Ionized and cold gas components in low surface brightness galaxy AGC 102004

Tian-Wen Cao, Zi-Jian Li, Pei-Bin Chen +7

We present the integral field spectroscopic observations of ionized gas (H and [{\ion{N}{II}}]) using the PCWI, along with deep CO(2-1) observations by the $^\backprime\bar{\rm…

High-Resolution Dayside Spectroscopy of WASP-189b: Detection of Iron during the GHOST/Gemini South System Verification Run

Emily K. Deibert, Adam B. Langeveld, Mitchell E. Young +30

With high equilibrium temperatures and tidally locked rotation, ultra-hot Jupiters (UHJs) are unique laboratories within which to probe extreme atmospheric physics and chemistry. I…

A high-resolution imaging survey of massive young stellar objects in the Magellanic Clouds

Venu M. Kalari, Ricardo Salinas, Hans Zinnecker +3

Constraints on the binary fraction of young massive stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs…
