The local void model for the Hubble and BAO tensions

Indranil Banik, Harry Desmond, Vasileios Kalaitzidis +1

The inconsistency between the locally inferred Hubble constant and the value inferred from the cosmic microwave background assuming the CDM cosmological model has persisted, tu…

Intermediate-mass black hole incubators. Gas accretion onto stellar black hole clusters in galactic central molecular zones

Jaroslav Haas, Pavel Kroupa, Sergij Mazurenko

The stellar dynamical evolution of massive star clusters formed during starburst periods leads to the segregation of stellar-mass black hole sub-clusters in t…

The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics

Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533

The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…

The redshift dependence of the inferred in a local void solution to the Hubble tension

Sergij Mazurenko, Indranil Banik, Pavel Kroupa

Galaxy number counts suggest that we are located within the Gpc-scale KBC void. The Hubble tension might arise due to gravitationally driven outflow from this void, as explored in…

Open star clusters and their asymmetrical tidal tails

Pavel Kroupa, Jan Pflamm-Altenburg, Sergij Mazurenko +4

Stars that evaporate from their star cluster by the energy equipartition process end up either in a leading or a trailing tidal tail. In Newtonian gravitation and for open star clu…
