A Newly Discovered VVVX Star Cluster Surfing the Galactic Disk
Elisa R. Garro, José G. Fernández-Trincado, Casmir O. Obasi +15
We report the discovery of Garro 04, a previously unidentified stellar cluster toward the Galactic disc, uncovered as part of the ESO/KMOS VVVX-GalCen Spectroscopic Survey. This ob…
Phosphorous in the moderately metal-poor bulge globular clusters NGC 6539 and NGC 6569
Morgan S. Camargo, Beatriz Barbuy, Heitor Ernandes +10
The distinct stellar populations of the Galactic bulge can be disentangled through detailed analysis of their chemical abundances and kinematical properties. Recent studies have su…
SDSS-V Local Volume Mapper (LVM): The Integrated Light and Internal Rotation of Omega Centauri
Maximilian Häberle, Dmitry Bizyaev, Alina Boecker +34
The SDSS-V Local Volume Mapper (LVM) is a wide-field integral field spectroscopic survey of the Southern Milky Way plane, the Magellanic Clouds, and nearby Local Group galaxies. We…
An Exploratory Analysis of New Large Gaia-informed Quasar Samples in SDSS-V
Shir Aviram, Benny Trakhtenbrot, Tom Dwelly +22
Quasars are luminous objects that provide insights into the physics and evolution of supermassive black holes (SMBHs) and their accretion flows, galaxy evolution, and even cosmolog…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
SDSS-V Local Volume Mapper (LVM): Revealing the Structure of the Rosette Nebula
Mónica A. Villa-Durango, Jorge Barrera-Ballesteros, Carlos G. Román-Zúñiga +19
The Rosette Nebula is a well-known H II region shaped by the interaction of gas with the OB stars of the NGC 2244 stellar association. Located within the remnant of a giant molecul…
CAPOS: the bulge Cluster APOgee Survey IX. Spectroscopic Analysis of the Bulge Globular Cluster Terzan 2
Macarena Uribe, Sandro Villanova, Douglas Geisler +5
We present the first detailed spectroscopic analysis of the heavily extincted bulge globular cluster Terzan 2 (Ter 2) based on high-resolution near-infrared spectra obtained as par…
APOGEE-2S view of the globular cluster Patchick 125 (Gran 3). New metallicity and elemental abundances from high-resolution spectroscopy
José G. Fernández-Trincado, Dante Minniti, Elisa R. Garro +1
We present detailed elemental abundances, radial velocity, and orbital elements for Patchick~125, a recently discovered metal-poor globular cluster (GC) in the direction of the Gal…
The HST large programme on Centauri -- III. Absolute proper motion
M. Libralato, A. Bellini, L. R. Bedin +11
In this paper we report a new estimate of the absolute proper motion (PM) of the globular cluster NGC 5139 ( Cen) as part of the HST large program GO-14118+14662. We analyzed a…
Abundance anomalies in red giants with possible extragalactic origins unveiled by APOGEE-2
J. G. Fernández-Trincado, D. Geisler, E. Moreno +3
By performing an orbital analysis within a Galactic model including a bar, we found that it is plausible that the newly discovered stars that show enhanced Al and N accompanied by…
The DR14 APOGEE-TGAS catalogue: Precise chemo-kinematics in the extended solar vicinity
Friedrich Anders, Anna B. Queiroz, Cristina Chiappini +4
We describe the DR14 APOGEE-TGAS catalogue, a new SDSS value-added catalogue that provides precise astrophysical parameters, chemical abundances, astro-spectro-photometric distance…
Timing the Evolution of the Galactic Disk with NGC 6791: An Open Cluster with Peculiar High- Chemistry as seen by APOGEE
Sean T. Linden, Matthew Pryal, Christian R. Hayes +19
We utilize elemental-abundance information for Galactic red giant stars in five open clusters (NGC 7789, NGC 6819, M67, NGC 188, and NGC 6791) from the Apache Point Observatory Gal…
SDSS IV MaNGA - Rotation Velocity Lags in the Extraplanar Ionized Gas from MaNGA Observations of Edge-on Galaxies
D. Bizyaev, R. A. M. Walterbos, P. Yoachim +10
We present a study of the kinematics of the extraplanar ionized gas around several dozen galaxies observed by the Mapping of Nearby Galaxies at the Apache Point Observatory (MaNGA)…
Mapping the inner stellar halo of the Milky Way from 2MASS and SDSS-III/APOGEE survey
J. G. Fernández-Trincado, A. C. Robin, C. Reylé
The Besançon Galaxy model was used to compare the infrared colour distribution of synthetic stars with those from 2MASS observations taking the selection function of the data into…
Mapping optically variable quasars towards the galactic plane
J. G. Fernandez-Trincado, T. Verdugo, C. Reylé +13
We present preliminary results of the CIDA Equatorial Variability Survey (CEVS), looking for quasar (hereafter QSO) candidates near the Galactic plane. The CEVS contains photometri…
