Diffuse ionized gas in galaxies across the Hubble sequence at the CALIFA resolution
E. A. D. Lacerda, R. Cid Fernandes, G. S. Couto +7
We use spatially resolved spectroscopy from the Calar Alto Legacy Field Area (CALIFA) survey to study the nature of the line emitting gas in galaxies of different Hubble types, foc…
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
Pierre-Alain Duc, Jean-Charles Cuillandre, Florent Renaud
Stephan's Quintet, a compact group of galaxies, is often used as a laboratory to study a number of phenomena, including physical processes in the interstellar medium, star formatio…
The relativistic jet of the gamma-ray emitting narrow-line Seyfert 1 galaxy 1H 0323+342
Daniel Kynoch, Hermine Landt, Martin J. Ward +7
The detection of several radio-loud narrow-line Seyfert 1 (NLS1) galaxies by the Fermi Gamma-Ray Space Telescope hints at the existence of a rare, new class of gamma-ray emitting a…
Far-infrared observations of a massive cluster forming in the Monoceros R2 filament hub
T. S. M. Rayner, M. J. Griffin, N. Schneider +29
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…
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…
SHARDS Frontier Fields: Physical properties of a low mass Lyman-alpha emitter at z=5.75
Antonio Hernán-Caballero, Pablo G. Pérez-González, José M. Diego +20
We analyze the properties of a multiply-imaged Lyman-alpha (Lya) emitter at z=5.75 identified through SHARDS Frontier Fields intermediate-band imaging of the Hubble Frontier Fields…
Stellar mass functions and implications for a variable IMF
M. Bernardi, R. K. Sheth, J. -L. Fischer +6
Spatially resolved kinematics of nearby galaxies has shown that the ratio of dynamical- to stellar population-based estimates of the mass of a galaxy () correlat…
The diversity of assembly histories leading to disc galaxy formation in a LambdaCDM model
Andreea S. Font, Ian G. McCarthy, Amandine M. C. Le Brun +2
[Abridged] Typical disc galaxies forming in a LambdaCDM cosmology encounter a violent environment, where they often experience mergers with massive satellites. The fact that disc g…
What distinguishes the host galaxies of radio-loud and radio-quiet AGNs?
D. Kozieł-Wierzbowska, N. Vale Asari, G. Stasińska +3
We compare the optical properties of the host galaxies of radio-quiet (RQ) and radio-loud (RL) Type 2 active galactic nuclei (AGNs) to infer whether the jet production efficiency d…
Mass and metallicity scaling relations of high redshift star-forming galaxies selected by GRBs
M. Arabsalmani, P. Møller, D. A. Perley +19
We present a comprehensive study of the relations between gas kinematics, metallicity, and stellar mass in a sample of 82 GRB-selected galaxies using absorption and emission method…
The XXL Survey XIX. A realistic population of simulated X-ray AGN: Comparison of models with observations
E. Koulouridis, L. Faccioli, A. M. C. Le Brun +11
Modern cosmological simulations rely heavily on feedback from active galactic nuclei (AGN) in order to stave off overcooling in massive galaxies and galaxy groups and clusters. An…
Mapping diffuse interstellar bands in the local ISM on small scales via MUSE 3D spectroscopy
Martin Wendt, Tim-Oliver Husser, Sebastian Kamann +6
We map the interstellar medium (ISM) including the diffuse interstellar bands (DIBs) in absorption toward the globular cluster NGC 6397 using VLT/MUSE. This pilot study demonstrate…
Determining the Halo Mass Scale where Galaxies Lose Their Gas
Gregory Rudnick, Pascale Jablonka, John Moustakas +9
A major question in galaxy formation is how the gas supply that fuels activity in galaxies is modulated by their environment. We use spectroscopy of a set of well characterized clu…
Detailed chemical composition of classical Cepheids in the LMC cluster NGC 1866 and in the field of the SMC
B. Lemasle, M. A. T. Groenewegen, E. K. Grebel +11
Context: Cepheids are excellent tracers of young stellar populations. They play a crucial role in astrophysics as standard candles. The chemistry of classical Cepheids in the Milky…
Morphology and enhanced star formation in a Cartwheel-like ring galaxy
