Representing complex data using localized principal components with application to astronomical data
Jochen Einbeck, Ludger Evers, Coryn Bailer-Jones
Often the relation between the variables constituting a multivariate data space might be characterized by one or more of the terms: ``nonlinear'', ``branched'', ``disconnected'', `…
Dynamical Evolution of a Supernova Driven Turbulent Interstellar Medium
Dieter Breitschwerdt, Miguel A. de Avillez
It is shown that a number of key observations of the Galactic ISM can be understood, if it is treated as a highly compressible and turbulent medium energized predominantly by super…
Merger Dynamics of the Pair of Galaxy Clusters -- A399 and A401
Qirong Yuan, Pengfei Yan, Yanbin Yang +1
Convincing evidence of a past interaction between two rich clusters A399 and A401 was recently found by the X-ray imaging observations. In this paper we examine the structure and d…
Keynote Lecture: Galactic and Extragalactic Bubbles
D. Breitschwerdt, M. A. de Avillez, M. J. Freyberg
The observational and theoretical state of Galactic and extragalactic bubbles are reviewed. Observations of superbubbles are discussed, with some emphasis on nearby bubbles such as…
Reconstructing images of gravitational lenses with regularizing algorithms
E. Koptelova, E. Shimanovskaya, B. Artamonov +3
This note addresses possible applications of the Tikhonov regularization to image reconstruction of gravitational lens systems. Several modifications of the regularization algorith…
Polarization of photospheric lines from turbulent dynamo simulations
J. Sánchez Almeida, T. Emonet, F. Cattaneo
We employ the magnetic and velocity fields from turbulent dynamo simulations to synthesize the polarization of a typical photospheric line. The synthetic Stokes profiles have prope…
