SPICY 30021: an embedded bona fide FUor with a mid-infrared precursor
Zhen Guo, Calum Morris, Vitor Fermiano +37
Unstable mass accretion in young stellar objects (YSOs) often leads to observable outbursts, which play a key role in stellar mass assembly during pre-main-sequence evolution. The…
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

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…
Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
Beatriz Barbuy, José G. Fernández-Trincado, Morgan S. Camargo +9
Phosphorus enhanced (P-rich; [P/Fe] > 0.8) giants have been found among mildly metal-poor fiels stars, but in only one star in a globular cluster (GC), M4 (NGC 6121). Also, in a sa…
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…
A view of the H-band light-element chemical patterns in Globular Clusters under the AGB self-enrichment scenario
F. Dell'Agli, D. A. García-Hernández, P. Ventura +7
We discuss the self-enrichment scenario by AGB stars for the formation of multiple populations in globular clusters (GCs) by analyzing data set of giant stars observed in 9 Galacti…
Abundance anomalies in red giants with possible extragalactic origins unveiled by APOGEE-2
