The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Marvin: A Toolkit for Streamlined Access and Visualization of the SDSS-IV MaNGA Data Set
Brian Cherinka, Brett H. Andrews, José Sánchez-Gallego +11
The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, one of three core programs of the fourth-generation Sloan Digital Sky Survey (SDSS-IV), is producing a massi…
Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle
B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58
The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…
SDSS-IV MaStar -- A Large and Comprehensive Empirical Stellar Spectral Library: First Release
Renbin Yan, Yanping Chen, Daniel Lazarz +45
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength range of 3,622-10,354A…
Formation of ultra-diffuse galaxies in the field and in galaxy groups
Fangzhou Jiang, Avishai Dekel, Jonathan Freundlich +4
We study ultra-diffuse galaxies (UDGs) in zoom in cosmological simulations, seeking the origin of UDGs in the field versus galaxy groups. We find that while field UDGs arise from d…
Weak Lensing Reveals a Tight Connection Between Dark Matter Halo Mass and the Distribution of Stellar Mass in Massive Galaxies
Song Huang, Alexie Leauthaud, Andrew Hearin +9
Using deep images from the Hyper Suprime-Cam (HSC) survey and taking advantage of its unprecedented weak lensing capabilities, we reveal a remarkably tight connection between the s…
The MAGNUM survey: different gas properties in the outflowing and disk components in nearby active galaxies with MUSE
M. Mingozzi, G. Cresci, G. Venturi +17
We investigated the interstellar medium properties of the disc and outflowing gas in the central regions of nine nearby Seyfert galaxies, all characterised by prominent outflows. T…
Constraining Sub-Parsec Binary Supermassive Black Holes in Quasars with Multi-Epoch Spectroscopy. III. Candidates from Continued Radial Velocity Tests
Hengxiao Guo, Xin Liu, Yue Shen +3
Quasars whose broad emission lines show temporal, bulk radial velocity (RV) shifts have been proposed as candidate sub-parsec (sub-pc), binary supermassive black holes (BSBHs). We…
New Formation Models for the Kepler-36 System
Peter Bodenheimer, David J. Stevenson, Jack J. Lissauer +1
Formation of the planets in the Kepler-36 system is modeled by detailed numerical simulations according to the core-nucleated accretion scenario. The standard model is updated to i…
Simulating the M-R Relation from APF follow up of TESS targets: Survey design and strategies for overcoming mass biases
Jennifer Burt, Bradford P. Holden, Angie Wolfgang +1
We present simulations of multi-year RV follow up campaigns of the {\it TESS} small exoplanet yield on the Automated Planet Finder telescope, using four different schemes to sample…
Mirach's Goblin: Discovery of a dwarf spheroidal galaxy behind the Andromeda galaxy
David Martinez-Delgado, Eva K. Grebel, Behnam Javanmardi +9
It is of broad interest for galaxy formation theory to carry out a full inventory of the numbers and properties of dwarf galaxies in the Local Volume, both satellites and isolated…
Project AMIGA: Distance and Metallicity Gradients Along Andromeda's Giant Southern Stream from the Red Clump
Roger E. Cohen, Jason S. Kalirai, Karoline M. Gilbert +7
The Giant Southern Stream (GSS) of M31, a keystone signature of a major accretion event, yields crucial constraints on M31 formation and evolution models. Currently, our understand…
Revisiting the X-ray - Mass scaling relations of Early-type Galaxies with the Mass of their Globular Cluster Systems as a Proxy for the Total Galaxy Mass
Dong-Woo Kim, Nicholas James, Giuseppina Fabbiano +2
Using globular cluster (GC) kinematics and photometry data, we calibrate the scaling relation between the total galaxy mass (M_TOT including dark matter) and total globular cluster…
The WAGGS project - II. The reliability of the calcium triplet as a metallicity indicator in integrated stellar light
Christopher Usher, Thomas Beckwith, Sabine Bellstedt +12
Using data from the WiFeS Atlas of Galactic Globular cluster Spectra we study the behaviour of the calcium triplet (CaT), a popular metallicity indicator in extragalactic stellar p…
IQ-Collaboratory 1.1: the Star-Forming Sequence of Simulated Central Galaxies
ChangHoon Hahn, Tjitske K. Starkenburg, Ena Choi +12
A tightly correlated star formation rate-stellar mass relation of star forming galaxies, or star-forming sequence (SFS), is a key feature in galaxy property-space that is predicted…
Dissecting cold gas in a high-redshift galaxy using a lensed background quasar
J. -K. Krogager, P. Noterdaeme, J. M. O'Meara +9
We present a study of cold gas absorption from a damped Lyman- absorber (DLA) at redshift towards two lensed images of the quasar J144254.78+405535.5 at reds…
A direct test of density wave theory in a grand-design spiral galaxy
Thomas Peterken, Michael Merrifield, Alfonso Aragon-Salamanca +5
The exact nature of the arms of spiral galaxies is still an open question. It has been widely assumed that spiral arms in galaxies with two distinct symmetrical arms are the produc…
