An evolutionary continuum from nucleated dwarf galaxies to star clusters
Kaixiang Wang, Eric W. Peng, Chengze Liu +21
Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii of approximately 10-100 parsecs and stellar mas…
Testing the Surface Brightness Fluctuation Method on Dwarf Galaxies in the COSMOS Field
Lauren M. Foster, James E. Taylor, John P. Blakeslee
Dwarf galaxies are important tracers of small-scale cosmological structure, yet much of our knowledge about these systems comes from the limited sample of dwarf galaxies within the…
The Chemodynamical Nature of the Triangulum-Andromeda Overdensity
Yuri Abuchaim, Hélio D. Perottoni, Silvia Rossi +7
We present a chemodynamical study of the Triangulum-Andromeda overdensity (TriAnd) employing a sample of 31 candidate stars observed with the GRACES high-resolution (=40,000) sp…
Search for Extremely Metal-Poor Stars with GEMINI-N/GRACES I. Chemical-Abundance Analysis
Miji Jeong, Young Sun Lee, Timothy C. Beers +5
We present stellar parameters and abundances of 13 elements for 18 very metal-poor (VMP; [Fe/H] -2.0) stars, selected as extremely metal-poor (EMP; [Fe/H] -3.0) candidates…
MUSE crowded field 3D spectroscopy in NGC 300 : IV. Planetary nebula luminosity function
Azlizan A. Soemitro, Martin M. Roth, Peter M. Weilbacher +5
We perform a deep survey of planetary nebulae (PNe) in the spiral galaxy NGC 300 to construct its planetary nebula luminosity function (PNLF). We aim to derive the distance using t…
Reconstructing and Classifying SDSS DR16 Galaxy Spectra with Machine-Learning and Dimensionality Reduction Algorithms
Felix Pat, Stéphanie Juneau, Vanessa Böhm +6
Optical spectra of galaxies and quasars from large cosmological surveys are used to measure redshifts and infer distances. They are also rich with information on the intrinsic prop…
