XMM-Newton Spectra of Intermediate-Mass Black Hole Candidates: Application of a Monte Carlo Simulated Model
NGC 5408 NGC 628
2014/12/24
We present a systematic spectral analysis of six ultraluminous X-ray sources (NGC 1313 X-1 and X-2, IC 342 X-1, Ho IX X-1, NGC 5408 X-1, and NGC 3628 X-1) observed with the XMM-Newton observatory. The...
Computing the Bayes Factor from a Markov chain Monte Carlo Simulation of the Posterior Distribution
Markov chain Bayes Factor
2014/12/22
Computation of the marginal likelihood from a simulated posterior distribution is central to Bayesian model selection but is computationally difficult. I argue that the marginal likelihood can be reli...
REAS3: Monte Carlo simulations of radio emission from cosmic ray air showers using an "end-point" formalism
REAS3 Monte Carlo simulations
2011/1/11
In recent years, the freely available Monte Carlo code REAS for modelling radio emission from cosmic ray air showers has evolved to include the full complexity of air shower physics. However, it turne...
Spectral Index as a Function of Mass Accretion Rate in Black Hole Sources. Monte-Carlo Simulations and an Analytical Description
black hole physics accretion disks radiation mechanisms
2010/11/16
We present herein a theoretical study of correlations between spectral indexes of X-ray emergent spectra and mass accretion rate (m˙ ) in black hole (BH) sources,which provide a definitive signature f...
Monte Carlo simulations of the Nickel K$\alpha$ fluorescent emission line in a toroidal geometry
galaxies active - line formation - radiation mechanism general - scattering - X-rays general
2010/11/12
We present new results from Monte Carlo calculations of the flux and equivalent width(EW) of the Ni K fluorescent emission line in the toroidal X-ray reprocessor model of Murphy & Yaqoob (2009, MNRAS...
General Relativistic Magnetohydrodynamic and Monte Carlo Modeling of Sagittarius A*
accretion disc black hole Galactic Center magnetohydrodynamics
2010/11/11
We present results of models of the physical space and parameters of the accretion disk of Sagittarius A*, as well as simulations of its emergent spectrum.This begins with HARM, a 2D general relativis...
The thesis deals with the first stage of planet formation, namely dust coagulation from
micron to millimeter sizes in circumstellar disks. For the first time, we collect and compile
the recent labor...
A Monte Carlo Approach to Evolution of the Far-Infrared Luminosity Function with BLAST
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We constrain the evolution of the rest-frame far-infrared (FIR) luminosity function out to z~3.5 by combining several pieces of complementary information provided by the deep Balloon-borne Large-Apert...
On the Modified Random Walk for Monte-Carlo Radiation Transfer
Instrumentation and Methods for Astrophysics
2010/12/22
Min et al. (2009) presented two complementary techniques that use the diffusion approximation to allow efficient Monte-Carlo radiation transfer in very optically thick regions: a modified random walk ...
