Abstract (from CDS):

We report the first extragalactic detection of chloronium (H2Cl+) in the z=0.89 absorber in front of the lensed blazar PKS1830-211. The ion is detected through its 111-000 line along two independent lines of sight toward the North-East and South-West images of the blazar. The relative abundance of H2Cl+ is significantly higher (by a factor ∼7) in the NE line of sight, which has a lower H2/H fraction, indicating that H2Cl+ preferably traces the diffuse gas component. From the ratio of the H235Cl+ and H237Cl+ absorptions toward the SW image, we measure a 35Cl/37Cl isotopic ratio of 3.1–0.2+0.3 at z=0.89, similar to that observed in the Galaxy and the solar system.
