Exploring Changing-look Active Galactic Nuclei with the Sloan Digital Sky Survey V: First Year Results
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32
"Changing-look" active galactic nuclei (CL-AGNs) challenge our basic ideas about the physics of accretion flows and circumnuclear gas around supermassive black holes. Using first-y…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
Stellar Properties for a Comprehensive Collection of Star Forming Regions in the SDSS APOGEE-2 Survey
Carlos G. Román-Zúñiga, Marina Kounkel, Jesús Hernández +25
The Sloan Digital Sky Survey IV (SDSS-IV) APOGEE-2 primary science goal was to observe red giant stars throughout the Galaxy to study its dynamics, morphology, and chemical evoluti…
SDSS-IV MaNGA: the chemical co-evolution of gas and stars in spiral galaxies
Michael J. Greener, Alfonso Aragón-Salamanca, Michael Merrifield +7
We investigate archaeologically how the metallicity in both stellar and gaseous components of spiral galaxies of differing masses evolve with time, using data from the SDSS-IV MaNG…
Is Terzan 5 the remnant of a building block of the Galactic bulge? Evidence from APOGEE
Dominic J. Taylor, Andrew C. Mason, Ricardo P. Schiavon +16
It has been proposed that the globular cluster-like system Terzan 5 is the surviving remnant of a primordial building block of the Milky Way bulge, mainly due to the age/metallicit…
The Open Cluster Chemical Abundances and Mapping Survey: VII. APOGEE DR17 [C/N]-Age Calibration
Taylor Spoo, Jamie Tayar, Peter M. Frinchaboy +11
Large scale surveys open the possibility to investigate Galactic evolution both chemically and kinematically, however, reliable stellar ages remain a major challenge. Detailed chem…
