Classifying structures in the ISM with Support Vector Machines: the G16.05-0.57 supernova remnant
Classifying structures Support Vector Machines supernova remnant
2011/10/20
We apply Support Vector Machines -- a machine learning algorithm -- to the task of classifying structures in the Interstellar Medium. As a case study, we present a position-position velocity data cube...
Pasta Structures of Quark-Hadron Phase Transition in Proto-Neutron Stars
Pasta Structures Quark-Hadron Phase Transition
2011/1/11
We study the quark-hadron mixed phase in proto-neutron stars with the finite-size effects. In the calculations of pasta structures appeared in the mixed phase, the Gibbs conditions require the pressur...
Large Scale Structures in Kinetic Gravity Braiding Model
Large Scale Structures Kinetic Gravity Braiding Model
2010/11/12
We study cosmological consequences of a kinetic braiding model, which is proposed as an alternative to the dark energy model. The kinetic braiding model we study is characterised by a parameter n, whi...
Hierarchical Stellar Structures in the Local Group Dwarf Galaxy NGC 6822
Galaxy Astrophysics (astro-ph.GA) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present a comprehensive study of the star cluster population and the hierarchical structure in the clustering of blue stars with ages <~ 500 Myr in the Local Group dwarf irregular galaxy NGC 6822. ...
The evolution of stellar structures in dwarf galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present a study of the variation of spatial structure of stellar populations within dwarf galaxies as a function of the population age. We use deep Hubble Space Telescope/Advanced Camera for Survey...
Local causal structures, Hadamard states and the principle of local covariance in quantum field theory
quantum field theory local covariance
2010/3/18
In the framework of the algebraic formulation, we discuss and analyse some new features of the local structure of a real scalar quantum field theory in a strongly causal spacetime. In particular we us...
