A High Velocity Cloud Detected Towards M13
Résumé
We present HST-COS observations of the interstellar sight-line towards the M13 globular cluster. High velocity gas at V -120 km/s and intermediate velocity gas at V -65 km/s has been detected in many UV absorption lines. The HVC gas is probably associated with the Complex K IVC with a distance of 1.0 < z < 4.7 kpc. This would place the infalling HVC gas far closer than previous estimates of HV clouds surrounding our Galaxy.
