Significance in gamma-ray astronomy - the Li & Ma problem in Bayesian statistics

- S. Gillessen, H. L. Harney
- Physics
- 24 November 2004

The significance of having detected an astrophysical gamma ray source is usually calculated by means of a formula derived by Li & Ma (1983, ApJ, 272, 317). We solve the same problem in terms of… Expand

Induced violation of time-reversal invariance in the regime of weakly overlapping resonances.

- B. Dietz, T. Friedrich, +5 authors H. Weidenmueller
- Physics, Medicine
- Physical review letters
- 9 February 2009

We measure the complex scattering amplitudes of a flat microwave cavity (a "chaotic billiard"). Time-reversal (T) invariance is partially broken by a magnetized ferrite placed within the cavity. We… Expand
