Time-Frequency Analysis of Superorbital Modulation of X-ray Binary SMC X-1 by Hilbert-Huang Transform
Time-Frequency Analysis Superorbital Modulation X-ray Binary SMC X-1 Hilbert-Huang Transform
2011/10/21
The high-mass X-ray binary (HMXB) SMC X-1 exhibits a superorbital modulation with a dramatically varying period ranging between ~40 d and ~60 d. This research studies the time-frequency properties of ...
The Australia Telescope 20GHz (AT20G) Survey: analysis of the extragalactic source sample
The Australia Telescope 20GHz (AT20G) Survey the extragalactic source sample
2011/1/13
The Australia Telescope 20 GHz (AT20G) survey is a blind survey of the whole Southern sky at 20 GHz with follow-up observations at 4.8, 8.6, and 20 GHz carried out with the Australia Telescope Compact...
The Doppler Shadow of WASP-3b: A tomographic analysis of Rossiter-McLaughlin observations
Earth and Planetary Astrophysics (astro-ph.EP)
2011/1/6
Hot-Jupiter planets must form at large separations from their host stars where the temperatures are cool enough for their cores to condense. They then migrate inwards to their current observed orbital...
f(T) gravity mimicking dynamical dark energy. Background and perturbation analysis
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc) High Energy Physics - Theory (hep-th)
2010/12/28
We investigate f(T) cosmology in both the background, as well as in the perturbation level, and we present the general formalism for reconstructing the equivalent one-parameter family of f(T) models f...
Needatool: A Needlet Analysis Tool for Cosmological Data Processing
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
We introduce NeedATool (Needlet Analysis Tool), a software for data analysis based on needlets, a wavelet rendition which is powerful for the analysis of fields defined on a sphere. Needlets have been...
A SIMPLE, APPROXIMATE METHOD FOR ANALYSIS OF KERR-NEWMAN BLACK HOLE DYNAMICS AND THERMODYNAMICS
Black hole physics Kerr-Newman black hole
2010/10/29
In this work we present a simple approximate method for analysis of the basic dynamical and thermodynamical characteristics of Kerr-Newman black hole. Instead of the complete dynamics of the black hol...
