Post-Newtonian simulations of super-massive black hole binaries in galactic nuclei
(Wiley-VCH Verlag Berlin: Astronomische Nachrichten, 2008-12)
We present some preliminary results from recent numerical simulations that model the evolution of super-massive black
hole (SMBH) binaries in galactic nuclei. Including the post-Newtonian terms for the binary system and ...
An Instability in triaxial stellar systems
(Wiley InterScience: Astronomische Nachrichten, 2008-12)
The radial-orbit instability is a collective phenomenon that has heretofore only been observed in spherical systems. We
find that this instability occurs also in triaxial systems, as we checked by performing extensive ...
The Production of self-organized carbon connections between Ag nanoparticles using atmospheric microplasma synthesis
(Elsevier, 2008-10-10)
The formation of long self-organized carbon connections (where the length is much greater
than the diameter) between Ag nanoparticles on a Si(100) surface in atmospheric pressure
Ar + CH4 microplasmas is demonstrated. A ...
Integrating the determinants of suction feeding performance in centrarchid fishes
(Company of Biologists, 2008-10-07)
When suction-feeding vertebrates expand their buccal cavity to draw water into their mouth, they also exert a hydrodynamic force
on their prey. This force is key to strike success, directly countering forces exerted by ...
A Hybrid N-Body Code incorporating algorithmic regularization and Post-Newtonian forces
(Wiley InterScience: Monthly Notices of the Royal Astronomical Society, 2008-07-24)
We describe a novel N-body code designed for simulations of the central regions of
galaxies containing massive black holes. The code incorporates Mikkola’s “algorithmic”
chain regularization scheme including post-Newtonian ...
Two more candidate AM Canum Venaticorum (AM CVn) Binaries from the Sloan Digital Sky Survey
(American Astronomical Society - The Astronomical Journal, 2008-06)
AM CVn systems are a select group of ultracompact binaries with the shortest
orbital periods of any known binary subclass; mass-transfer is likely from a
low-mass (partially-)degenerate secondary onto a white dwarf ...
First-Year spectroscopy for the SDSS-II Supernova Survey
(American Astronomical Society - The Astronomical Journal, 2008-05)
This paper presents spectroscopy of supernovae discovered in the first season
of the Sloan Digital Sky Survey-II Supernova Survey. This program searches
for and measures multi-band light curves of supernovae in the ...
The rotating wind of the quasar PG 1700+518
(Nature Publishing Group, 2008-02-27)
It is now widely accepted that most galaxies undergo an active phase, during which a
central super-massive black hole generates vast radiant luminosities through the
gravitational accretion of gas1,2. Winds launched from ...
The Sloan Digital Sky Survey-II Supernova Survey: search Algorithm and follow-up observations
(American Astronomical Society - The Astronomical Journal, 2008-01)
The Sloan Digital Sky Survey-II Supernova Survey has identified a large number
of new transient sources in a 300 deg2 region along the celestial equator during
its first two seasons of a three-season campaign. Multi-band ...
Towards a spectral technique for determining material geometry around evolved stars: Application to HD 179821
(Wiley-Blackwell, 2008)
HD 179821 is an evolved star of unknown progenitor mass range (either post-
Asymptotic Giant Branch or post-Red Supergiant) exhibiting a double peaked spectral
energy distribution (SED) with a sharp rise from ∼ 8−20 μm. ...
