A family of scalar-Einstein and vacuum Brans-Dicke axisymmetric solutions
Bertrand Chauvineau
A new method is proposed, that establishes a one to one correspondance between the whole set of static axially symmetric vacuum GR solutions and a specific class of stationary axia…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Molecular gas in radio galaxies in dense Mpc-scale environments at
G. Castignani, F. Combes, P. Salomé +4
We investigate the role of dense Mpc-scale environment in processing molecular gas in distant Low luminosity radio galaxies (LLRGs) in galaxy (proto-)clusters. We have selected wit…
Large-Scale Velocity Dispersion and the Cosmic Web
Michael Buehlmann, Oliver Hahn
Gravitational collapse in cosmological context produces an intricate cosmic web of voids, walls, filaments and nodes. The anisotropic nature of collisionless collapse leads to the…
Semiclassical path to cosmic large-scale structure
Cora Uhlemann, Cornelius Rampf, Mateja Gosenca +1
We chart a path toward solving for the nonlinear gravitational dynamics of cold dark matter by relying on a semiclassical description using the propagator. The evolution of the pro…
The signatures of the resonances of a large Galactic bar in local velocity space
Giacomo Monari, Benoit Famaey, Arnaud Siebert +2
The second data release of the Gaia mission has revealed a very rich structure in local velocity space. In terms of in-plane motions, this rich structure is also seen as multiple r…
