Abstract:
The Universe is dying. All across the cosmos for the last 10 billion
years galaxies have been continuously killed, and we still don't know
why. Today the Universe is littered with dead galaxies, and their
distribution is correlated with location (environment). This suggests
that location is one of the prime suspects in this galactic
whodunit. However, previous observations and techniques have
restricted us to only measuring galaxy environments in the nearby
Universe, inhibiting our ability to identify when, where and why they
are killed. In addition, galaxy location might not be the only suspect
in town. Monsters are hiding at the centres of the most massive
galaxies, ready to lead to their untimely demise. In this talk I will
discuss various programs using large multi-wavelength surveys, such as
GAMA and DEVILS, to explore the smoking gun factors that have led to
the death of galaxies over the last 10billion years.
