The Exoplanet Orbit Database
Jason T Wright, Onsi Fakhouri, Geoffrey W. Marcy +8
We present a database of well determined orbital parameters of exoplanets. This database comprises spectroscopic orbital elements measured for 427 planets orbiting 363 stars from r…
The Merger Rates and Mass Assembly Histories of Dark Matter Haloes in the Two Millennium Simulations
Onsi Fakhouri, Chung-Pei Ma, Michael Boylan-Kolchin
We construct merger trees of dark matter haloes and quantify their merger rates and mass growth rates using the joint dataset from the Millennium and Millennium-II simulations. The…
The SAURON project - XV. Modes of star formation in early-type galaxies and the evolution of the red sequence
K. L. Shapiro, J. Falcon-Barroso, G. van de Ven +15
We combine SAURON integral field data of a representative sample of local early-type, red sequence galaxies with Spitzer/IRAC imaging in order to investigate the presence of trace…
Dark Matter Halo Growth II: Diffuse Accretion and its Environmental Dependence
Onsi Fakhouri, Chung-Pei Ma
Dark matter haloes in Lambda CDM simulations grow by mergers with other haloes as well as accretion of "diffuse" non-halo material. We quantify the mass growth rates via these two…
Mass Accretion Rates and Histories of Dark Matter Haloes
James McBride, Onsi Fakhouri, Chung-Pei Ma
We use the extensive catalog of dark matter haloes from the Millennium simulation to investigate the statistics of the mass accretion histories (MAHs) and accretion rates of ~500,0…
Environmental Dependence of Dark Matter Halo Growth I: Halo Merger Rates
Onsi Fakhouri, Chung-Pei Ma
In an earlier paper we quantified the mean merger rate of dark matter haloes as a function of redshift z, descendant halo mass M0, and progenitor halo mass ratio xi using the Mille…
How to Grow a Healthy Merger Tree
Jun Zhang, Onsi Fakhouri, Chung-Pei Ma
We investigate seven Monte Carlo algorithms -- four old and three new -- for constructing merger histories of dark matter halos using the extended Press-Schechter (EPS) formalism b…
Conditional Mass Functions and Merger Rates of Dark Matter Halos in the Ellipsoidal Collapse Model
Jun Zhang, Chung-Pei Ma, Onsi Fakhouri
Analytic models based on spherical and ellipsoidal gravitational collapse have been used to derive the mass functions of dark matter halos and their progenitors (the conditional ma…
The Nearly Universal Merger Rate of Dark Matter Haloes in Lambda-CDM Cosmology
Onsi Fakhouri, Chung-Pei Ma
We construct merger trees from the largest database of dark matter haloes to date provided by the Millennium simulation to quantify the merger rates of haloes over a broad range of…
