Search for coincidences with astrophysical transients in Pierre Auger Observatory data

Conferencia; 31th International Cosmic Ray Conference; 2009

We analyse extensive air shower datacollected by the Pierre Auger Observatory to searchfor coincidences between the arrival directions ofultra-high energy cosmic rays and the positions ofgamma-ray bursts. We also analyse the trigger ratedata from individual surface detector stations tosearch for an increase of the average trigger rateover the entire surface detector array in correlationwith gamma-ray bursts.
