Charting the Unseen: Using Advanced Tools to Map Dark Matter with Galaxy Surveys
Have you ever wondered about the mysterious invisible substance that makes up a significant part of our universe? Dark matter, as astronomers call it, is an enigmatic entity that exerts gravitational pull but does not emit, absorb, or reflect light. Despite its elusive nature, scientists have been striving to unravel its secrets by utilizing advanced tools and techniques, such as galaxy surveys.
Galaxy surveys serve as powerful maps that provide valuable insights into the distribution and behavior of dark matter. By observing the effects of dark matter on visible objects like galaxies, astronomers can infer its presence and create detailed maps of its structure on a large scale.
One groundbreaking tool used in these surveys is gravitational lensing. Imagine looking through a warped mirror that distorts the image of objects behind it. Similarly, the gravity of dark matter acts as a cosmic lens, bending and magnifying the light from distant galaxies. By studying these distortions, scientists can trace the hidden fingerprints left by dark matter.
Another technique employed in mapping dark matter is redshift surveys.
