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…
Dust production in the harsh environment of Sgr A* - MIRI/JWST observation of the O-rich asymptotic giant branch star IRS~3
F. Peißker, M. García Marín, A. Eckart +18
Studies of the interstellar medium (ISM) have frequently revealed signatures of the dust produced in the envelopes of asymptotic giant branch (AGB) stars, demonstrating a connectio…
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 PeiÃker +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…
Spatially resolved metallicity and ionization in the merging system Gz9p3 at z=9.3
Arjan Bik, Javier Ãlvarez-Márquez, Alejandro Crespo Gómez +26
Studying the interstellar medium (ISM) in merging high-redshift galaxies is crucial for understanding early galaxy assembly, star formation, and black hole growth, predicted by hie…
MIDIS: The identification of deep MIRI-red sources as candidates for extreme Balmer-break and line emitting galaxies at high-z
I. Jermann, G. Brammer, S. Gillman +27
We investigate the detection and nature of 5.6~μm MIRI-red sources in the MIRI Deep Imaging Survey (MIDIS), covering 2.4~arcmin in the Hubble Ultra Deep Field. MIDIS is the de…
Compact stellar systems hosting an intermediate mass black hole: magnetohydrodynamic study of inflow-outflow dynamics
Matúš Labaj, Sean M. Ressler, Michal ZajaÄek +3
Intermediate-mass black holes (IMBHs) are a missing link in black hole demographics, with only tentative observational evidence to date. Dense stellar clusters such as IRS 13E near…
