A binary system in the S cluster close to the supermassive black hole Sagittarius A*
Florian Peißker, Michal Zajacek, Lucas Labadie +4
High-velocity stars and peculiar G objects orbit the central supermassive black hole (SMBH) Sagittarius A* (Sgr A*). Together, the G objects and high-velocity stars constitute the…
Discovery of a Dense Association of Stars in the Vicinity of the Supermassive Black Hole Sgr A*
S. Elaheh Hosseini, Andreas Eckart, Michal Zajaček +3
We focus on a sample of 42 sources in the vicinity of the bow-shock source IRS 1W (N-sources), located at the distance of north-east of the supermassive black hole (SMBH)…
Dynamics of star associations in an SMBH-IMBH system: The case of IRS13 in the Galactic centre
Václav Pavlík, Vladimír Karas, Bhavana Bhat +2
Context: The existence of intermediate-mass black holes (IMBHs) still poses challenges to theoretical and observational astronomers. Several candidates have been proposed, includin…
The Evaporating Massive Embedded Stellar Cluster IRS 13 Close to Sgr A*. II. Kinematic structure
Florian Peißker, Michal Zajacek, Matus Labaj +8
The existence of two distinct and apparently unrelated populations of dusty stellar objects in the Nuclear Stellar Cluster (NSC) of the Milky Way, namely IRS 13 and the S-cluster,…
MICONIC: JWST/MIRI MRS observations of the nuclear and circumnuclear regions of Mrk231
A. Alonso-Herrero, L. Hermosa Muñoz, A. Labiano +22
We present JWST/MIRI MRS spatially resolved m observations of the central ~4-8kpc of the ultraluminous infrared galaxy and broad absorption line quasar Mrk231. These…
MIDIS. Near-infrared rest-frame morphology of massive galaxies at in the Hubble eXtreme Deep Field
L. Costantin, S. Gillman, L. A. Boogaard +29
Thanks to decades of observations using the Hubble Space Telescope (HST), the structure of galaxies at redshift has been widely studied in the rest-frame ultraviolet regime,…
