How galaxies are influenced in the Universe - Mehmet Alpaslan (SETI Talk.
Δημοσιεύτηκε στις 25 Νοε 2016
When
viewed at the largest scales, the distribution of galaxies in the
Universe resembles a complex, tangled web: an interconnected network of
filaments of galaxies that surround vast, empty voids. Simulations and
theory have established that filaments – the largest, most densely
populated structures in the Universe - have formed in the billions of
years after the Big Bang, and serve as conduits for transporting gas
into galaxies, which they then turn into stars. Thanks to advances in
telescope instrumentation the current generation of galaxy surveys is
finally able to observe the night sky in sufficient detail as to
accurately map the Cosmic Web for the first time, and begin to
understand the role it plays in influencing the evolutionary fate of
galaxy.
In this talk, Dr. Alpaslan will review advances in mapping
out the filamentary network of the Universe using data from the Galaxy
And Mass Assembly (GAMA) survey, as well as discuss some recent advances
in understanding how the galaxies that live in dense filament differ
from those that exist alone in isolated voids.
