The Nearest Galactic Nucleus: Studying the Galactic Centre with SKA-Mid
Rainer Schoedel, Antxon Alberdi, Izaskun Jiménez-Serra +24
The Galactic Centre is the nearest nucleus of a galaxy and the most extreme environment that we can observe down to physical scales of a few hundred astronomical units. There is no…
The flaring drill in the Galactic centre. Did the IRS 13 cluster carve out the mini-cavity in the mini-spiral?
Jaroslav Haas, Pavel Kroupa, Florian Peißker +1
The mini-cavity is a low-density region observed in the complex of streams of ionized gas around the Galactic central supermassive black hole, Sgr A, known as the mini-spir…
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 star grinder in the Galactic centre. Uncovering the highly compact central stellar-mass black hole cluster
Jaroslav Haas, Pavel Kroupa, Ladislav Šubr +1
Various past theoretical considerations and observational efforts suggest the presence of a population of stellar-mass black holes in the innermost parsec of the Galactic centre. I…
Failed supernova explosions increase the duration of star formation in globular clusters
Henriette Wirth, Jaroslav Haas, Ladislav Šubr +3
Context. The duration of star formation (SF) in globular clusters (GCs) is an essential aspect for understanding their formation. Contrary to previous presumptions that all stars a…
