Update on Dusty Sources and Candidate Young Stellar Objects in the S-cluster
Maria Melamed, Florian Peißker
The Galactic Center provides a unique opportunity to observe a galactic core, objects in close proximity to a supermassive black hole (SMBH), and star formation channels that exhib…
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…
Galactic center G objects as dust-enshrouded stars near the supermassive black hole
Michal Zajaček, Monika Pikhartová, Florian Peissker
In this contribution, we revisit the model of a dust-enshrouded star orbiting a low-luminosity galactic nucleus (Zajaček et al. 2014, 2016, 2017). Although it is quite challenging…
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,…
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,…
JWST/MIRI unveils the stellar component of the GN20 dusty galaxy overdensity at =4.05
A. Crespo Gómez, L. Colina, J. Álvarez-Márquez +24
Despite the importance of the dusty star-forming galaxies (DSFGs) at >2 for understanding the galaxy evolution in the early Universe, their stellar distributions traced by the n…
