Chemical abundances of 1111 FGK stars from the HARPS-GTO planet search sample. III. Sulfur
Ana Rita Costa Silva, Elisa Delgado Mena, Maria Tsantaki
Context. Elemental abundances are of prime importance to help us reconstruct the origin and evolution of stars and galaxies in our Universe. Sulfur abundances have not been as heav…
LLAMA: The - Relation of the most luminous local AGNs
Turgay Caglar, Leonard Burtscher, Bernhard Brand +17
The - relation is considered a result of co-evolution between the host galaxies and their super-massive black holes. For elliptical-bulge hosting inactive gala…
Ten AI Stepping Stones for Cybersecurity
Ricardo Morla
With the turmoil in cybersecurity and the mind-blowing advances in AI, it is only natural that cybersecurity practitioners consider further employing learning techniques to help se…
Stellar populations and physical properties of starbursts in the Antennae galaxy from self-consistent modelling of MUSE spectra
M. L. P. Gunawardhana, J. Brinchmann, P. M. Weilbacher +6
We have modelled the stellar and nebular continua and emission-line intensity ratios of massive stellar populations in the Antennae galaxy using high resolution and self-consistent…
Ionized gas kinematics of massive elliptical galaxies in CALIFA and in cosmological zoom-in simulations
Jan Florian, Bodo Ziegler, Michaela Hirschmann +5
(Abridged) We present an investigation of kinematical imprints of AGN feedback on the Warm Ionized gas Medium (WIM) of massive early-type galaxies (ETGs). To this end, we take a tw…
The peculiar kinematics of the multiple populations in the globular cluster Messier 80 (NGC 6093)
Sebastian Kamann, Emanuele Dalessandro, Nate Bastian +10
We combine MUSE spectroscopy and Hubble Space Telescope ultraviolet (UV) photometry to perform a study of the chemistry and dynamics of the Galactic globular cluster Messier 80 (M8…
The Aarhus Red Giants Challenge I: Stellar structures in the red giant branch phase
V. Silva Aguirre, J. Christensen-Dalsgaard, S. Cassisi +23
(Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the mi…
The Hi-GAL catalogue of dusty filamentary structures in the Galactic Plane
E. Schisano, S. Molinari, D. Elia +27
The recent data collected by {\it Herschel} have confirmed that interstellar structures with filamentary shape are ubiquitously present in the Milky Way. Filaments are thought to b…
XO-7 b: A transiting hot Jupiter with a massive companion on a wide orbit
Nicolas Crouzet, Brian F. Healy, Guillaume Hébrard +16
Transiting planets orbiting bright stars are the most favorable targets for follow-up and characterization. We report the discovery of the transiting hot Jupiter XO-7 b and of a se…
The binary content of multiple populations in NGC 3201
Sebastian Kamann, Benjamin Giesers, Nate Bastian +7
We investigate the binary content of the two stellar populations that coexist in the globular cluster NGC 3201. Previous studies of binary stars in globular clusters have reported…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
Gravitomagnetism in the Lewis cylindrical metrics
L. Filipe O. Costa, José Natário, N. O. Santos
The Lewis solutions describe the exterior gravitational field produced by infinitely long rotating cylinders, and are useful models for global gravitational effects. When the metri…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
Hydrothermal Scheduling in the Continuous-Time Framework
Christian Øyn Naversen, Arild Helseth, Bosong Li +3
Continuous-time optimization models have successfully been used to capture the impact of ramping limitations in power systems. In this paper, the continuous-time framework is adapt…
The Gaia-ESO Survey: Carbon abundance in the Galactic thin and thick disks
Mariagrazia Franchini, Carlo Morossi, Paolo Di Marcantonio +24
This paper focuses on carbon that is one of the most abundant elements in the Universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution.…
Structural analysis of massive galaxies using HST deep imaging at z < 0.5
Sandra N. dos Reis, Fernando Buitrago, Polychronis Papaderos +11
Taking advantage of HST CANDELS data, we analyze the lowest redshift (z<0.5) massive galaxies in order to disentangle their structural constituents and study possible faint non-axi…
Decoding the radial velocity variations of HD41248 with ESPRESSO
J. P. Faria, V. Adibekyan, E. M. Amazo-Gómez +13
Twenty-four years after the discoveries of the first exoplanets, the radial-velocity (RV) method is still one of the most productive techniques to detect and confirm exoplanets. Bu…
Astrophysical and local constraints on string theory: runaway dilaton models
C. J. A. P. Martins, L. Vacher
One of the clear predictions of string theory is the presence of a dynamical scalar partner of the spin-2 graviton, known as the dilaton. This will violate the Einstein Equivalence…
The impact of atmospheric dispersion in the performance of high-resolution spectrographs
Bachar Wehbe, Alexandre Cabral, Jorge Martins +3
Differential atmospheric dispersion is a wavelength-dependent effect introduced by the atmosphere. It is one of the instrumental errors that can affect the position of the target a…
