Gaia-assisted discovery of a detached low-ionisation BAL quasar with very large ejection velocities
J. P. U. Fynbo, P. Møller, K. E. Heintz +10
We report on the discovery of a peculiar Broad Absorption Line (BAL) quasar identified in our Gaia-assisted survey of red quasars. The systemic redshift of this quasar was difficul…
The Distribution of Ultra-Diffuse and Ultra-Compact Galaxies in the Frontier Fields
Steven R. Janssens, Roberto Abraham, Jean Brodie +2
Large low surface brightness galaxies have recently been found to be abundant in nearby galaxy clusters. In this paper, we investigate these ultra-diffuse galaxies (UDGs) in the si…

A hidden friend for the galactic center black hole, Sgr A*
Smadar Naoz, Clifford M. Will, Enrico Ramirez-Ruiz +3
The hierarchical nature of galaxy formation suggests that a supermassive black hole binary could exist in our galactic center. We propose a new approach to constraining the possibl…
Large Scale Structures in the CANDELS Fields: The Role of the Environment in Star Formation Activity
Nima Chartab, Bahram Mobasher, Behnam Darvish +14
We present a robust method, weighted von Mises kernel density estimation, along with boundary correction to reconstruct the underlying number density field of galaxies. We apply th…
The Activation of Galactic Nuclei and Their Accretion Rates are Linked to the Star Formation Rates and Bulge-types of Their Host Galaxies
Hassen M. Yesuf, S. M. Faber, David C. Koo +3
We use bulge-type classifications of 809 representative SDSS galaxies by Gadotti (2009) to classify a large sample of galaxies into real bulges (classical or elliptical) and pseudo…
Elemental Abundances in M31: The Kinematics and Chemical Evolution of Dwarf Spheroidal Satellite Galaxies
Evan N. Kirby, Karoline M. Gilbert, Ivanna Escala +4
We present deep spectroscopy from Keck/DEIMOS of Andromeda I, III, V, VII, and X, all of which are dwarf spheroidal satellites of M31. The sample includes 256 spectroscopic members…
Momentum Injection by Clustered Supernovae: Testing Subgrid Feedback Prescriptions
Eric S. Gentry, Piero Madau, Mark R. Krumholz
Using a 1D Lagrangian code specifically designed to assess the impact of multiple, time-resolved supernovae (SNe) from a single star cluster on the surrounding medium, we test thre…
Globular clusters in the stellar stream surrounding the Milky Way analog NGC 5907
Adebusola B. Alabi, Duncan A. Forbes, Aaron J. Romanowsky +1
We study the globular clusters (GCs) in the spiral galaxy NGC~5907 well-known for its spectacular stellar stream -- to better understand its origin. Using wide-field Subaru/Suprime…
A mass threshold for galactic gas discs by spin flips
Avishai Dekel, Omri Ginzburg, Fangzhou Jiang +4
We predict, analytically and by simulations, that gas discs tend to survive only in haloes above a threshold mass (stellar mass )…
The role of galaxies and AGN in reionising the IGM -- III : IGM-galaxy cross-correlations at z~6 from 8 quasar fields with DEIMOS and MUSE
Romain A. Meyer, Koki Kakiichi, Sarah E. I. Bosman +6
We present improved results of the measurement of the correlation between galaxies and the intergalactic medium (IGM) transmission at the end of reionisation. We have gathered a sa…
Milky Way Satellite Census. I. The Observational Selection Function for Milky Way Satellites in DES Y3 and Pan-STARRS DR1
A. Drlica-Wagner, K. Bechtol, S. Mau +55
We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and PS1…
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…
How Accurately Can We Detect the Splashback Radius of Dark Matter Halos and its Correlation With Accretion Rate?
Enia Xhakaj, Benedikt Diemer, Alexie Leauthaud +5
The splashback radius () of dark matter halos has recently been detected using weak gravitational lensing and cross-correlations with galaxies. However, different metho…
Are galactic star formation and quenching governed by local, global or environmental phenomena?
Asa F. L. Bluck, Roberto Maiolino, Sebastian Sanchez +5
We present an analysis of star formation and quenching in the SDSS-IV MaNGA-DR15, utilising over 5 million spaxels from 3500 local galaxies. We estimate star formation rate s…
The cold circumgalactic environment of MAMMOTH-I: dynamically cold gas in the core of an Enormous Ly-alpha Nebula
Bjorn Emonts, Zheng Cai, Xavier Prochaska +2
The MAMMOTH-I Nebula at redshift 2.3 is one of the largest known Ly-alpha nebulae in the Universe, spanning ~440 kpc. Enormous Ly-alpha nebulae like MAMMOTH-I typically trace the d…
Probing the galaxy-halo connection with total satellite luminosity
Jeremy L. Tinker, Junzhi Cao, Mehmet Alpaslan +3
We demonstrate how the total luminosity in satellite galaxies is a powerful probe of dark matter halos around central galaxies. The method cross-correlates central galaxies in spec…
