SDSS-V Local Volume Mapper (LVM): The Integrated Light and Internal Rotation of Omega Centauri

Maximilian Häberle, Dmitry Bizyaev, Alina Boecker +34

The SDSS-V Local Volume Mapper (LVM) is a wide-field integral field spectroscopic survey of the Southern Milky Way plane, the Magellanic Clouds, and nearby Local Group galaxies. We…

Rotation and stability of the circumnuclear gas disk in the Galactic Center potential by the ALMA CMZ Exploration Survey (ACES)

Yoshiaki Sofue, Steven N. Longmore, Daniel Walker +26

We investigated the gravitational potential and mass distribution in the Galactic Center by examining the morphology and kinematics of the circumnuclear gaseous disk revealed by th…

SDSS-V LVM: Resolving Physical Conditions in the Trifid Nebula

Natascha Sattler, J. Eduardo Méndez-Delgado, Kathryn Kreckel +18

The chemical abundance of the interstellar medium sets the initial conditions for star formation and provides a probe of chemical galaxy evolution models. However, unresolved inhom…

The ALMA-QUARKS survey: Hot Molecular Cores are a long-standing phenomenon in the evolution of massive protostars

Dezhao Meng, Tie Liu, Jarken Esimbek +34

We present an analysis of the QUARKS survey sample, focusing on protoclusters where Hot Molecular Cores (HMCs, traced by CH3CN(12--11)) and UC HII regions (traced by H30α/H40α) c…

Nonthermal Pressures: Key to Energy Balance and Structure Formation Near Sgr A* in the Milky Way

Farideh Mazoochi, Fatemeh S. Tabatabaei, Ashley T. Barnes +14

The circumnuclear region of the Galactic Center offers a unique laboratory to study energy balance and structure formation around Sgr A. This work investigates thermal and n…
