Stellar winds near massive black holes: The case of the S-stars
Nora Lützgendorf, Edwin van der Helm, Inti Pelupessy +1
The Galactic center provides a unique laboratory to study the interaction of a supermassive black hole (SMBH) with its gaseous and stellar environment. Simulations to determine the…
Anomalous Microwave Emission in HII regions: is it really anomalous? The case of RCW 49
Roberta Paladini, Adriano Ingallinera, Claudia Agliozzo +5
The detection of an excess of emission at microwave frequencies with respect to the predicted free-free emission has been reported for several Galactic HII regions. Here, we invest…
KMOS view of the Galactic Centre I. Young stars are centrally concentrated
A. Feldmeier-Krause, N. Neumayer, R. Schödel +7
The Galactic centre hosts a crowded, dense nuclear star cluster with a half-light radius of 4 pc. Most of the stars in the Galactic centre are cool late-type stars, but there are a…
CARMA Observations of Galactic Cold Cores: Searching for Spinning Dust Emission
C. T. Tibbs, R. Paladini, K. Cleary +9
We present the first search for spinning dust emission from a sample of 34 Galactic cold cores, performed using the CARMA interferometer. For each of our cores we use photometric d…
Detection of satellite remnants in the Galactic Halo with Gaia III. Detection limits for Ultra Faint Dwarf Galaxies
Teresa Antoja, Cecilia Mateu, Luis Aguilar +8
We present a method to identify Ultra Faint Dwarf Galaxy (UFDG) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its detection limits and comp…
A re-evaluation of the central velocity-dispersion profile in NGC 6388
Nora Lützgendorf, Karl Gebhardt, Holger Baumgardt +4
Recently, two independent groups found very different results when measuring the central velocity dispersion of the galactic globular cluster NGC 6388 with different methods. While…
