The large-scale kinematics of young stars in the Milky Way disc: first results from SDSS-V
Eleonora Zari, Jaime Villaseñor, Marina Kounkel +17
We present a first large-scale kinematic map of 50,000 young OB stars ( K), based on BOSS spectroscopy from the Milky Way Mapper OB program in the on…
Towards Understanding the Milky Way's Typicality: Assessing the Chemodynamics of M31's Bulge & Bar, Thick & Thin Discs
Benjamin J. Gibson, Gail Zasowski, Anil Seth +6
We describe a novel framework to model galaxy spectra with two cospatial stellar populations, such as may represent a bulge & bar or thick & thin disc, and apply it to APOGEE spect…
SDSS IV MaNGA: The impact of the acquisition of gas with opposite angular momentum on the evolution of galaxies
Minje Beom, René A. M. Walterbos, Dmitry Bizyaev
A gaseous counter-rotating galaxy is a galaxy containing a gas component with opposite angular momentum to the main stellar disk. The counter-rotating gas provides direct evidence…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: A Kinematically Variable Broad-Line Region and Consequences for Masses of Luminous Quasars
Logan B. Fries, Jonathan R. Trump, Keith Horne +27
We present a velocity-resolved reverberation mapping analysis of the hypervariable quasar RM160 (SDSS J141041.25+531849.0) at z = 0.359 with 153 spectroscopic epochs of data repres…
Galaxies with Biconical Ionized Structure in MaNGA - I. Sample Selection and Driven Mechanisms
Zhi-Jie Zhou, Yan-Mei Chen, Run-Quan Guan +3
Based on the integral field unit (IFU) data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we develop a new method to select galaxies with biconical ioniz…
The SDSS-V Local Volume Mapper (LVM): Scientific Motivation and Project Overview
Niv Drory, Guillermo A. Blanc, Kathryn Kreckel +48
We present the Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM). The LVM is an integral-field spectroscopic survey of the Milky Way, Magellanic Clouds, and of a sample…
