Effelsberg Observations of Excited-State (6.0 GHz) OH in Supernova Remnants and W3(OH)

Although masers in the 1720 MHz transition of OH are detected toward many supernova remnants (SNRs), no other OH transition is seen as a maser in SNRs. We present a search for masers at 6049 MHz, which has recently been predicted to produce masers by pure collisional excitation at conditions similar...
