Wandering intermediate-mass black holes and off-nuclear tidal disruption events from early star clusters
Claire E. Williams, Smadar Naoz, Yihao Zhou +9
Off-nuclear tidal disruption events (TDEs) reveal evidence for massive black holes outside galactic centers, but the origins of this wandering population remain uncertain. We inves…
A cosmological framework for stellar collisions at high redshift in proto-globular clusters, nuclear star clusters, and Little Red Dots
Claire E. Williams, Smadar Naoz, Sanaea C. Rose +8
Observations and cosmological simulations indicate that the early Universe hosted numerous compact, high-density stellar systems, where close encounters and physical collisions bet…
Observing compact Pop III star clusters and the presence of cosmic streaming
Claire E. Williams, Smadar Naoz, Naoki Yoshida +7
The formation of the Universe's first luminous stellar structures depends on the unique conditions at "Cosmic Dawn," which are set by the underlying cosmological model and early ba…
Studying Binary Systems in Omega Centauri with MUSE: II. Observational constraints on the orbital period distribution
S. Saracino, S. Kamann, F. Wragg +8
Omega Centauri ( Cen) is one of the most complex star clusters in the Milky Way, and likely the stripped nucleus of an accreted dwarf galaxy. Being the subject of debate between…
