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…
The Nuker model for galactic nuclei
Maarten Baes
The Nuker profile, characterised by an inner and outer power-law profile smoothly merged around a break radius, is a very popular model to describe the surface brightness profile o…
Evidence of dust grain evolution from extinction mapping in the IC 63 photodissociation region
Dries Van De Putte, Karl D. Gordon, Julia Roman-Duval +5
Photodissociation regions (PDRs) are parts of the ISM consisting of predominantly neutral gas, located at the interface between H II regions and molecular clouds. The physical cond…
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…
Panchromatic SED fitting codes and modelling techniques
Maarten Baes
Modelling and interpreting the SEDs of galaxies has become one of the key tools at the disposal of extragalactic astronomers. Ideally, we could hope that, through a detailed study…
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…
Stellar systems following the luminosity law. IV. The total energy and the central concentration of galaxies
Maarten Baes, Luca Ciotti
We expand our previous analytical and numerical studies of the family of Sérsic models, routinely used to describe early-type galaxies and the bulges of spiral galaxies. In particu…
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…
Optical depth in polarised Monte Carlo radiative transfer
Maarten Baes, Christian Peest, Peter Camps +1
Context: The Monte Carlo method is the most widely used method to solve radiative transfer problems in astronomy, especially in a fully general 3D geometry. A crucial concept in an…
High-Resolution Radiative Transfer Modelling of M33
Thomas G. Williams, Maarten Baes, Ilse De Looze +4
In this work, we characterise the contributions from both ongoing star formation and the ambient radiation field in Local Group galaxy M33, as well as estimate the scale of the loc…
An evolving and mass dependent - relation for galaxies
Antonios Katsianis, Xianzhong Zheng, Valentino Gonzalez +10
The scatter () of the specific star formation rates (sSFRs) of galaxies is a measure of the diversity in their star formation histories (SFHs) at a given mass…
A low-frequency study of recently identified double-double radio galaxies
S. Nandi, D. J. Saikia, R. Roy +6
In order to understand the possible mechanisms of recurrent jet activity in radio galaxies and quasars, which are still unclear, we have identified such sources with a large range…
DustPedia - the relationships between stars, gas and dust for galaxies residing in different environments
J. I. Davies, A. Nersesian, M. Baes +20
We use a sub-set of the DustPedia galaxy sample (461 galaxies) to investigate the effect the environment has had on galaxies. We consider Virgo cluster and field samples and also a…
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…
DustKING - the story continues: dust attenuation in NGC628
Marjorie Decleir, Ilse De Looze, Médéric Boquien +1
Dust attenuation is a crucial but highly uncertain parameter that hampers the determination of intrinsic galaxy properties, such as stellar masses, star formation rates and star fo…
Revealing the dust attenuation properties on resolved scales in NGC628 with SWIFT UVOT data
Marjorie Decleir, Ilse De Looze, Médéric Boquien +8
Understanding how dust attenuation laws vary between and within galaxies is a key question if we want to reliably measure the physical properties of galaxies at both global and loc…
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 nature of sub-millimeter and highly star-forming galaxies in the EAGLE simulation
Stuart McAlpine, Ian Smail, Richard G. Bower +7
We exploit EAGLE, a cosmological hydrodynamical simulation, to reproduce the selection of the observed sub-millimeter (submm) galaxy population by selecting the model galaxies at $…
A systematic metallicity study of DustPedia galaxies reveals evolution in the dust-to-metal ratios
P. De Vis, A. Jones, S. Viaene +17
Observations of evolution in the dust-to-metal ratio allow us to constrain the dominant dust processing mechanisms. In this work, we present a study of the dust-to-metal and dust-t…
