Satellite accretion in action: a tidally disrupting dwarf spheroidal around the nearby spiral galaxy NGC 253
Aaron J. Romanowsky, D. Martinez-Delgado, Nicolas F. Martin +7
We report the discovery of NGC 253-dw2, a dwarf spheroidal (dSph) galaxy candidate undergoing tidal disruption around a nearby spiral galaxy, NGC 253 in the Sculptor group: the fir…
The SLUGGS Survey: stellar kinematics, kinemetry and trends at large radii in 25 early-type galaxies
Caroline Foster, Nicola Pastorello, Joel Roediger +9
Due to longer dynamical timescales, the outskirts of early-type galaxies retain the footprint of their formation and assembly. Under the popular two-phase galaxy formation scenario…
Kinematics and Angular Momentum in Early Type Galaxy Halos
Jean P. Brodie, Aaron Romanowsky, the SLUGGS team
We use the kinematics of discrete tracers, primarily globular clusters (GCs) and planetary nebulae (PNe), along with measurements of the integrated starlight to explore the assembl…
The Bright Symbiotic Mira EF Aquilae
Bruce Margon, J. Xavier Prochaska, Nicolas Tejos +1
An incidental spectrum of the poorly studied long period variable EF Aquilae shows [O III] emission indicative of a symbiotic star. Strong GALEX detections in the UV reinforce this…
A tidally disrupting dwarf galaxy in the halo of NGC 253
Elisa Toloba, David Sand, Kristine Spekkens +7
We report the discovery of Scl-MM-Dw2, a new dwarf galaxy at a projected separation of 50 kpc from NGC 253, as part of the PISCeS (Panoramic Imaging Survey of Centaurus and S…
Infrared color selection of massive galaxies at z > 3
T. Wang, D. Elbaz, C. Schreiber +29
We introduce a new color-selection technique to identify high-redshift, massive galaxies that are systematically missed by Lyman-break selection. The new selection is based on the…
The AIMSS Project III: The Stellar Populations of Compact Stellar Systems
Joachim Janz, Mark A. Norris, Duncan A. Forbes +11
In recent years, a growing zoo of compact stellar systems (CSSs) have been found whose physical properties (mass, size, velocity dispersion) place them between classical globular c…
The SLUGGS survey: chromo-dynamical modelling of the lenticular galaxy NGC 1023
Arianna Cortesi, Ana L. Chies-Santos, Vincenzo Pota +12
Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper,…
Breaking the Curve with CANDELS: A Bayesian Approach to Reveal the Non-Universality of the Dust-Attenuation Law at High Redshift
Brett Salmon, Casey Papovich, James Long +13
Dust attenuation affects nearly all observational aspects of galaxy evolution, yet very little is known about the form of the dust-attenuation law in the distant Universe. Here, we…
The extended halo of Centaurus A: uncovering satellites, streams, and substructures
D. Crnojević, D. J. Sand, K. Spekkens +7
We present the widest-field resolved stellar map to date of the closest ( Mpc) massive elliptical galaxy NGC 5128 (Centaurus A; Cen A), extending out to a projected galac…
A Deep Search For Faint Galaxies Associated With Very Low-redshift C IV Absorbers: III. The Mass- and Environment-dependent Circumgalactic Medium
Joseph N. Burchett, Todd M. Tripp, Rongmon Bordoloi +6
Using Hubble Space Telescope Cosmic Origins Spectrograph observations of 89 QSO sightlines through the Sloan Digital Sky Survey footprint, we study the relationships between C IV a…
The Lick-Carnegie Exoplanet Survey: HD32963 -- A New Jupiter Analog Orbiting a Sun-like Star
Dominick Rowan, Stefano Meschiari, Gregory Laughlin +10
We present a set of 109 new, high-precision Keck/HIRES radial velocity (RV) observations for the solar-type star HD 32963. Our dataset reveals a candidate planetary signal with a p…
Evidence for the rapid formation of low mass early-type galaxies in dense environments
Yiqing Liu, Eric W. Peng, John Blakeslee +6
We explore the environmental dependence of star formation timescales in low mass galaxies using the [/Fe] abundance ratio as an evolutionary clock. We present integrated [/Fe…
UBVRIz Light Curves of 51 Type II Supernovae
Lluís Galbany, Mario Hamuy, Mark M. Phillips +34
We present a compilation of UBV RIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986 to 2003: the Cerro Tololo Supernova Sur…
Satellite Quenching and Galactic Conformity at 0.3 < z < 2.5
Lalitwadee Kawinwanichakij, Ryan F. Quadri, Casey Papovich +21
We measure the evolution of the quiescent fraction and quenching efficiency of satellites around star-forming and quiescent central galaxies with stellar mass $\log(M_{\mathrm{cen}…
The physical properties of z>2 Lyman limit systems: new constraints for feedback and accretion models
Michele Fumagalli, John M. O'Meara, J. Xavier Prochaska
We study the physical properties of a homogeneous sample of 157 optically-thick absorption line systems at redshifts ~1.8-4.4, selected from a high-dispersion spectroscopic survey…
Panchromatic Hubble Andromeda Treasury XII. Mapping Stellar Metallicity Distributions in M31
Dylan Gregersen, Anil C. Seth, Benjamin F. Williams +14
We present a study of spatial variations in the metallicity of old red giant branch stars in the Andromeda galaxy. Photometric metallicity estimates are derived by interpolating is…
