ABSTRACT: OGLE-IV, in operation since March 2010, is one of the largest sky surveys worldwide, regularly monitoring about one billion objects and collecting over 30 TB of raw data per year with the new generation 32-chip CCD mosaic camera...

ABSTRACT: Star cluster ecology is the field of research where stellar evolution, gravitational dynamics, hydrodynamcs and the background potential dynamics of the parent galaxy interact to a complex non-linear evolution of self gravitating...

The Bar and Spiral Structure Legacy (BeSSeL) Survey is an NRAO Key Science Project that has been awarded 5000 hours of VLBA observing time from 2010 to 2015. Results from the first year's observations will be presented. A major goal is to determine...

ABSTRACT: The last few years have seen a tremendous increase of observational data regarding the properties of extrasolar planets. High precision radial velocity and transit observations have yielded large datasets which are important to improve our...

ABSTRACT: The simple paradigm of a galaxy cluster as isolated, smooth and spherical leads to many useful results, both about clusters themselves and when using clusters for cosmological parameters and galaxy evolution. A high resolution large...

ABSTRACT: I will summarize and discuss the body of evidence which has accumulated in favor of dark matter in the form of approximately 10 GeV particles. This evidence includes the spectrum and angular distribution of gamma rays from the Galactic...

ABSTRACT: The presence of liquid water has been hypothesized as an important ingredient for planet habitability. A sub-Neptune mass planet with a liquid water ocean below a hydrogen-rich envelope is an intriguing prospect. If the planet transits...

ABSTRACT: The galaxy population appears to be composed of infinitely complex different types and properties at first sight. However, when large samples of galaxies are studied, it appears that the vast majority of galaxies just follow simple scaling...
