Does IRS13 require an intermediate-mass black hole?
Václav Pavlík, Vladimír Karas, Florian Peißker +2
We investigate whether the Galactic-centre association IRS13 requires an intermediate-mass black hole (IMBH) to remain bound. Using high-precision -body calculations of IRS13-li…
Dynamics of star associations in an SMBH-IMBH system: The case of IRS13 in the Galactic centre
Václav PavlÃk, VladimÃr Karas, Bhavana Bhat +2
Context: The existence of intermediate-mass black holes (IMBHs) still poses challenges to theoretical and observational astronomers. Several candidates have been proposed, includin…
Inference of black-hole mass fraction in Galactic globular clusters. A multi-dimensional approach to break the initial-condition degeneracies
A. Della Croce, F. I. Aros, E. Vesperini +4
Context. Globular clusters (GCs) are suggested to host many stellar-mass black holes (BHs) at their centers, thus resulting in ideal testbeds for BH formation and retention theorie…
New Parameters for Star Cluster Dynamics: the role of clusters initial conditions
Bhavana Bhat, Barbara Lanzoni, Enrico Vesperini +4
We recently introduced three new parameters that describe the shape of the normalized cumulative radial distribution (nCRD) of the innermost stars in globular clusters and trace th…
