ACACIAS II: element abundances for 39 stars in the dwarf galaxy Sculptor
Anell Cornejo-Cárdenas, Sven Buder, Melissa K. Ness +1
Element abundances in nearby galaxies provide insights into their chemical enrichment histories and place the Milky Way and its neighbours in a broader cosmological context. These…
Barium and europium abundances from the Gaia-ESO Survey using The Cannon
Pradosh Barun Das, Francesca Primas, Gayandhi De Silva +3
Neutron-capture element abundances encode the time-dependent interplay between slow (s-) and rapid (r-) nucleosynthetic processes and provide critical constraints on Galactic chemi…
Star Cluster Populations in 38 Spiral Galaxies: Evidence for Near-Universal Mass and Age Distributions from PHANGS
Rupali Chandar, Matthew R. Floyd, David A. Thilker +23
We present the largest study to date of star cluster mass and age distributions in nearby galaxies. The analysis is based on a uniformly selected catalog of over 15,000 (36,000) hu…
The assembly history of NGC 1365 through chemical archaeology
Lisa J. Kewley, Kathryn Grasha, Alex Garcia +8
Galaxies build through infalling gas and galaxy mergers. Tracking the dynamical history of a galaxy from a single snapshot in time is notoriously difficult. We show that the dynami…
Detecting HI Self-Absorption using Neural Networks
Eric G. M. Muller, Naomi M. McClure-Griffiths, Hiep Nguyen +5
Cold atomic hydrogen plays a crucial role in the life cycle of interstellar gas. It serves as the intermediary phase in the condensation and cooling processes that bridge the warm…
The Delegate Survey: KOALA/AAOmega-IFU spectroscopy of three nearby dwarf galaxies
Kyungdo Ko, Helmut Jerjen, Sarah M. Sweet +6
Assessing the cosmological typicality of the Local Group is crucial for establishing whether its dwarf galaxy population is representative. To this end, the Delegate Survey targets…
