The Evaporating Massive Embedded Stellar Cluster IRS 13 Close to Sgr A*. I. Detection of a rich population of dusty objects in the IRS 13 cluster
Florian Peißker, Michal Zajaček, Lauritz Thomkins +6
A detailed analysis of the Nuclear Stellar Cluster (NSC) concedes not only the existence of the Scluster with its fast-moving stars and the supermassive black hole (SMBH) Sgr A*. I…
First rest-frame infrared spectrum of a z>7 quasar: JWST/MRS observations of J1120+0641
Sarah E. I. Bosman, Javier Álvarez-Márquez, Luis Colina +29
We present a JWST/MRS spectrum of the quasar J1120+0641 at z=7.0848, the first spectroscopic observation of a reionisation-era quasar in the rest-frame infrared (m). In…
Uncovering the stellar structure of the dusty star-forming galaxy GN20 at z=4.055 with MIRI/JWST
L. Colina, A. Crespo Gómez, J. Álvarez-Márquez +35
Luminous infrared galaxies at high redshifts (>4) include extreme starbursts that build their stellar mass over short periods of time (>100 Myr). These galaxies are considered t…
X3: a high-mass Young Stellar Object close to the supermassive black hole Sgr~A*
Florian Peißker, Michal Zajacek, Nadeen B. Sabha +10
To date, the proposed observation of Young Stellar Objects (YSOs) in the Galactic center (GC) still raises the question where and how these objects could have formed due to the vio…
Observation of S4716 -- a Star with a 4 yr Orbit around Sgr A*
Florian Peißker, Andreas Eckart, Michal Zajaček +1
The ongoing monitoring of the Galactic center and Sgr A*, the central supermassive black hole, produces surprising and unexpected findings. This goes hand in hand with the technica…
The apparent tail of the Galactic center object G2/DSO
Florian Peißker, Michal Zajacek, Andreas Eckart +6
The observations of the near-infrared excess object G2/DSO induced an increased attention towards the Galactic center and its vicinity. The predicted flaring event in 2014 and the…
