Unveiling the 3D structure of the central molecular zone from stellar kinematics and photometry: The 50 and 20 km/s clouds
Francisco Nogueras-Lara, Ashley T. Barnes, Jonathan D. Henshaw +25
The central molecular zone (CMZ), surrounding the Galactic centre, is the largest reservoir of dense molecular gas in the Galaxy. Despite its relative proximity, the 3D structure o…
ACES: The Magnetic Field in Large Filaments in the Galactic Center
Dylan M. Paré, Zi-Xuan Feng, Yue Hu +33
The Galactic Center (GC) is an extreme region of the Milky Way that is host to a complex set of thermal and non-thermal structures. In particular, the GC contains high-density gas…
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…
Chemical templates of the Central Molecular Zone. Shock and protostellar object signatures under Galactic Center conditions
Katarzyna M. Dutkowska, Gijs Vermariën, Serena Viti +21
(Abridged) The Central Molecular Zone (CMZ) of the Milky Way exhibits extreme conditions, including high gas densities, elevated temperatures, enhanced cosmic-ray ionization rates,…
Circum-nuclear eccentric gas flow in the Galactic Center revealed by ALMA CMZ Exploration Survey (ACES)
Yoshiaki Sofue, Tomoharu Oka, Steven N. Longmore +41
We analyze the CS (J=2-1) line cube from the internal data release obtained by the large-scale program "ALMA CMZ Exploration Survey (ACES)" to investigate the kinematic structure o…
A broad linewidth, compact, millimeter-bright molecular emission line source near the Galactic Center
Adam Ginsburg, John Bally, Ashley T. Barnes +37
A compact source, G0.02467-0.0727, was detected in ALMA \threemm observations in continuum and very broad line emission. The continuum emission has a spectral index ,…
