TiNy Titans: The Role of Dwarf-Dwarf Interactions in the Evolution of Low Mass Galaxies
S. Stierwalt, G. Besla, D. Patton +5
We introduce TiNy Titans (TNT), the first systematic study of star formation and the subsequent processing of the interstellar medium in interacting dwarf galaxies. Here we present…
A Focused, Hard X-ray Look at Arp 299 with NuSTAR
A. Ptak, A. Hornschemeier, A. Zezas +19
We report on simultaneous observations of the local starburst system Arp 299 with NuSTAR and Chandra, which provides the first resolved images of this galaxy up to energies of ~ 45…
Cosmological simulations of galaxy formation with cosmic rays
Munier Salem, Greg L. Bryan, Cameron Hummels
We investigate the dynamical impact of cosmic rays in cosmological simulations of galaxy formation using adaptive-mesh refinement simulations of a solar mass halo. In agr…
The Q/U Imaging Experiment: Polarization Measurements of Radio Sources at 43 and 95 GHz
QUIET Collaboration, K. M. Huffenberger, D. Araujo +24
We present polarization measurements of extragalactic radio sources observed during the Cosmic Microwave Background polarization survey of the Q/U Imaging Experiment (QUIET), opera…
Two Local Volume Dwarf Galaxies Discovered in 21 cm Emission: Pisces A and B
Erik J. Tollerud, Marla C. Geha, Jana Grcevich +2
We report the discovery of two dwarf galaxies, Pisces A and B, from a blind 21 cm HI search. These were the only two galaxies found via optical imaging and spectroscopy of 22 HI cl…
Uhlenbeck's Complaint
E. A. Spiegel
The passage from kinetic theory to fluid dynamics as discussed by Hilbert has perplexed Uhlenbeck. Herein, I try to smooth over the discord.
Dust in the Circumgalactic Medium of Low-Redshift Galaxies
J. E. G. Peek, Brice Ménard, Lia Corrales
Using spectroscopically selected galaxies from the Sloan Digital Sky Survey we present a detection of reddening due to dust in the circumgalactic medium of galaxies. We detect the…
The suppression of direct collapse black hole formation by soft X-ray irradiation
Kohei Inayoshi, Takamitsu L. Tanaka
The origin of supermassive black holes (SMBHs) in galactic nuclei is one of the major unsolved problems in astrophysics. One hypothesis is that they grew from >10^5 M_sun black hol…
The Formation of Massive, Compact Galaxies at z=2 in the Illustris Simulation
Sarah Wellons, Paul Torrey, Chung-Pei Ma +13
Massive, quiescent galaxies at high redshift have been found to be considerably more compact than galaxies of similar mass in the local universe. How these compact galaxies formed…
Modelling the supernova-driven ISM in different environments
A. Gatto, S. Walch, M. -M. Mac Low +11
We use hydrodynamical simulations in a periodic box to model the impact of supernova (SN) explosions on the multi-phase interstellar medium (ISM) for initial de…
Legacy ExtraGalactic UV Survey (LEGUS) with The Hubble Space Telescope. I. Survey Description
D. Calzetti, J. C. Lee, E. Sabbi +46
The Legacy ExtraGalactic UV Survey (LEGUS) is a Cycle 21 Treasury program on the Hubble Space Telescope, aimed at the investigation of star formation and its relation with galactic…
The Void Galaxy Survey: Galaxy Evolution and Gas Accretion in Voids
Kathryn Kreckel, Jacqueline H. van Gorkom, Burcu Beygu +4
Voids represent a unique environment for the study of galaxy evolution, as the lower density environment is expected to result in shorter merger histories and slower evolution of g…
Reconstructing the Accretion History of the Galactic Stellar Halo from Chemical Abundance Ratio Distributions
Duane M. Lee, Kathryn V. Johnston, Bodhisattva Sen +1
Observational studies of halo stars during the last two decades have placed some limits on the quantity and nature of accreted dwarf galaxy contributions to the Milky Way stellar h…
Kinetic energy from supernova feedback in high-resolution galaxy simulations
Christine M. Simpson, Greg L. Bryan, Cameron Hummels +1
We describe a new method for adding a prescribed amount of kinetic energy to simulated gas modeled on a cartesian grid by directly altering grid cells' mass and velocity in a distr…
Tidal Stream Morphology as an Indicator of Dark Matter Halo Geometry: the Case of Palomar 5
Sarah Pearson, Andreas H. W. Küpper, Kathryn V. Johnston +1
This paper presents an example where the morphology of a single stellar stream can be used to rule out a specific galactic potential form without the need for velocity information.…
The stellar accretion origin of stellar population gradients in massive galaxies at large radii
Michaela Hirschmann, Thorsten Naab, Jeremiah P. Ostriker +5
We investigate the evolution of stellar population gradients from to in massive galaxies at large radii () using ten cosmological zoom simulation…
Under the sword of Damocles: plausible regeneration of dark matter cusps at the smallest galactic scales
Chervin F. P. Laporte, Jorge Peñarrubia
We run controlled N-body experiments to study the evolution of the dark matter (DM) halo profiles of dwarf galaxies driven by the accretion of DM substructures. Our initial conditi…
The effect of primordial mass segregation on the size scale of globular clusters
Hosein Haghi, Seyed Mohammad Hoseini-Rad, Akram Hasani Zonoozi +1
We use direct -body calculations to investigate the impact of primordial mass segregation on the size scale and mass-loss rate of star clusters in a galactic tidal field. We run…
The Zurich Environmental Study (ZENS) of Galaxies in Groups along the Cosmic Web. V. Properties and Frequency of Merging Satellites and Centrals in Different Environments
