Direct N-body simulations of globular clusters -- III. Palomar\,4 on an eccentric orbit
Akram Hasani Zonoozi, Hosein Haghi, Pavel Kroupa +2
Palomar 4 is a low-density globular cluster with a current mass in the outer halo of the Milky Way with a two-body relaxation time of the order of a Hubble…
Exploding Satellites -- The Tidal Debris of the Ultra-Faint Dwarf Galaxy Hercules
Andreas H. W. Küpper, Kathryn V. Johnston, Steffen Mieske +2
The ultra-faint satellite galaxy Hercules has a strongly elongated and irregular morphology with detections of tidal features up to 1.3 deg (3 kpc) from its center. This suggests t…
The effect of primordial mass segregation on the size scale of globular clusters
Hosein Haghi, Seyed Mohammad Hoseini-Rad, Akram Hasani Zonoozi +1
We use direct -body calculations to investigate the impact of primordial mass segregation on the size scale and mass-loss rate of star clusters in a galactic tidal field. We run…
Mass segregation in the outer halo globular cluster Palomar 14
Matthias J. Frank, Eva K. Grebel, Andreas H. W. Kuepper
We present evidence for mass segregation in the outer-halo globular cluster Palomar 14, which is intuitively unexpected since its present-day two-body relaxation time significantly…
Milky Way Mass and Potential Recovery Using Tidal Streams in a Realistic Halo
Ana Bonaca, Marla Geha, Andreas H. W. Kuepper +3
We present a new method for determining the Galactic gravitational potential based on forward modeling of tidal stellar streams. We use this method to test the performance of smoot…
Direct -body simulations of globular clusters - II. Palomar 4
Akram Hasani Zonoozi, Hosein Haghi, Andreas H. W. Kuepper +3
We use direct -body calculations to study the evolution of the unusually extended outer halo globular cluster Palomar 4 (Pal~4) over its entire lifetime in order to reproduce it…
