Leonardo da Vinci's view on turbulence is reproduced

To understand turbulence we need the intuitive perspective of art

The subject of Heisenberg’s doctoral dissertation, however, wasn’t quantum physics. It was harder than that. The 59-page calculation that he submitted to the faculty of the University of Munich in 1923 was titled “On the stability and turbulence of fluid flow.”

... with the sketches of wild water flows made by Leonardo da Vinci in the 15th century.

Galaxy Clusters from Planck (with Herschel)

http://herschel.cf.ac.uk/results/galaxy-clusters-planck

How Herschel changed the Universe !

Speaker : Dr. Chris Pearson (Herschel SPIRE Post-Operations Manager, RAL
Space, Rutherford Appleton Laboratory, UK.)
Date: 2015-02-11 

Abstract:
The European Space Agency’s Herschel Infrared Space Observatory was
launched in 2009 and completed an incredible 3 year mission making more
than 40,000 individual observations at far-infrared to sub-millimetre
wavelengths. At 3.5m, Herschel remains the largest mirror ever launched
into space and has produced images of exquisite detail and quality.
Herschel has revolutionised our understanding of the infrared Universe,
revealing new populations of galaxies and tracing back the history of
cosmic star-formation to the earliest epochs of the Universe. In this
talk, I will introduce the Herschel mission and its legacy and impact on
the study of galaxy evolution and cosmology.

SUZAKU OBSERVATIONS OF THE X-RAY BRIGHTEST FOSSIL GROUP ESO 3060170

Suzaku AO10 proposal: 2D Mapping of Abell2199

We have performed a Suzaku key project, "Distribution of Temperature and Entropy of Intracluster Medium of nearby clusters up to Virial Radius" in AO6 and observed the galaxy cluster Abell2199. This along with other pointings covers a large area reaching to the virial radius. We propose to complete this mapping by additional 10 pointings. This provides a wide, deep and complete X-ray view of a nearby relaxed cluster. This should be the highest quality cluster data set in the Suzaku archive. We measure the two-dimensional and large-scale properties of the ICM to understand thermal history of large-scale structure formation.We also compare the ICM distribution with our deep galaxy catalog and probe local and global galaxy-ICM interations.
