Researchers At The Australian National University (ANU) Have Found Another Explanation For The Mysterious Gamma Ray Signal From The Center Of The Milky Way Galaxy It Is Reported That The Signal Has Long Been Known As A Sign Of Dark Matter. Gamma Ray Is The Electromagnetic Radiation Form With The Shortest Wavelength And The Highest Energy.
Associate Professor Roland Crocker, Co-author Of The Study, Pointed Out That This Special Gamma Ray Signal - Known As The Galactic Center Surplus - May Actually Come From A Specific Type Of Fast Rotating Neutron Star, That Is, The Super Dense Stellar Debris Of Some Stars With A Much Larger Mass Than Our Sun.
Galactic Center Excess Is An Unexpected Concentration Of Gamma Rays From The Center Of Our Galaxy, Which Has Long Puzzled Astronomers.
Associate Professor Crocker Said: "Our Work Does Not Raise Any Doubts About The Existence Of This Signal, But Provides Another Potential Source. It Is Based On Millisecond Pulsars - Neutron Stars That Rotate Very Fast - About 100 Times Per Second. Scientists Have Previously Detected Gamma Ray Emissions From Single Millisecond Pulsars Near The Solar System, So We Know That These Objects Will Emit Gamma Rays. Our Model Shows That The Synthesis From The Whole Group Of Stars There Are About 100000 Launches, Which Will Produce A Signal Exactly Consistent With The Excess At The Center Of The Milky Way Galaxy. "
The Discovery May Mean That Scientists Must Rethink Where They Are Looking For Clues About Dark Matter.
”The Nature Of Dark Matter Is Completely Unknown, So Any Potential Clue Will Get A Lot Of Excitement. But Our Results Point To Another Important Source Of Gamma Ray Production, "Crocker Said." For Example, The Gamma Ray Signal From Andromeda, The Large Galaxy Closest To Our Own Galaxy, May Be Mainly Caused By Millisecond Pulsars. "
