Serendipitous discovery of an optical emission line jet in NGC\,232
C. Lopez-Coba, S. F. Sanchez, I. Cruz-Gonzalez +9
We report the detection of a highly collimated linear emission-line structure in the spiral galaxy NGC\,232 through the use of integral field spectroscopy data from the All-weather…
The Gaia -ESO Survey: Lithium enrichment histories of the Galactic thick and thin disc
Xiaoting. Fu, D. Romano, A. Bragaglia +32
Lithium abundance in most of the warm metal-poor main sequence stars shows a constant plateau (A(Li)~2.2 dex) and then the upper envelope of the lithium vs. metallicity distributio…
The AMIGA sample of isolated galaxies XIII. The HI content of an almost "nurture free" sample
Michael G. Jones, Daniel Espada, Lourdes Verdes-Montenegro +8
We present the largest catalogue of HI single dish observations of isolated galaxies to date and the corresponding HI scaling relations, as part of the multi-wavelength project AMI…
Morpho-kinematic properties of field S0 bulges in the CALIFA survey
J. Mendez-Abreu, J. A. L. Aguerri, J. Falcon-Barroso +22
We study a sample of 28 S0 galaxies extracted from the integral-field spectroscopic (IFS) survey CALIFA. We combine an accurate two-dimensional (2D) multi-component photometric dec…
Radio synchrotron spectra of star-forming galaxies
Uli Klein, Ute Lisenfeld, Simon Verley
The radio continuum spectra of 14 star-forming galaxies are investigated by fitting nonthermal (synchrotron) and thermal (free-free) radiation laws. The underlying radio continuum…
The shape of oxygen abundance profiles explored with MUSE: evidence for widespread deviations from single gradients
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +6
We characterise the oxygen abundance radial distribution of a sample of 102 spiral galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial resolution of the dat…
The Role of Stellar Radial Motions in Shaping Galaxy Surface Brightness Profiles
T. Ruiz-Lara, C. G. Few, E. Florido +3
Aims: The physics driving features such as breaks observed in galaxy surface brightness (SB) profiles remains contentious. Here, we assess the importance of stellar radial motions…
Star formation in the local Universe from the CALIFA sample. II. Activation and quenching mechanisms in bulges, bars, and disks
C. Catalán-Torrecilla, A. Gil de Paz, A. Castillo-Morales +22
We estimate the current extinction-corrected H star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multi-…
The role of molecular gas in galaxy transition in compact groups
U. Lisenfeld, K. Alatalo, C. Zucker +4
Compact groups (CGs) provide an environment in which interactions between galaxies and with the intra-group medium enable and accelerate galaxy transitions from actively star formi…
The complexity of Orion: an ALMA view. II. gGg'-Ethylene Glycol and Acetic Acid
Cécile Favre, Laurent Pagani, Paul Goldsmith +5
We report the first detection and high angular resolution (1.8" 1.1") imaging of acetic acid (CHCOOH) and gGg--ethylene glycol (gGg(CHOH)…
Observational constraints to boxy/peanut bulge formation time
I. Perez, I. Martinez-Valpuesta, T. Ruiz-Lara +10
Boxy/peanut bulges are considered to be part of the same stellar structure as bars and both could be linked through the buckling instability. The Milky Way is our closest example.…
Arm and interarm abundance gradients in CALIFA spiral galaxies
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +23
Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with easily distinguishable c…
Observational hints for radial migration in disc galaxies from CALIFA
T. Ruiz-Lara, I. Pérez, E. Florido +22
Context: According to numerical simulations, stars are not always kept at their birth galactocentric distances but migrate. The importance of this radial migration in shaping galac…
The Wolf-Rayet star population in the dwarf galaxy NGC 625
Ana Monreal-Ibero, Jeremy R. Walsh, Jorge Iglesias-Paramo +4
ABRIGED: Quantifying the number, type and distribution of W-R stars is a key component in the context of galaxy evolution, since they put constraints on the age of the star formati…
The Mass-Metallicity Relation revisited with CALIFA
S. F. Sánchez, J. K. Barrera-Ballesteros, L. Sánchez-Menguiano +14
We present an updated version of the mass--metallicity relation (MZR) using integral field spectroscopy data obtained from 734 galaxies observed by the CALIFA survey. These unparal…
Probing the Broad Line Region and the Accretion Disk in the Lensed Quasars HE0435-1223, WFI2033-4723, and HE2149-2745 using Gravitational Microlensing
V. Motta, E. Mediavilla, K. Rojas +3
We use single-epoch spectroscopy of three gravitationally lensed quasars, HE0435-1223, WFI2033-4723, and HE2149-2745, to study their inner structure (BLR and continuum source). We…
Limits on the Mass and Abundance of Primordial Black Holes from Quasar Gravitational Microlensing
E. Mediavilla, J. JimÉnez-Vicente, J. A. MuÑoz +2
The idea that dark matter can be made of intermediate-mass primordial black holes in the range has recently been reconsidered, particular…
Powerful H2 Line Cooling in Stephan's Quintet II. Group-wide Gas and Shock Modeling of the Warm H2 and a Comparison with [CII]157.7um Emission and Kinematics
P. N. Appleton, P. Guillard, A. Togi +7
We map for the first time the two-dimensional H_2 excitation of warm intergalactic gas in Stephan's Quintet on group-wide (50 x 35 kpc^2) scales to quantify the temperature, mass a…
