The Orbital Structure and Selection Effects of the Galactic Center S-star Cluster

Autor: A. Burkert, S. Gillessen, D. N. C. Lin, X. Zheng, P. Schoeller, F. Eisenhauer, R. Genzel

Publikováno v: The Astrophysical Journal, Vol 962, Iss 1, p 81 (2024)

The orbital distribution of the S-star cluster surrounding the supermassive black hole in the center of the Milky Way is analyzed. A tight dependence of the pericenter distance r _p on orbital eccentricity e _⋆ is found, $\mathrm{log}({r}_{{\rm{p}}

Evidence for Large-scale, Rapid Gas Inflows in z ∼ 2 Star-forming Disks

Publikováno v: The Astrophysical Journal, Vol 957, Iss 1, p 48 (2023)

We report high-quality H α /CO imaging spectroscopy of nine massive (log median stellar mass = 10.65 M _⊙ ) disk galaxies on the star-forming main sequence (henceforth SFGs), near the peak of cosmic galaxy evolution ( z ∼ 1.1–2.5), taken with

The Accretion Mode in Sub-Eddington Supermassive Black Holes: Getting into the Central Parsecs of Andromeda

Autor: C. Alig, A. Prieto, M. Blaña, M. Frischman, C. Metzl, A. Burkert, O. Zier, A. Streblyanska

Publikováno v: The Astrophysical Journal, Vol 953, Iss 1, p 109 (2023)

The inner kiloparsec regions surrounding sub-Eddington (luminosity less than 10 ^−3 in Eddington units, L _Edd ) supermassive black holes (BHs) often show a characteristic network of dust filaments that terminate in a nuclear spiral in the central

A Comprehensive Study on the Relation between the Metal Enrichment of Ionized and Atomic Gas in Star-forming Galaxies

Autor: M. Arabsalmani, L. Garratt-Smithson, N. Wijers, J. Schaye, A. Burkert, C. D. P. Lagos, E. Le Floc’h, D. Obreschkow, C. Peroux, B. Schneider

Publikováno v: The Astrophysical Journal, Vol 952, Iss 1, p 67 (2023)

We study the relation between the metallicities of ionized and atomic gas in star-forming galaxies at z = 0–3 using the Evolution and Assembly of GaLaxies and their Environments (EAGLE) cosmological, hydrodynamical simulations. This is done by cons

An ∼600 pc View of the Strongly Lensed, Massive Main-sequence Galaxy J0901: A Baryon-dominated, Thick Turbulent Rotating Disk with a Clumpy Cold Gas Ring at z = 2.259

Publikováno v: The Astrophysical Journal, Vol 942, Iss 2, p 98 (2023)

We present a high-resolution kinematic study of the massive main-sequence star-forming galaxy (SFG) SDSS J090122.37+181432.3 (J0901) at z = 2.259, using ∼0.″36 Atacama Large Millimeter/submillimeter Array CO(3–2) and ∼0.″1–0.″5 SINFONI/

RC100: Rotation Curves of 100 Massive Star-forming Galaxies at z = 0.6–2.5 Reveal Little Dark Matter on Galactic Scales

Publikováno v: The Astrophysical Journal, Vol 944, Iss 1, p 78 (2023)

We analyze H α or CO rotation curves extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy star formation ( z ∼ 0.6–2.5), more than doubling the previous sample
