VALES VIII: Weak ionized gas outflows in star-forming galaxies at traced with VLT/MUSE
Guilherme S. Couto, Thomas M. Hughes, Médéric Boquien +4
We characterize the ionized gas outflows in 15 low-redshift star-forming galaxies, a Valparaíso ALMA Line Emission Survey (VALES) subsample, using MUSE integral field spectroscopy…
Fornax 3D project: assessing the diversity of IMF and stellar population maps within the Fornax Cluster
I. Martín-Navarro, F. Pinna, L. Coccato +14
The stellar initial mass function (IMF) is central to our interpretation of astronomical observables and to our understanding of most baryonic processes within galaxies. The univer…
The Fornax 3D project: PNe populations and stellar metallicity in edge-on galaxies
P. M. Galán-de Anta, M. Sarzi, T. W. Spriggs +17
Context. Extragalactic Planetary Nebulae (PNe) are useful distance indicators and are often used to trace the dark-matter content in external galaxies. At the same time, PNe can al…
Simultaneous Deep Measurements of CO isotopologues and Dust Emission in Giant Molecular Clouds in the Andromeda Galaxy
Sébastien Viaene, Jan Forbrich, Charles J. Lada +2
We present simultaneous measurements of emission from dust continuum at 230 GHz and the J=2-1 CO, CO and CO isotopologues at 15 pc resolution from indiv…
The Fornax3D project: Assembly histories of lenticular galaxies from a combined dynamical and population orbital analysis
A. Poci, R. M. McDermid, M. Lyubenova +14
Abridged for arXiv: In this work, we apply a powerful new technique in order to observationally derive accurate assembly histories through a self-consistent combined stellar dynami…
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…
AlFoCS + Fornax3D: resolved star formation in the Fornax cluster with ALMA and MUSE
Nikki Zabel, Timothy A. Davis, Marc Sarzi +18
We combine data from ALMA and MUSE to study the resolved (~300 pc scale) star formation relation (star formation rate vs. molecular gas surface density) in cluster galaxies. Our sa…
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 Fornax 3D project: Non-linear colour-metallicity relation of globular clusters
K. Fahrion, M. Lyubenova, M. Hilker +15
Globular cluster (GC) systems of massive galaxies often show a bimodal colour distribution. This has been interpreted as a metallicity bimodality, created by a two-stage galaxy for…
The Fornax 3D project: Globular clusters tracing kinematics and metallicities
K. Fahrion, M. Lyubenova, M. Hilker +15
Globular clusters (GCs) are found ubiquitously in massive galaxies and due to their old ages, they are regarded as fossil records of galaxy evolution. Spectroscopic studies of GC s…
