Deep learning for galaxy surface brightness profile fitting
D. Tuccillo, M. Huertas-Company, E. Decencière +3
Numerous ongoing and future large area surveys (e.g. DES, EUCLID, LSST, WFIRST), will increase by several orders of magnitude the volume of data that can be exploited for galaxy mo…
Revisiting Stephan's Quintet with deep optical images

We present far-infrared observations of Monoceros R2 (a giant molecular cloud at approximately 830 pc distance, containing several sites of active star formation), as observed at 7…
LOFAR-Boötes: Properties of high- and low-excitation radio galaxies at
W. L. Williams, G. Calistro Rivera, P. N. Best +13
This paper presents a study of the redshift evolution of radio-loud active galactic nuclei (AGN) as a function of the properties of their galaxy hosts in the Boötes field. To achie…
Pair-matching of radio-loud and radio-quiet AGNs
D. Kozieł-Wierzbowska, G. Stasińska, N. Vale Asari +3
Active galactic nuclei (AGNs) are known to cover an extremely broad range of radio luminosities and the spread of their radio-loudness is very large at any value of the Eddington r…
Improving galaxy morphologies for SDSS with Deep Learning
H. Domínguez Sánchez, M. Huertas-Company, M. Bernardi +2
We present a morphological catalogue for 670,000 galaxies in the Sloan Digital Sky Survey in two flavours: T-Type, related to the Hubble sequence, and Galaxy Zoo 2 (GZ2 here…
Dust temperature and mid-to-total infrared color distributions for star-forming galaxies at 0<z<4
Corentin Schreiber, David Elbaz, Maurilio Pannella +3
We present a new, publicly available library of dust spectral energy distributions (SEDs). These SEDs are characterized by only three parameters: the dust mass (Mdust), the dust te…
AGN feedback in dwarf galaxies?
Gohar Dashyan, Joseph Silk, Gary A. Mamon +2
Dwarf galaxy anomalies, such as their abundance and cusp-core problems, remain a prime challenge in our understanding of galaxy formation. The inclusion of baryonic physics could p…
Tracing the evolution of dust obscured star-formation and accretion back to the reionisation epoch with SPICA
C. Gruppioni, L. Ciesla, E. Hatziminaoglou +35
Our current knowledge of star formation and accretion luminosity at high-redshift (z>3-4), as well as the possible connections between them, relies mostly on observations in the re…
Galaxy evolution studies with the SPace IR telescope for Cosmology and Astrophysics (SPICA): the power of IR spectroscopy
L. Spinoglio, A. Alonso-Herrero, L. Armus +65
IR spectroscopy in the range 12-230 micron with the SPace IR telescope for Cosmology and Astrophysics (SPICA) will reveal the physical processes that govern the formation and evolu…
SPICA and the Chemical Evolution of Galaxies: The Rise of Metals and Dust
J. A. Fernández-Ontiveros, L. Armus, M. Baes +33
The physical processes driving the chemical evolution of galaxies in the last cannot be understood without directly probing the dust-obscured phase of star-for…
What is the Milky Way outer halo made of? High resolution spectroscopy of distant red giants
G. Battaglia, P. North, P. Jablonka +5
In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to consist mainly of the shr…
The natural emergence of the correlation between H2 and star formation rate surface densities in galaxy simulations
Alessandro Lupi, Stefano Bovino, Pedro R. Capelo +2
In this study, we present a suite of high-resolution numerical simulations of an isolated galaxy to test a sub-grid framework to consistently follow the formation and dissociation…
