The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
The Villafranca catalog of Galactic OB groups: I. Systems with O2-O3.5 stars
J. Maíz Apellániz, P. Crespo Bellido, R. H. Barbá +2
CONTEXT. The GOSSS spectral classifications and Gaia data have significantly improved our ability to measure distances and determine memberships of stellar groups with OB stars. AI…
Detailed chemical composition and orbit of the new globular cluster FSR1758: Implications for the accretion of the Sequoia dwarf galaxy onto the Milky Way
Sandro Villanova, Lorenzo Monaco, Julia O'Connell +4
We present detailed chemical abundances, radial velocities and orbital parameters for FSR 1758, a recently discovered star cluster in the direction of the Galactic Bulge. High reso…
The First Galaxy Cluster Discovered by the VISTA Variables in the Vía Láctea Survey
L. D. Baravalle, J. L. Nilo Castellón, M. V. Alonso +12
We report the first confirmed detection of the galaxy cluster VVV-J144321-611754 at very low latitudes (l = 315.836, b = -1.650) located in the tile d015 of the…
A Sequoia in the Garden: FSR 1758 - Dwarf Galaxy or Giant Globular Cluster?
R. H. Barba, D. Minniti, D. Geisler +5
We present the physical characterization of FSR 1758, a new large, massive object very recently discovered in the Galactic Bulge. The combination of optical data from the 2nd Gaia…
First results from SAM-FP: Fabry-Perot observations with ground-layer adaptive optics - the structure and kinematics of the core of 30 Doradus
Claudia Mendes de Oliveira, Philippe Amram, Bruno Quint +3
The aim of this paper is to present the first data set obtained with SOAR Adaptive Module-Fabry-Parot (SAM-FP), a Fabry-Perot instrument mounted inside the SOAR telescope Adaptive-…
