Evidence of Fanning in the Ophiuchus Stream
B. Sesar, A. M. Price-Whelan, J. G. Cohen +11
The Ophiuchus stellar stream presents a dynamical puzzle: its old stellar populations ( Gyr) cannot be reconciled with (1) its orbit in a simple model for the Milky Way po…
The Sizes of Globular Clusters as Tracers of Galactic Halo Potentials
Akram Hasani Zonoozi, Malihe Rabiee, Hosein Haghi +1
We present -body simulations of globular clusters, exploring the effect of different galactic potentials on cluster sizes, . For various galactocentric distances, , we…
Matching dust emission structures and magnetic field in high-latitude cloud L1642: comparing Herschel and Planck maps
J. Malinen, L. Montier, J. Montillaud +7
The nearby cloud L1642 is one of only two known very high latitude (|b| > 30 deg) clouds actively forming stars. It is a rare example of star formation in isolated conditions, and…
Role of Cosmic Rays in the Circumgalactic Medium
Munier Salem, Greg L. Bryan, Lauren Corlies
We explore the impact of cosmic rays (CRs) on cosmological adaptive-mesh refinement simulations of a forming 10^12 Msolar halo, focusing on the circumgalactic medium (CGM), and its…
AGN feedback and star formation in ETGs: negative and positive feedback
L. Ciotti, J. P. Ostriker, A. Negri +3
AGN feedback from supermassive black holes (SMBHs) at the center of early type galaxies is commonly invoked as the explanation for the quenching of star formation in these systems.…
The stellar mass assembly of galaxies in the Illustris simulation: growth by mergers and the spatial distribution of accreted stars
Vicente Rodriguez-Gomez, Annalisa Pillepich, Laura V. Sales +9
We use the Illustris simulation to study the relative contributions of in situ star formation and stellar accretion to the build-up of galaxies over an unprecedentedly wide range o…
Early Science with the Large Millimeter Telescope: COOL BUDHIES I - a pilot study of molecular and atomic gas at z~0.2
Ryan Cybulski, Min S. Yun, Neal Erickson +20
An understanding of the mass build-up in galaxies over time necessitates tracing the evolution of cold gas (molecular and atomic) in galaxies. To that end, we have conducted a pilo…
First Results from COPSS: The CO Power Spectrum Survey
Garrett K. Keating, Geoffrey C. Bower, Daniel P. Marrone +11
We present constraints on the abundance of carbon-monoxide in the early Universe from the CO Power Spectrum Survey (COPSS). We utilize a data set collected between 2005 and 2008 us…
A Statistical Method to Search for Recoiling Supermassive Black Holes in Active Galactic Nuclei
Peter Raffai, Zoltan Haiman, Zsolt Frei
We propose an observational test for gravitationally recoiling supermassive black holes (BHs) in active galactic nuclei, based on a correlation between the velocities of BHs relati…
A NuSTAR Survey of Nearby Ultraluminous Infrared Galaxies
Stacy H. Teng, Jane R. Rigby, Daniel Stern +17
We present a NuSTAR, Chandra, and XMM--Newton survey of nine of the nearest ultraluminous infrared galaxies (ULIRGs). The unprecedented sensitivity of NuSTAR at energies above 10 k…
Evidence for the Thermal Sunyaev-Zel'dovich Effect Associated with Quasar Feedback
Devin Crichton, Megan B. Gralla, Kirsten Hall +20
Using a radio-quiet subsample of the Sloan Digital Sky Survey spectroscopic quasar catalogue, spanning redshifts 0.5-3.5, we derive the mean millimetre and far-infrared quasar spec…
Globular Cluster Streams as Galactic High-Precision Scales
A. H. W. Küpper, E. Balbinot, A. Bonaca +4
Tidal streams of globular clusters are ideal tracers of the Galactic gravitational potential. Compared to the few known, complex and diffuse dwarf-galaxy streams, they are kinemati…
Tidal debris morphology and the orbits of satellite galaxies
David Hendel, Kathryn V. Johnston
How do galaxies move relative to one another? While we can examine the motion of dark matter subhalos around their hosts in simulations of structure formation, determining the orbi…
A Large Systematic Search for Close Supermassive Binary and Rapidly Recoiling Black Holes - II. Continued Spectroscopic Monitoring and Optical Flux Variability
Jessie C. Runnoe, Michael Eracleous, Gavin Mathes +6
We present new spectroscopic observations that are part of our continuing monitoring campaign of 88 quasars at z<0.7 whose broad H lines are offset from their systemic redshifts…
The NANOGrav Nine-year Data Set: Astrometric Measurements of 37 Millisecond Pulsars
Allison M. Matthews, David J. Nice, Emmanuel Fonseca +18
Using the nine-year radio-pulsar timing data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), collected at Arecibo Observatory and the Green Ba…
Launching cosmic-ray-driven outflows from the magnetized interstellar medium
Philipp Girichidis, Thorsten Naab, Stefanie Walch +10
We present a hydrodynamical simulation of the turbulent, magnetized, supernova (SN)-driven interstellar medium (ISM) in a stratified box that dynamically couples the injection and…
Warm Gas in and Around Simulated Galaxy Clusters as Probed by Absorption Lines
Andrew Emerick, Greg Bryan, Mary E. Putman
Understanding gas flows into and out of the most massive dark matter structures in our Universe, galaxy clusters, is fundamental to understanding their evolution. Gas in clusters i…
Young Stellar Objects in the Gould Belt
Michael M. Dunham, Lori E. Allen, Neal J. Evans +14
We present the full catalog of Young Stellar Objects (YSOs) identified in the 18 molecular clouds surveyed by the Spitzer Space Telescope "cores to disks" (c2d) and "Gould Belt" (G…

Modeling Galactic Conformity with the Color-Halo Age Relation in the Illustris Simulation
Aaron D. Bray, Annalisa Pillepich, Laura V. Sales +9
Comparisons between observational surveys and galaxy formation models find that the mass of dark matter haloes can largely explain galaxies' stellar mass. However, it remains uncer…
