Web8 jul. 2016 · The LBL AP Librae has been detected in the TeV gamma-ray range, which is unexpected for this kind of blazar. The broad-band SED cannot be explained by a one-zone model, and especially fails in the TeV domain. An extended jet has been detected on arcsec scales both in radio and X-ray frequencies. The spectral index of the X-ray band … WebThe ground-based detectors LIGO, Virgo and GEO 600 (see [2–5] for recent status reports) are rapidly improving in sensitivity. The search of data from the last science run (LIGO S5, Virgo VSR1) of the initial versions of these detectors is still ongoing (see [6, 7] for upper limits on rates of low-mass binary mergers from the first part of the run).
