The Actinide-Boost Star LAMOST J122216.85-063345.2: A Detailed R-process Abundance Study with Gemini-S/GHOST
Miji Jeong, Young Sun Lee, Vinicius M. Placco +15
We present a detailed chemical-abundance analysis of an actinide-boost ((Th/Dy) = -0.74) star, LAMOST J122216.85-063345.2 (J1222), a very metal-poor ([Fe/H] = -2.45) halo st…
Formation of A Nuclear Star Cluster Through A Merger Event In The Low Surface Brightness Galaxy AGC 223218
Tian-Wen Cao, Zi-Qi Chen, Zi-Jian Li +8
We present the properties of the nuclear star cluster (NSC) in the low surface brightness galaxy AGC 223218. The disk of the galaxy can be modeled using two Srsic co…
Ionized gas components in low surface brightness galaxy AGC 111629
Tian-Wen Cao, Pei-Bin Chen, Zi-Jian Li +8
We present integral field spectroscopy of ionized gas components in AGC 111629, an edge-on low surface brightness galaxy (LSBG) with a stellar mass of 5.710 M$_{\odot…
Dense clumps survive in the vicinity of R136 in 30 Doradus
M. T. Valdivia-Mena, M. Rubio, V. M. Kalari +5
Context: The young massive cluster R136 at the center of 30 Doradus (30 Dor) in the Large Magellanic Cloud (LMC) generates a cavity in the surrounding molecular cloud. However, the…
GHOST commissioning science results -- IV: Chemodynamical analyses of Milky Way satellites Sagittarius II and Aquarius II
Daria Zaremba, Kim Venn, Christian R. Hayes +28
We present Gemini/GHOST high-resolution spectra of five stars observed in two low surface brightness Milky Way satellites, Sagittarius II (Sgr2) and Aquarius II (Aqu2). For Aqu2, t…
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…
