Star Formation Mitosis: The Effects of Particle Splitting on the Star Formation Outcome
Shivan Khullar, Michael Y. Grudić, Christopher D. Matzner +3
Particle splitting can increase the dynamic range in Lagrangian astrophysical simulations by several orders of magnitude. However, such methods can introduce numerical noise that m…
FORGE'd in the Early Universe: The Effect of Protostellar Outflows on Pop III Accretion
Yasmine J. Meziani, Philip F. Hopkins, Michael Y. Grudić +3
We present a cosmological zoom-in radiation magneto-hydrodynamic (RMHD) simulation, using FORGE'd in FIRE, that follows the formation, growth, and evolution of a single metal-free…
Playing with FIRE: A Galactic Feedback-Halting Experiment Challenges Star Formation Rate Theories
Shivan Khullar, Christopher D. Matzner, Norman Murray +4
Stellar feedback influences the star formation rate (SFR) and the interstellar medium of galaxies in ways that are difficult to quantify numerically, because feedback is an essenti…
The density structure of supersonic self-gravitating turbulence
Shivan Khullar, Christoph Federrath, Mark R. Krumholz +1
We conduct numerical experiments to determine the density probability distribution function (PDF) produced in supersonic, isothermal, self-gravitating turbulence of the sort that i…
The Single-Cloud Star Formation Relation
Riwaj Pokhrel, Robert A. Gutermuth, Mark R. Krumholz +10
One of the most important and well-established empirical results in astronomy is the Kennicutt-Schmidt (KS) relation between the density of interstellar gas and the rate at which t…
Probing the high-z IGM with the hyperfine transition of He
Shivan Khullar, Qingbo Ma, Philipp Busch +3
The hyperfine transition of He at 3.5cm has been thought as a probe of the high-z IGM since it offers a unique insight into the evolution of the helium component of the gas…
Determining Star Formation Thresholds from Observations
Shivan Khullar, Mark R. Krumholz, Christoph Federrath +1
Most gas in giant molecular clouds is relatively low-density and forms star inefficiently, converting only a small fraction of its mass to stars per dynamical time. However, star f…
