Independent components in spectroscopic analysis of complex mixtures
Yulia B. Monakhova, Sergey A. Astakhov, Alexander Kraskov +1
We applied two methods of "blind" spectral decomposition (MILCA and SNICA) to quantitative and qualitative analysis of UV absorption spectra of several non-trivial mixture types. B…
Production of trans-Neptunian binaries through chaos-assisted capture
Ernestine A. Lee, Sergey A. Astakhov, David Farrelly
The recent discovery of binary objects in the Kuiper-belt opens an invaluable window into past and present conditions in the trans-Neptunian part of the Solar System. For example,…
Monte Carlo Algorithm for Least Dependent Non-Negative Mixture Decomposition
Sergey A. Astakhov, Harald Stögbauer, Alexander Kraskov +1
We propose a simulated annealing algorithm (called SNICA for "stochastic non-negative independent component analysis") for blind decomposition of linear mixtures of non-negative so…
Formation of Kuiper-belt binaries through multiple chaotic scattering encounters with low-mass intruders
Sergey A. Astakhov, Ernestine A. Lee, David Farrelly
The discovery that many trans-neptunian objects exist in pairs, or binaries, is proving invaluable for shedding light on the formation, evolution and structure of the outer Solar s…
Spectral Mixture Decomposition by Least Dependent Component Analysis
Sergey A. Astakhov, Harald Stögbauer, Alexander Kraskov +1
A recently proposed mutual information based algorithm for decomposing data into least dependent components (MILCA) is applied to spectral analysis, namely to blind recovery of con…
Capture and escape in the elliptic restricted three-body problem
Sergey A. Astakhov, David Farrelly
Several families of irregular moons orbit the giant planets. These moons are thought to have been captured into planetocentric orbits after straying into a region in which the plan…
