nersesian, Viviana Casasola +13
We present the first nonparametric morphological analysis of a set of spiral galaxies from UV to submm wavelengths. Our study is based on high-quality multi-wavelength imaging for…
High-resolution, 3D radiative transfer modelling IV. AGN-powered dust heating in NGC 1068
S. Viaene, A. Nersesian, J. Fritz +18
Dust emission, an important diagnostic of star formation and ISM mass throughout the Universe, can be powered by sources unrelated to ongoing star formation. In the framework of th…
High-resolution, 3D radiative transfer modelling III. The DustPedia barred galaxies
Angelos Nersesian, Sam Verstocken, Sebastien Viaene +17
Context: Dust in late-type galaxies in the local Universe is responsible for absorbing approximately one third of the energy emitted by stars. It is often assumed that dust heating…
High-resolution, 3D radiative transfer modelling. II. The early-type spiral galaxy M81
Sam Verstocken, Angelos Nersesian, Maarten Baes +14
Interstellar dust absorbs stellar light very efficiently and thus shapes the energetic output of galaxies. Studying the impact of different stellar populations on the dust heating…
Reproducing the Universe: a comparison between the EAGLE simulations and the nearby DustPedia galaxy sample
Ana Trčka, Maarten Baes, Peter Camps +17
We compare the spectral energy distributions (SEDs) and inferred physical properties for simulated and observed galaxies at low redshift. We exploit UV-submillimetre mock fluxes of…
The ISM scaling relations in DustPedia late-type galaxies: A benchmark study for the Local Universe
Viviana Casasola, Simone Bianchi, Pieter De Vis +18
The purpose of this work is the characterization of the main scaling relations between all the ISM components (dust, atomic/molecular/total gas), gas-phase metallicity, and other g…
Predicting the global far-infrared SED of galaxies via machine learning techniques
W. Dobbels, M. Baes, S. Viaene +10
Dust plays an important role in shaping a galaxy's spectral energy distribution (SED). It absorbs ultraviolet (UV) to near-infrared (NIR) radiation and re-emits this energy in the…
Dust emissivity and absorption cross section in DustPedia late-type galaxies
S. Bianchi, V. Casasola, M. Baes +16
Aims: We compare the far-infrared to sub-millimetre dust emission properties measured in high Galactic latitude cirrus with those determined in a sample of 204 late-type DustPedia…
The First Maps of -- the Dust Mass Absorption Coefficient -- in Nearby Galaxies, with DustPedia
Christopher J. R. Clark, Pieter De Vis, Maarten Baes +17
The dust mass absorption coefficient, , is the conversion function used to infer physical dust masses from observations of dust emission. However, it is notoriously poorly c…
Old and young stellar populations in DustPedia galaxies and their role in dust heating
A. Nersesian, E. M. Xilouris, S. Bianchi +19
Within the framework of the DustPedia project we investigate the properties of cosmic dust and its interaction with the stellar radiation (originating from different stellar popula…
Morphology-assisted galaxy mass-to-light predictions using deep learning
Wouter Dobbels, Serge Krier, Stephan Pirson +4
One of the most important properties of a galaxy is the total stellar mass, or equivalently the stellar mass-to-light ratio (M/L). It is not directly observable, but can be estimat…
The cosmic spectral energy distribution in the EAGLE simulation
Maarten Baes, Ana Trčka, Peter Camps +4
The cosmic spectral energy distribution (CSED) is the total emissivity as a function of wavelength of galaxies in a given cosmic volume. We compare the observed CSED from the UV to…
The fraction of bolometric luminosity absorbed by dust in DustPedia galaxies
S. Bianchi, P. De Vis, S. Viaene +16
We study the fraction of stellar radiation absorbed by dust, f_abs, in 814 galaxies of different morphological types. The targets constitute the vast majority (93%) of the DustPedi…
