Direct imaging of AGN outflows and their origin with the 23 m Large Binocular Telescope
Jacob W. Isbell, Steve Ertel, Jörg-Uwe Pott +17
Active galactic nuclei (AGNs) are a key component of galaxy evolution due to feedback on the host from its supermassive black hole. The morphology of warm, in- and outflowing dusty…
The Pristine survey. XXVI. Chemical abundances of subgiant stars of the extremelymetal-poor stream C-19
P. Bonifacio, E. Caffau, P. François +17
Context: The C-19 stellar stream is the most metal-poor stream known to date. While its width and velocity dispersion indicate a dwarf galaxy origin, its metallicity spread and abu…
The ALPINE-ALMA [CII] Survey: Modelling ALMA and JWST lines to constrain the interstellar medium of galaxies
E. Veraldi, L. Vallini, F. Pozzi +13
In this work, we devise a model for estimating UV and optical line emission (i.e., CIII] A, H, [OIII] A, H, [NII] A) tracing HII regions in the interstellar…
Metallicity-dependent kinematics and orbits in the Milky Way's nuclear stellar disc
F. Nogueras-Lara, N. Nieuwmunster, M. Schultheis +7
The nuclear stellar disc (NSD) is a flat and dense stellar structure at the centre of the Milky Way. Previous work has identified the presence of metal-rich and metal-poor stars in…
The ALMA-ALPAKA survey II. Evolution of turbulence in galaxy disks across cosmic time: difference between cold and warm gas
F. Rizzo, C. Bacchini, M. Kohandel +8
The gas in the interstellar medium (ISM) of galaxies is supersonically turbulent. Measurements of turbulence typically rely on cold gas emission lines for low-z galaxies and warm i…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
