The Bulge Metallicity Distribution from the APOGEE Survey
Ana E. Garcia Perez, Melissa Ness, Annie C. Robin +14
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) provides spectroscopic information of regions of the inner Milky Way inaccessible to optical surveys. We present…
Dynamical equivalence, the origin of the Galactic field stellar and binary population, and the initial radius--mass relation of embedded clusters
Diogo Belloni, Pavel Kroupa, Helio J. Rocha-Pinto +1
In order to allow a better understanding of the origin of Galactic field populations, dynamical equivalence of stellar-dynamical systems has been postulated by Kroupa and Belloni e…
Bulgeless galaxies in the COSMOS field: environment and star formation evolution at
M. Grossi, C. A. C. Fernandes, D. Sobral +5
Combining the catalogue of galaxy morphologies in the COSMOS field and the sample of H emitters at redshifts and of the HiZELS survey, we selected 220 st…
The MUSE 3D view of feedback in a high-metallicity radio galaxy at z = 2.9
M. Silva, A. Humphrey, P. Lagos +8
We present a detailed study of the kinematic, chemical and excitation properties of the giant Ly emitting nebula and the giant \ion{H}{I} absorber associated with the …
Disentangling the Galactic Halo with APOGEE: I. Chemical and Kinematical Investigation of Distinct Metal-Poor Populations
Christian R. Hayes, Steven R. Majewski, Matthew Shetrone +21
We find two chemically distinct populations separated relatively cleanly in the [Fe/H] - [Mg/Fe] plane, but also distinguished in other chemical planes, among metal-poor stars (pri…
The first 62 AGN observed with SDSS-IV MaNGA - I: their characterization and definition of a control sample
Sandro B. Rembold, Jáderson S. Shimoia, Thaisa Storchi-Bergmann +16
We report the characterization of the first MaNGA Active Galactic Nuclei (AGN) hosts in the Fifth Product Launch (MPL-5) and the definition of a control sample of non-active g…
