Near-Infrared Spectroscopy with IGRINS-2 for Studying Multiple Stellar Populations in Globular Clusters
Dongwook Lim, Young-Wook Lee, Sol Yun +53
Recent advancements in near-infrared (NIR) spectroscopy have opened new opportunities for studying multiple stellar populations in globular clusters (GCs), particularly for newly d…
GHOST Commissioning Science Results: Identifying a new chemically peculiar star in Reticulum II
Christian R. Hayes, Kim A. Venn, Fletcher Waller +79
The Gemini High-resolution Optical SpecTrograph (GHOST) is the newest high resolution spectrograph to be developed for a large aperture telescope, recently deployed and commissione…
Spectroscopic Study of Extended Star Clusters in Dwarf Galaxy NGC 6822
Narae Hwang, Hong Soo Park, Myung Gyoon Lee +5
We present a spectroscopic study of the four extended star clusters (ESCs) in NGC 6822 based on the data obtained with Gemini Multi-Object Spectrograph (GMOS) on the Gemini-South 8…
The GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) II: Characterization of 47 Tuc with Bayesian Statistics
Mirko Simunovic, Thomas H. Puzia, Bryan Miller +5
We present a photometric analysis of globular cluster 47 Tuc (NGC\,104), using near-IR imaging data from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) which is in operatio…
Gemini Spectra of Star Clusters in the Spiral Galaxy M101
Lesley A. Simanton-Coogan, Rupali Chandar, Bryan Miller +1
We present low resolution, visible light spectra of 41 star clusters in the spiral galaxy M101, taken with the Gemini/GMOS instrument. We measure Lick indices for each cluster and…
An Early Look at the Performance of IGRINS-2 at Gemini-North with Application to the ultrahot Jupiter, WASP-33 b
Yeon-Ho Choi, Ueejeong Jeong, Jae-Joon Lee +56
Ground-based high-resolution spectroscopy enables precise molecular detections and velocity-resolved atmospheric dynamics, offering a distinct advantage over low-resolution methods…
