Jon Davies

Jon Davies

DustPedia PI

Jon is PI of DustPedia and works at the University of Cardiff. His main research interests are the chemical evolution of galaxies and the influence cosmic dust has on our observations of both galaxies and the Universe. He is also interested in dwarf galaxy populations and their role in galaxy formation. He is also working on an archaeological project to use satellite imaging to discover ancient sites.

Manolis Xilouris

Manolis Xilouris

co-PI

Manolis is a CoI of DustPedia working at the national Observatory in Athens. His interests lie in observational Extragalactic Astrophysics, with emphasis in Space Infrared Astronomy. He has been working mostly on problems related to Transfer of Radiation within galaxies, studies of the properties of dust in nearby galaxies as well as the studies of the interstellar medium in (Ultra) Luminous Infrared Galaxies (ULIRGs).

Within the DustPedia project he is applying applications of SED models to early-type galaxies, exploring relations and correlations of the derived parameters of the DustPedia sample, constructing and maintaining the DustPedia database. He is responsible for the dissemination of the DustPedia results through publications and scientific meetings.

Ant Jones

Ant Jones

co-PI

Ant is a CoI of DustPedia working at the University of Paris South. He works on the physics of amorphous interstellar carbonaceous and silicate dust in all its guises and, especially, the evolution of the dust properties (a.k.a. the optical properties as a function of composition, structure, size, ...) in response to the local conditions and the systematic variation of those properties from one region to another.

Within DustPedia he is developing and extending the existing THEMIS dust modelling approach (The Heterogeneous dust Evolution Model at the IaS) in the interpretation of the observed dust emission in galactic interstellar media (diffuse, clouds, photon-dominated regions, ionised/HII regions, ...).

Maarten Baes

Maarten Baes

co-PI

Maarten Baes of the University of Ghent is interested in various aspects of interstellar dust in galaxies, Monte Carlo radiative transfer and galaxy evolution. In the DustPedia project, he and his team are responsible for the PACS data reduction, the coordination of the project, and the radiative transfer modelling of the most nearby galaxies.

Simone Bianchi

Simone Bianchi

co-PI

Simone is a research astronomer at Arcetri. He is interested in understanding the role of the dust and stellar distributions in shaping the radiative transfer and energy balance of radiation in spiral galaxies. He is currently studying the properties of the dust, gas and stellar distributions in a sample of 18 large face-on galaxies and checking the data-reduction pipeline and astrometry of the DustPedia sample.

Suzanne Madden

Suzanne Madden

co-PI

Suzanne is a research astronomer at CEA, Paris. She has a particular interest in star forming dwarf galaxies. She is currently developing and using a model to fit the spectral energy distributions of DustPedia galaxies.

Sam  Verstocken

Sam Verstocken

Sam is a PhD student at the University of Ghent. His main research interest is in the intersection of computing (parallelisation, automatisation, AI) and astrophysics, more specifically 3D dust radiative transfer. He is using radiative transfer models to provide a detailed analysis of heating of dust in large DustPedia galaxies.

Chris Clark

Chris Clark

Chris is a post doc working at Cardiff University, he is particularly interested in the interstellar dust found in relatively immature galaxies; systems that are more evolved than very low metallicity dwarf galaxies, but which have a long way to go before they're as evolved as the Milky Way. Such galaxies appear to have built up large dust masses very quickly, and their dust seems to have unusual properties. He also studies evolved stars in our own Galaxy, to understand their contributions to the Galactic dust budget.

As part of DustPedia, Chris is responsible for providing the bulk of the observational data. He is producing homogeneous reductions of Herschel-SPIRE data and acquiring and standardise multi-wavelength ancillary data. He is using this collected dataset to provide consistent photometry for all of the galaxies in our sample.

Marco Bocchio

Marco Bocchio

Marco is a post doc at University of Paris South. His research focuses on dust modelling in extreme environments such as supernovae and hot gas both in Galactic and extragalactic sources. He is developing a model to measure the fraction of dust in different environments as a function of galactic type, with particular attention to the theoretical modelling of dust charge in HII regions.

Sophia Lianou

Sophia Lianou

Sophia is a post doc at CEA, Paris. Her research interests focus on understanding the detailed physical properties of the interstellar medium versus the star formation activity for a wide range of galaxy types and galactic environments. Within the DustPedia, project she will model the spectral energy distributions of a large sample of local galaxies, in order to understand their dust and gas properties on local and global scales; their spectral energy distributions will be modelled using the Hierarchical Bayesian model developed at CEA by F. Galliano.

Frederic Galliano

Frederic Galliano

Frederic works at CEA, Paris, on the modelling of the dust and gas properties in the nearby universe, with a particular, but non-exclusive, interest for low-metallicity environments. He has developed a hierarchical Bayesian SED modelling code, aimed at deriving dust properties and physical conditions from the data, with the highest accuracy possible. He is assisting other DustPedia team members in applying this model to the DustPedia sample.

Viviana Casasola

Viviana Casasola

Viviana is a post doc at Arcetri. Her research interests are the gas and dust content of galaxies and processes of star formation studied through observations at different wavelengths. Her role in the DustPedia project is the comparative study of dust, stars and gas profiles and properties/correlations in DustPedia galaxies.

Sebastien Viaene

Sebastien Viaene

Sebastien Viaene is a PhD student at Gehnt. He has been investigating the interplay of starlight and dust in Andromeda and other nearby galaxies through various methods. Within DustPedia he has been involved with the PACS data reduction and radiative transfer modelling of resolved galaxies.

Jacopo Fritz

Jacopo Fritz

Jacopo Fritz’s main research interests are the properties of stellar populations in local cluster galaxies and the evolutionary link to their higher redshift counterparts, the modelling of the infrared emission of AGN and application to the study of the observed SED, and properties of dust in nearby galaxies. Within DustPedia he is responsible for PACS data reduction and is interested in the study of the influence of AGN on the dust heating at large scales.

Letizia Cassara

Letizia Cassara

Letizia Cassara is a post doctoral worker at the national observatory in Athens. Her main interests are the study of the formation and evolution of both nearby and high-z galaxies, mainly by means of evolutionary population synthesis models. Within DustPedia she is studying the physical properties of Early Type Galaxies taking advantage of the SED fitting between observations and theoretical models, and considering the presence of the interstellar dust.

Ilse de Looze

Ilse de Looze

Ilse’s main research area is the study of dust and gas in nearby galaxies. On the one hand, she works on dust and molecules in supernova remnants to constrain the dust production rate of core-collapse supernova. On the other, she studies the variation in dust properties in nearby galaxies through 3D panchromatic radiative transfer models. She is assisting in radiative transfer modelling and the model interpretation for the resolved nearby galaxies.

Gururaj Wagle

Gururaj Wagle

Gururaj is a post doc at University of Paris South. His research focuses on the dust in the photo-dissociation regions (PDR) in the galactic and extra-galactic media. Currently, he is developing a model for the Horsehead PDR using the appropriate radiation field and exploring dust evolution within the framework of the THEMIS dust model.
