I am delighted to announce the publication of the following double special issue in Classical and Quantum Gravity:

Invited papers from Numerical Relativity and Data Analysis (NRDA) 2009,
Albert Einstein Institute, Potsdam, 6 – 9 July, 2009
Guest Editors: S Husa and B Krishnan

Invited papers from Microphysics In Computational Relativistic Astrophysics (MICRA) 2009,
Niels Bohr International Academy, Copenhagen, 24 – 28 August 2009
Guest Editors: C D Ott, C Pethick and L Rezzolla

The NRDA meeting was aimed at fostering closer interactions between simulations of gravitational wave sources and the ongoing searches for gravitational wave signals.

The MICRA meeting brought together researchers in numerical modeling and physics of matter at high densities, where general relativity plays a central role.

I take this opportunity to thank all of the authors, referees and guest editors who gave their time and expertise to create this excellent issue.

The special issue will be free for 6 months from date of publication. I invite you to read the articles on the new IOPscience service!

Yours sincerely,

Adam Day
