The contribution to Galactic Centre γ-ray excess from cluster-born millisecond pulsars. Constraints from direct N-body simulations
M. Kalambay, M. Ishchenko, D. Kuvatova +2
The Galactic Centre γ-ray excess (GCE), observed by Fermi-LAT around Sgr A*, exceeds expectations from standard cosmic-ray models and is commonly attributed either to dark matter…

Dynamical model of Praesepe and its tidal tails
L. Weis, C. West, A. Just +5
Context. The dynamical evolution of open clusters in the tidal field of the Milky Way and the feeding of the disc field star population depend strongly on the initial conditions at…

Global survey of star clusters in the Milky Way VIII. Cluster formation and evolution
Jonathan H. Klos, Andreas Just, Evgeny V. Polyachenko +2
We consider tidal masses and ages of Milky Way open clusters, as well as a simple model of their distribution. Our aim is to investigate the space of model parameters and the corre…
