Panel A / Chapter 2
Extremes of the Universe
Enlarged panel 24 January 2007


Science Questions
How did the Universe begin? What is dark matter and dark energy? Can we observe strong gravity in action? How do supernovae and gamma-ray bursts work? How do black hole accretion, jets and outflows operate? What do we learn about the Universe from energetic radiation and particles?
Science Vision for European Astronomy in the Next 20 Years

Broadest range of the panels: Standard physics in exotic settings But also the universe as a laboratory for new physics

Notes
More detailed specifications (wavelength ranges, depth and areas of surveys, spatial, temporal and spectral resolution, ....) in document Time scales of the different projects very different. Mix of space and ground Need to address role of current facilities. Eg. future dedicated `medium-size' facilities (eg 8-10 m class telescopes). Closing any facilities?

Needs more iterations among the panel members. List and motivations will evolve over the next few weeks Constructive input from community is welcome!
