TWEAKING GENERAL RELATIVITY: MOND RELATIVISTIC GRAVITY THEORY AS A SUBSTITUTE FOR DARK MATTER

The success of the standard concordance cosmological model in predicting the primordial abundances of the light elements, and modeling the power spectrum of fluctuations of the cosmic microwave background have suggested to many that its ingredients are all one needs to understand galaxies and galaxy systems. However, a number of known problems with this expectation may signal the failure of standard gravity theory already on galaxy scales. An alternative nonrelativistic gravity theory - AQUAL, suggested by the phenomenological MOND paradigm, does rather well for ...

Instrumentation and Analysis part 2

In a first part, we will present the basics of tracing and what the major issues are. We will present some of the main tracing environments and try to compare them. We will focus on extrae and present some mechanisms that allow to increase scalability. We will also describe some of the analysis capabilities motivating such mechanisms and how to use them. In particular, we will present a couple of recent developments with clustering and processing sampled data ("folding"). We will illustrate the resulting analysis with paraver. ...
