Ionization fronts and their interaction with density fluctuations: implications for reionization
Ilian T. Iliev, Paul R. Shapiro, Evan Scannapieco +4
The propagation of cosmological ionization fronts (I-fronts) during reionization is strongly influenced by small-scale structure. Here we summarize our recent attemps to understand…
The interaction of a jet-like pulse with a wind from a stellar companion
A. Riera, A. C. Raga, J. Alcolea
We present numerical simulations of the interaction between a collimated, bipolar ``pulse'' ejected from a star and a continuous wind ejected from a stellar companion. We explore t…
Minihalo photoevaporation during cosmic reionization: evaporation times and photon consumption rates
Ilian T. Iliev, Paul R. Shapiro, Alejandro C. Raga
The weak, R-type ionization fronts (I-fronts) which swept across the intergalactic medium (IGM) during the reionization of the universe often found their paths blocked by cosmologi…
Hydrodynamical interaction between an accretion flow and a stellar wind
S. Mendoza, J. Canto, A. Raga
Molecular clouds in the interstellar medium suffer gravitational instabilities that lead to the formation of one or multiple stars. A recently formed star inside a cold cloud commu…
A model for the cross section of a turbulent, radiative jet or wake
J. Canto, A. C. Raga, A. Riera
We present an analytical model for the cross section of a turbulent, radiative jet or wake. This model is appropriate for modeling HH jets, or "wakes" left behind by "astrophysical…
Relation between source and temperature fluctuations in photoionized nebulae
Luc Binette, Pierre Ferruit, Wolfgang Steffen +1
The magnitude of the temperature fluctuations (t^2) required to explain the observed inconsistencies between metallicities inferred from recombination lines and from forbidden line…
