ACES VII. Compact Continuum Source Catalog of the Central Molecular Zone

Jennifer Wallace, Cara Battersby, Nazar Budaiev +58

The Central Molecular Zone (CMZ) resides in the inner few hundred parsecs of our Galaxy, and despite being the largest reservoir of dense molecular gas in the Milky Way, it has a r…

Theoretical emission lines and metallicity calibrations of H II regions in ASTRID simulation

Yao Yao, Kathryn Grasha, Stuart Wyithe +5

We present a theoretical framework to derive redshift-dependent metallicity calibrations for galaxies at =2-7. The ionization parameter () and gas pressure () in our appro…

Simultaneous Mars-orbit observations reveal Kelvin-Helmholtz instability-driven bulk atmospheric ion escape

Chi Zhang, Chuanfei Dong, Gangkai Poh +11

Atmospheric ion escape driven by the solar wind is a key process controlling the long-term loss of the Martian atmosphere. Localized plasma clouds can carry substantial fluxes of p…

The new era of Lyman alpha emitters (LAEs): Efficiency in the selection criteria

P. Layana-Astudillo, I. Laferte-Urrutia, L. Guaita +6

The ODIN survey has detected thousands of Lyman-alpha emitting galaxies across seven sky fields, covering nearly one hundred square degrees. One of these regions is the SHELA field…
