Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Northern Local Star-forming Dwarf Galaxies. Analogues of the First Galaxies and Probes of the Cosmic Metallicity Scale
C. Esteban, J. M. Vilchez, J. García-Rojas +15
Star-forming dwarf galaxies in the local Universe, especially extremely metal-poor ones, can be considered analogous to early galaxies of the Epoch of Reionization (z >= 6). Curren…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
The EDGE-CALIFA Survey: Influence of Mergers on Radial Profiles of Star-Formation Properties
Y. Garay-Solis, J. K. Barrera-Ballesteros, L. Carigi +6
In this study, we investigate how the merging process influences the radial variations of the specific Star Formation Rate (sSFR), Star Formation Efficiency (SFE), and molecular ga…
Atmospheric parameters and chemical abundances of young stars with APOGEE. I. Orion star-forming region
Ricardo López-Valdivia, Lucía Adame, Carlos G. Román-Zúñiga +19
We derive atmospheric parameters and chemical abundances in young G-, K-, and M-type stars (temperatures between 6500 and 3100 K) using infrared APOGEE-2 spectra. Atmospheric param…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
Physical properties of HII regions at sub-kpc scales using integral field spectroscopy on IC 342
J. K. Barrera-Ballesteros, S. F. Sanchez, K. Kreckel +7
In this study we use Integral Field Spectroscopic (IFS) observations for one of the closest galaxy to us, the grand design spiral IC 342, to derive physical properties of HII regio…
Alpha-element abundance patterns in star-forming regions of the local Universe
C. Esteban, J. E. Méndez-Delgado, J. García-Rojas +6
(Abridged) We reassess the alpha-element abundance ratios (Ne/O, S/O, Ar/O) with respect to metallicity in ~1000 spectra of Galactic and extragalactic HII regions and star-forming…
