I present an overview of the main observational properties of Blue Straggler Stars(BSSs)in Galactic Globular Clusters(GCs)in the framework of using this “exotic” stellar population as probe of GC internal dynamics.In particular,the shape of the BSS radial distribution has been found to be a powerful tracer of the dynamical age of stellar systems,thus allowing the definition of the first empirical “dynamical clock”.

Almost all galaxies along the Hubble sequence host a Compact Massive Object in their center,in the form of either a supermassive black hole(SMBH)or a very dense stellar cluster(commonly referred to as
Nuclear stellar clusters(NSCs)are known to exist around massive black holes(MBHs)in galactic nuclei.The properties of these extremely dense clusters are strongly related to the MBH they host,and both
Shakura-Sunyaev,slim,thick and adaf accretion disk models provide an analytic paradigm for understanding the black hole accretion phenomenon.I will describe the physical and mathematical foundations o
The H2O megamaser technique provides a unique method to directly image the subparsec scale gas disks around the supermassive black hole(BH)at the center of active galaxies.These well-ordered Keplerian
I review the evolution of binary supermassive black holes and focus on the stellardynamical mechanisms that may help to overcome the final-parsec problem – the possible stalling of the binary at a sep
Dynamical interactions that take place between objects in dense stellar systems lead to frequent formation of exotic stellar objects,unusual binaries,and systems of higher multiplicity.They are most i
With a focus on the results of direct N-body simulations performed on GRAPE and GPU special-purpose hardware,the current status of models applicable to studying globular cluster evolution will be revi
Even though globular clusters(GCs)have long been considered prototypical simple spherical systems,their origin is still strongly debated.Internal kinematics,acting as fossil record of the formation pr
It is widely accepted that the distribution function of the masses of young star clusters is universal and can be purely interpreted as a probability density distribution function with a constant uppe
