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…
Rigorous results in space-periodic two-dimensional turbulence
Sergei Kuksin, Armen Shirikyan
We survey the recent advance in the rigorous qualitative theory of the 2d stochastic Navier-Stokes system that are relevant to the description of turbulence in two-dimensional flui…
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…
Modelling of an actuated elastic swimmer
Miguel Piñeirua, Benjamin Thiria, Ramiro Godoy-Diana
We study the force production dynamics of undulating elastic plates as a model for fish-like inertial swimmers. Using a beam model coupled with Lighthill's large-amplitude elongate…
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…
