A directed search for gravitational waves from Scorpius X-1 with initial LIGO
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +891
We present results of a search for continuously-emitted gravitational radiation, directed at the brightest low-mass X-ray binary, Scorpius X-1. Our semi-coherent analysis covers 10…
Mapping the core mass function to the initial mass function
David Guszejnov, Philip F. Hopkins
It has been shown that fragmentation within self-gravitating, turbulent molecular clouds ("turbulent fragmentation") can naturally explain the observed properties of protostellar c…
Narrow-band search of continuous gravitational-wave signals from Crab and Vela pulsars in Virgo VSR4 data
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +894
In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In orde…
GIZMO: A New Class of Accurate, Mesh-Free Hydrodynamic Simulation Methods
Philip F. Hopkins
We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, SPH, and stationary (non-moving) grid methods. The new methods are designed to…
No More Active Galactic Nuclei in Clumpy Disks Than in Smooth Galaxies at z~2 in CANDELS / 3D-HST
Jonathan R. Trump, Guillermo Barro, Stephanie Juneau +23
We use CANDELS imaging, 3D-HST spectroscopy, and Chandra X-ray data to investigate if active galactic nuclei (AGNs) are preferentially fueled by violent disk instabilities funnelin…
Galactic r-process enrichment by neutron star mergers in cosmological simulations of a Milky Way-mass galaxy
Freeke van de Voort, Eliot Quataert, Philip F. Hopkins +2
We quantify the stellar abundances of neutron-rich r-process nuclei in cosmological zoom-in simulations of a Milky Way-mass galaxy from the Feedback In Realistic Environments proje…
