We present the first detection of HCO+ absorption in the Magellanic System. Using the ATCA, we observed nine extragalactic radio continuum sources behind the Magellanic System and detected HCO+ absorption toward one source located behind the leading edge of the Magellanic Bridge. The detection is located at an LSR velocity of v 214.0 0.4 km s = -1 , with an FWHM of v 4.5 1.0 km s D = -1 , and an optical depth of t (HCO ) 0.10 0.0 = 2 + . Although there is abundant neutral hydrogen...[Show more]
