The Mysterious Case of Iron in XMPs: Anomalous High log(Fe/O) Observed in Extremely Metal-Poor Galaxies HSCJ1631+4426 and SDSSJ0811+4730
Aaron Myszka, Themiya Nanayakkara, Karl Glazebrook +8
We present integral field spectroscopic observations of two local extremely metal-poor galaxies (XMPs), HSCJ1631+4426 and SDSSJ0811+4730, obtained with the Keck Cosmic Web Imager (…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
How can we finally see the first light? Status and perspective in the search for Population III stars
Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +28
Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…
Galactic Archaeology with the Subaru `Ånohi`ula Prime Focus Spectrograph Strategic Program
Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +47
The recently commissioned Subaru `Ånohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strate…
Mass-dependent chemical enrichment sequences of SDSS star-forming galaxies out to z~0.3 revealed by direct O & Ar abundances
Souradeep Bhattacharya, Magda Arnaboldi, Chiaki Kobayashi +2
Individual stars in the Milky Way (MW) and its satellites have been shown to trace galaxy stellar mass dependent sequences in the -abundance ([/Fe]) vs metallicity ([Fe/H])…
MARTA: The connection between chemical enrichment, feedback, and dust in a Wolf-Rayet galaxy at z2
Mirko Curti, Elisa Cataldi, Francesco Belfiore +17
We present the analysis of the stellar and interstellar medium (ISM) properties of MARTA-4327, a star-forming galaxy at z=2.224 observed by means of deep JWST/NIRSpec spectroscopy…
