Exo-Milankovitch Cycles I: Orbits and Rotation States
Russell Deitrick, Rory Barnes, Thomas R. Quinn +3
The obliquity of the Earth, which controls our seasons, varies by only ~2.5 degrees over ~40,000 years, and its eccentricity varies by only ~0.05 over 100,000 years. Nonetheless, t…
Rotationally-resolved spectroscopy of Jupiter Trojans (624) Hektor and (911) Agamemnon
Davide Perna, Nicolas Bott, Tetiana Hromakina +3
We present the first-ever rotationally resolved spectroscopic investigation of (624) Hektor and (911) Agamemnon, the two largest Jupiter Trojans. The visible and near-infrared spec…
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…
Henri Bénard: Thermal convection and vortex shedding
J. E. Wesfreid
We present in this article the work of Henri Bénard (1874-1939), French physicist who began the systematic experimental study of two hydrodynamic systems: the thermal convection of…
Studying the transfer of magnetic helicity in solar active regions with the connectivity-based helicity flux density method
K. Dalmasse, E. Pariat, G. Valori +2
In the solar corona, magnetic helicity slowly and continuously accumulates in response to plasma flows tangential to the photosphere and magnetic flux emergence through it. Analyzi…
Photometric observations of nine Transneptunian objects and Centaurs
T. Hromakina, D. Perna, I. Belskaya +3
We present the results of photometric observations of six Transneptunian objects and three Centaurs, estimations of their rotational periods and corresponding amplitudes. For six o…
HD 156324: a tidally locked magnetic triple spectroscopic binary with a disrupted magnetosphere
M. Shultz, Th. Rivinius, G. A. Wade +3
HD 156324 is an SB3 (B2V/B5V/B5V) system in the Sco OB4 association. The He-strong primary possesses both a strong magnetic field, and H emission believed to originate in its Ce…
An X-ray survey of the central molecular zone: variability of the Fe Ka emission line
R. Terrier, M. Clavel, S. Soldi +4
There is now abundant evidence that the luminosity of the Galactic super-massive black hole (SMBH) has not always been as low as it is nowadays. The observation of varying non-ther…
Uniform generation of infinite concurrent runs: the case of trace monoids
Samy Abbes, Vincent Jugé
We introduce an algorithm for the uniform generation of infinite runs in concurrent systems under a partial order probabilistic semantics. We work with trace monoids as concurrency…
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…
On the Progenitor of Binary Neutron Star Merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1095
On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB 170817A), and…
On the motion of hairy black holes in Einstein-Maxwell-dilaton theories
Félix-Louis Julié
Starting from the static, spherically symmetric black hole solutions in massless Einstein-Maxwell-dilaton (EMD) theories, we build a "skeleton" action, that is, we phenomenological…
Scientific Synergy Between LSST and Euclid
Jason Rhodes, Robert C. Nichol, Éric Aubourg +34
Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high cadence, deep, wid…
TeV gamma-ray observations of the binary neutron star merger GW170817 with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +250
We search for high-energy gamma-ray emission from the binary neutron star merger GW170817 with the H.E.S.S. Imaging Air Cherenkov Telescopes. The observations presented here have b…
