Computation of transient electromagnetic fields due to switching in high voltage substations [PDF]

open access: yes, 2010
Switching operations of circuit breakers and disconnect switches radiate transient electromagnetic fields within high-voltage substations. The generated fields may interfere and disrupt normal operations of electronic equipment.

Stacked Search for Gravitational Waves from the 2006 SGR 1900+14 Storm [PDF]

open access: yes, 2009
We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with the 2006 March 29 SGR 1900+14 storm. A new search method is used, "stacking'' the GW data around the times of individual soft-gamma bursts in the storm ...
