Galaxy Formation Subgrid Models

Multiple models are available in SWIFT. The ‘Basic’ model can be use as an empty canvas to be copied to create additional models.

Available models:

• EAGLE model
  • Gas entropy floors
  • Chemical tracers
  • Gas cooling: Wiersma+2009a
  • Particle tracers
  • Star formation: Schaye+2008 modified for EAGLE
  • Stellar enrichment: Wiersma+2009b
  • Supernova feedback: Dalla Vecchia+2012 & Schaye+2015
  • Supernova and enrichment parameters in the EAGLE-Ref model
  • Black-hole creation
  • Black-hole accretion
  • Black-hole repositioning
  • AGN feedback
• Quick Lyman-alpha (QLA) model
  • Gas entropy floor
  • Gas cooling: Wiersma+2009a with fixed primordial metallicity
  • Star formation
• GEAR model
  • Pressure Floor
  • Cooling: Grackle
  • Star formation
  • Chemistry
  • Feedback
• Basic model (others)
  • Cooling: Analytic models
