DESCRIPTION:Speakers: Will Roper (Oxford)\n\nUnderstanding how galaxies fo
 rm and evolve requires increasingly sophisticated simulations\, but with g
 reater physical realism comes a substantially higher cost of entry. Fortun
 ately\, high-quality science doesn't always have to mean paying this price
 . Sometimes\, being smarter about how we spend our computational resources
  (i.e. thinking like a cheapskate) can get us just as far\, or even furthe
 r!In this talk\, I'll explore two complementary approaches to getting more
  astrophysical "bang for your buck". The first is cosmological zoom simula
 tions\, where concentrating computational resources on only the regions of
  the Universe we care about dramatically reduces the cost of achieving our
  scientific goals. I'll introduce the concept of zoom simulations\, showca
 se some of the science they have enabled\, and discuss the technical chall
 enges I've encountered in developing and optimising these simulations.Prod
 ucing a simulation is only half the battle\, though. To understand what si
 mulations predict for real observations\, we need to leave the world of th
 eoretical outputs and "forward model" into the observational world. A proc
 ess rife with uncertainty and computational cost of its own. This is where
  Synthesizer comes in: an open-source framework for efficiently generating
  synthetic observables\, with performance and flexibility at its foundatio
 ns. I'll introduce the philosophy behind its development\, demonstrate som
 e of its capabilities\, and highlight the science it has enabled so far.Ul
 timately\, being a computational cheapskate isn't just about doing the sam
 e science for less. It's about making more ambitious science possible with
  the resources we already have\, pushing the boundaries of what we thought
  we could achieve.\n\nhttps://conference.astro.dur.ac.uk/event/15/
