DOIAbstract
The Galactic Center ridge has been observed extensively in the past by both GeV and TeV gamma-ray instrumentsrevealing a wealth of structure, including a diffuse component and the point sources G0.9+0.1 (a compositesupernova remnant) and Sgr A*(believed to be associated with the supermassive black hole located at the center of our Galaxy). Previous very high energy (VHE) gamma-ray observations with the H.E.S.S. experiment have also detected an extended TeV gamma-ray component along the Galactic plane in the > 300 GeV gamma-ray regime. Here we report on observations of the Galactic Center ridge from 2010 to 2014 by the VERITAS telescope array in the > 2 TeV energy range. From these observations we (1) provide improved measurements of the dif...
