Tidal stellar disruptions by massive black hole pairs: II. Decaying binaries
Xian Chen, Alberto Sesana, Piero Madau +1
Tidal stellar disruptions have traditionally been discussed as a probe of the single, massive black holes (MBHs) that are dormant in the nuclei of galaxies. In Chen et al. (2009),…
Radio and Gamma-Ray Constraints on the Emission Geometry and Birthplace of PSR J2043+2740
A. Noutsos, A. A. Abdo, M. Ackermann +146
We report on the first year of Fermi gamma-ray observations of pulsed high-energy emission from the old PSR J2043+2740. The study of the gamma-ray efficiency of such old pulsars gi…
Multi-Element Abundance Measurements from Medium-Resolution Spectra. IV. Alpha Element Distributions in Milky Way Dwarf Satellite Galaxies
Evan N. Kirby, Judith G. Cohen, Graeme H. Smith +3
We derive the star formation histories of eight dwarf spheroidal (dSph) Milky Way satellite galaxies from their alpha element abundance patterns. Nearly 3000 stars from our previou…
Multi-Element Abundance Measurements from Medium-Resolution Spectra. II. Catalog of Stars in Milky Way Dwarf Satellite Galaxies
Evan N. Kirby, Puragra Guhathakurta, Joshua D. Simon +7
We present a catalog of Fe, Mg, Si, Ca, and Ti abundances for 2961 red giant stars that are likely members of eight dwarf satellite galaxies of the Milky Way (MW): Sculptor, Fornax…
Multi-Element Abundance Measurements from Medium-Resolution Spectra. III. Metallicity Distributions of Milky Way Dwarf Satellite Galaxies
Evan N. Kirby, Gustavo A. Lanfranchi, Joshua D. Simon +2
We present metallicity distribution functions (MDFs) for the central regions of eight dwarf satellite galaxies of the Milky Way: Fornax, Leo I and II, Sculptor, Sextans, Draco, Can…
The Mass Distribution and Assembly of the Milky Way from the Properties of the Magellanic Clouds
Michael T. Busha, Philip J. Marshall, Risa H. Wechsler +2
We present a new measurement of the mass of the Milky Way (MW) based on observed properties of its largest satellite galaxies, the Magellanic Clouds (MCs), and an assumed prior of…
Quantifying Kinematic Substructure in the Milky Way's Stellar Halo
Xiang-Xiang Xue, Hans-Walter Rix, Brian Yanny +13
We present and analyze the positions, distances, and radial velocities for over 4000 blue horizontal-branch (BHB) stars in the Milky Way's halo, drawn from SDSS DR8. We search for…
Binaries migrating in a gaseous disk: Where are the Galactic center binaries?
C. Baruteau, J. Cuadra, D. N. C. Lin
The massive stars in the Galactic center inner arcsecond share analogous properties with the so-called Hot Jupiters. Most of these young stars have highly eccentric orbits, and wer…
A model of Mira's cometary head/tail entering the Local Bubble
A. Esquivel, A. C. Raga, J. Canto +4
We model the cometary structure around Mira as the interaction of an AGB wind from Mira A, and a streaming environment. Our simulations introduce the following new element: we assu…
Detection of 16 Gamma-Ray Pulsars Through Blind Frequency Searches Using the Fermi LAT
LAT Collaboration
Pulsars are rapidly-rotating, highly-magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until r…
Light-Element Abundance Variations at Low Metallicity: the Globular Cluster NGC 5466
Matthew Shetrone, Sarah L. Martell, Rachel Wilkerson +4
We present low-resolution (R~850) spectra for 67 asymptotic giant branch (AGB), horizontal branch and red giant branch (RGB) stars in the low-metallicity globular cluster NGC 5466,…
SEGUE-2 Limits on Metal-Rich Old-Population Hypervelocity Stars In the Galactic Halo
Juna A. Kollmeier, Andrew Gould, Constance Rockosi +7
We present new limits on the ejection of metal-rich old-population hypervelocity stars from the Galactic center (GC) as probed by the SEGUE-2 survey. Our limits are a factor of 3-1…
Recoiling Massive Black Holes in Gas-Rich Galaxy Mergers
Javiera Guedes, Piero Madau, Lucio Mayer +1
The asymmetric emission of gravitational waves produced during the coalescence of a massive black hole (MBH) binary imparts a velocity "kick" to the system that can displace the ho…
The SEGUE Stellar Parameter Pipeline. IV. Validation with an Extended Sample of Galactic Globular and Open Clusters
Jason P Smolinski, Young Sun Lee, Timothy C Beers +7
Spectroscopic and photometric data for likely member stars of five Galactic globular clusters (M3, M53, M71, M92, and NGC 5053) and three open clusters (M35, NGC 2158, and NGC 6791…
AEGIS: A Multi-wavelength Study of Spitzer Power-law Galaxies
S. Q. Park, P. Barmby, S. P. Willner +8
This paper analyzes a sample of 489 Spitzer/IRAC sources in the Extended Groth Strip whose spectral energy distributions fit a red power law from 3.6 to 8.0 \micron. The median for…
On the Evolution of the Velocity-Mass-Size Relations of Disk-Dominated Galaxies over the Past 10 Billion Years
Aaron A. Dutton, Frank C. van den Bosch, S. M. Faber +10
We study the evolution of the scaling relations between maximum circular velocity, stellar mass and optical half-light radius of star-forming disk-dominated galaxies in the context…
Systematic Effects in Extracting a "Gamma-Ray Haze" from Spatial Templates
Tim Linden, Stefano Profumo
Recent claims of a gamma-ray excess in the diffuse galactic emission detected by the Fermi Large Area Telescope with a morphology similar to the WMAP haze were based on the assumpt…
The Morphology of the Galactic Dark Matter Synchrotron Emission with Self-Consistent Cosmic Ray Diffusion Models
Tim Linden, Stefano Profumo, Brandon Anderson
A generic prediction in the paradigm of weakly interacting dark matter is the production of relativistic particles from dark matter pair-annihilation in regions of high dark matter…
A population of gamma-ray emitting globular clusters seen with the Fermi Large Area Telescope
The Fermi LAT collaboration
Globular clusters with their large populations of millisecond pulsars (MSPs) are believed to be potential emitters of high-energy gamma-ray emission. Our goal is to constrain the m…
Radiation Feedback, Fragmentation, and the Environmental Dependence of the Initial Mass Function
Mark R. Krumholz, Andrew J. Cunningham, Richard I. Klein +1
The fragmentation of star-forming interstellar clouds, and the resulting stellar initial mass function (IMF), is strongly affected by the temperature structure of the collapsing ga…
The Long-term Evolution of the Galactic Disk Traced by Dissolving Star Clusters
Joss Bland-Hawthorn, Mark Krumholz, Ken Freeman
The Galactic disk retains a vast amount of information about how it came to be, and how it evolved over cosmic time. However, we know very little about the secular processes associ…
Fermi Large Area Telescope observations of PSR J1836+5925
The Fermi LAT Collaboration
The discovery of the gamma-ray pulsar PSR J1836+5925, powering the formerly unidentified EGRET source 3EG J1835+5918, was one of the early accomplishments of the Fermi Large Area T…
