Instabilities in disc galaxies: from noise to grooves to spirals
Sven De Rijcke, Jean-Baptiste Fouvry, Christophe Pichon
Using the linearized Boltzmann equation, we investigate how grooves carved in the phase space of a half-mass Mestel disc can trigger the vigorous growth of two-armed spiral eigenmo…

How gravitational softening affects galaxy stability I. Linear mode analysis of disc galaxies
Sven De Rijcke, Jean-Baptiste Fouvry, Walter Dehnen
Linear perturbation is used to investigate the effect of gravitational softening on the retrieved two-armed spiral eigenmodes of razor-thin stellar discs. We explore four softening…

Extended stellar systems in the solar neighborhood - I. The tidal tails of the Hyades
Stefan Meingast, João Alves
We report the discovery of two well-defined tidal tails emerging from the Hyades star cluster. The tails were detected in Gaia DR2 data by selecting cluster members in the three-di…
