SBSS 0953+549 also known asSBS 0953+549 andQSO J0957+5440, is aquasar located in the constellation ofUrsa Major. With aredshift of 2.58, the object is located approximately 10.8 billionlight-years away fromEarth.[1] It is classified as a broadabsorption-line quasar (BAL QSO) by theSloan Digital Sky Survey.[2] It was first studied in the 1980s as part of the Second Byurakan Survey.[3]
SBS 0953+549 contains both strong and weak absorption systems. It has powerfulultravioletemission lines and an energic nuclear module.[4] A further investigation have shown it possesses an emission line profile similar to that of aP Cygni-type, featuringLyman α and β line pairs.[3][5]
