The Sixteenth Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra
Romina Ahumada, Carlos Allende Prieto, Andres Almeida +310
This paper documents the sixteenth data release (DR16) from the Sloan Digital Sky Surveys; the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of…
A Tip of the Red Giant Branch Distance to the Dark Matter Deficient Galaxy NGC1052-DF4 from Deep Hubble Space Telescope Data
Shany Danieli, Pieter van Dokkum, Roberto Abraham +3
Previous studies have shown that the large, diffuse galaxies NGC1052-DF2 and NGC1052-DF4 both have populations of unusually luminous globular clusters as well as a very low dark ma…
The low density and magnetization of a massive galaxy halo exposed by a fast radio burst
J. Xavier Prochaska, Jean-Pierre Macquart, Matthew McQuinn +16
Present-day galaxies are surrounded by cool and enriched halo gas extending to hundreds of kiloparsecs. This halo gas is thought to be the dominant reservoir of material available…
The CFHT Large Area U-band Deep Survey (CLAUDS)
Marcin Sawicki, Stephane Arnouts, Jiasheng Huang +37
The CFHT Large Area U-band Deep Survey (CLAUDS) uses data taken with the MegaCam mosaic imager on CFHT to produce images of 18.60 deg2 with median seeing of FWHM=0.92 arcsec and to…
The SLUGGS Survey: Measuring globular cluster ages using both photometry and spectroscopy
Christopher Usher, Jean P. Brodie, Duncan A. Forbes +4
Globular cluster ages provide both an important test of models of globular cluster formation and a powerful method to constrain the assembly history of galaxies. Unfortunately, mea…
IMF radial gradients in most massive early-type galaxies
F. La Barbera, A. Vazdekis, I. Ferreras +8
Using new long-slit spectroscopy obtained with X-Shooter at ESO-VLT, we study, for the first time, radial gradients of optical and Near-Infrared IMF-sensitive features in a represe…
Quenching as a Contest between Galaxy Halos and their Central Black Holes
Zhu Chen, S. M. Faber, David. C. Koo +27
Existing models of galaxy formation have not yet explained striking correlations between structure and star-formation activity in galaxies, notably the sloped and moving boundaries…
Dark matter and no dark matter: On the halo mass of NGC 1052
Duncan A. Forbes, Adebusola Alabi, Jean P. Brodie +1
The NGC 1052 group, and in particular the discovery of two ultra diffuse galaxies with very low internal velocity dispersions, has been the subject of much attention recently. Here…
Measuring the Orbital Parameters of Radial Velocity Systems in Mean Motion Resonance---a Case Study of HD 200964
M. M. Rosenthal, W. Jacobson-Galan, B. Nelson +8
The presence of mean motion resonances (MMRs) complicates analysis and fitting of planetary systems observed through the radial velocity (RV) technique. MMR can allow planets to re…
Elemental Abundances in M31: First Alpha and Iron Abundance Measurements in M31's Giant Stellar Stream
Karoline M. Gilbert, Evan N. Kirby, Ivanna Escala +3
We present the first measurements of [Fe/H] and [/Fe] abundances, obtained using spectral synthesis modeling, for red giant branch stars in M31's giant stellar stream. The spect…
Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper II: Applications of PCA-based stellar mass estimates
Zachary J. Pace, Christy Tremonti, Yanmei Chen +9
A galaxy's stellar mass is one of its most fundamental properties, but it remains challenging to measure reliably. With the advent of very large optical spectroscopic surveys, effi…
Resolved and Integrated Stellar Masses in the SDSS-IV/MaNGA Survey, Paper I: PCA spectral fitting & stellar mass-to-light ratio estimates
Zachary J. Pace, Christy Tremonti, Yanmei Chen +9
We present a method of fitting optical spectra of galaxies using a basis set of six vectors obtained from principal component analysis (PCA) of a library of synthetic spectra of 40…
Structural and Stellar Population Properties vs. Bulge Types in Sloan Digital Sky Survey Central Galaxies
Yifei Luo, S. M. Faber, Aldo Rodriguez-Puebla +12
This paper studies pseudo-bulges (P-bulges) and classical bulges (C-bulges) in Sloan Digital Sky Survey central galaxies using the new bulge indicator , which measures relati…
The CANDELS/SHARDS multi-wavelength catalog in GOODS-N: Photometry, Photometric Redshifts, Stellar Masses, Emission line fluxes and Star Formation Rates
Guillermo Barro, Pablo G. Perez-Gonzalez, Antonio Cava +52
We present a WFC3 F160W (-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts and…
Signatures of stellar accretion in MaNGA early-type galaxies
Grecco A. Oyarzun, Kevin Bundy, Kyle B. Westfall +10
The late assembly of massive galaxies is thought to be dominated by stellar accretion in their outskirts (beyond 2 effective radii Re) due to dry, minor galaxy mergers. We use obse…
Signatures of a planet-planet impacts phase in exoplanetary systems hosting giant planets
Renata Frelikh, Hyerin Jang, Ruth A. Murray-Clay +1
Exoplanetary systems host giant planets on substantially non-circular, close-in orbits. We propose that these eccentricities arise in a phase of giant impacts, analogous to the fin…
Spatially Resolved Stellar Kinematics of the Ultra-Diffuse Galaxy Dragonfly 44: II. Constraints on Fuzzy Dark Matter
Asher Wasserman, Pieter van Dokkum, Aaron J. Romanowsky +9
Given the absence of directly detected dark matter (DM) as weakly interacting massive particles, there is strong interest in the possibility that DM is an ultra-light scalar field,…
Hyper Wide Field Imaging of the Local Group Dwarf Irregular Galaxy IC 1613: An Extended Component of Metal-poor Stars
Ragadeepika Pucha, Jeffrey L. Carlin, Beth Willman +10
Stellar halos offer fossil evidence for hierarchical structure formation. Since halo assembly is predicted to be scale-free, stellar halos around low-mass galaxies constrain proper…
Spatially-resolved stellar kinematics of the ultra diffuse galaxy Dragonfly 44. I. Observations, kinematics, and cold dark matter halo fits
Pieter van Dokkum, Asher Wasserman, Shany Danieli +8
We present spatially-resolved stellar kinematics of the well-studied ultra diffuse galaxy (UDG) Dragonfly 44, as determined from 25.3 hrs of observations with the Keck Cosmic Web I…
Can intrinsic alignments of elongated low-mass galaxies be used to map the cosmic web at high redshift?
Viraj Pandya, Joel Primack, Peter Behroozi +13
Hubble Space Telescope observations show that low-mass () galaxies at high redshift () tend to be elongated (prolate) rather than disky (oblat…
