Modeling Supernovae Feedback as a Galactic Fountain
Stellar feedback can drive a galactic fountain by pushing out gas that later falls back in.
When Do Stars Form? Simulating Dynamic Star Formation Efficiencies in Giant Molecular Clouds
Observations of Giant Molecular Clouds (GMCs) yield large scatters in star formation efficiencies. Simulations in this work show that much of this scatter may stem from the fact we observe GMCs at different evolutionary stages driven by stellar feedback.
How to Un-squash a Galaxy
Does our galaxy look like an Advil, a NyQuil, or just a simple sphere? The simulations studied in today’s paper may have the answer.
Can an Orphaned Exomoon Help Solve the Mystery of Tabby’s Star?
Simulations by astronomers at Columbia University suggest an evaporating exomoon could be behind the mysterious dimming behaviour of KIC 8462852.
New Cosmological Detectives: Using FRBs to Constrain the Diffuse Gas Fraction
With an ideal dataset of many localized FRBs, how can the diffuse gas fraction in the IGM be constrained?
Explaining Ancient Stellar Populations
Why do some dwarf galaxies exhibit such old stellar populations? Perhaps simulations of reionization including radiative transfer can help to explain this peculiar trait.
