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…

Candidate Young Stellar Objects in the S-cluster: The Kinematic Analysis of a Sub-population of the Low-mass G-objects close to Sgr A*
Florian PeiÃker, Michal ZajaÄek, Maria Melamed +5
The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty ob…
