Analytical and Numerical Studies of the Non-uniformity induced Type II Asymmetric Cap Shock Mach Reflection in Over-expanded Supersonic Jets
Justin Kin Jun Hew, Rod W. Boswell, Christoph Federrath +2
A combined analytical and numerical study is conducted to investigate the asymmetric cap-shock non-uniform Mach Reflection (csMR) phenomenon outside of an over-expanded supersonic…
Outflows Driven by Direct and Reprocessed Radiation Pressure in Massive Star Clusters
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz
We use three-dimensional radiation hydrodynamic (RHD) simulations to study the formation of massive star clusters under the combined effects of direct ultraviolet (UV) and dust-rep…
Growth or Decay -- I: universality of the turbulent dynamo saturation
James R. Beattie, Christoph Federrath, Neco Kriel +2
The turbulent small-scale dynamo (SSD) is likely to be responsible for the magnetisation of the interstellar medium (ISM) that we observe in the Universe today. The SSD efficiently…
The role of the turbulence driving mode for the Initial Mass Function
Sajay Sunny Mathew, Christoph Federrath, Amit Seta
Turbulence is a critical ingredient for star formation, yet its role for the initial mass function (IMF) is not fully understood. Here we perform magnetohydrodynamical (MHD) simula…
Multiphase turbulence in galactic halos: effect of the driving
Rajsekhar Mohapatra, Christoph Federrath, Prateek Sharma
Supernova explosions, active galactic nuclei jets, galaxy--galaxy interactions and cluster mergers can drive turbulence in the circumgalactic medium (CGM) and in the intracluster m…
Infrared Radiation Feedback Does Not Regulate Star Cluster Formation
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz
We present 3D radiation-hydrodynamical (RHD) simulations of star cluster formation and evolution in massive, self-gravitating clouds, whose dust columns are optically thick to infr…
Rotation measure structure functions with higher-order stencils as a probe of small-scale magnetic fluctuations and its application to the Small and Large Magellanic Clouds
Amit Seta, Christoph Federrath, Jack D. Livingston +1
Magnetic fields and turbulence are important components of the interstellar medium (ISM) of star-forming galaxies. It is challenging to measure the properties of the small-scale IS…
Environmental variation of the low-mass IMF
Tabassum S Tanvir, Mark R Krumholz, Christoph Federrath
We use a series of magnetohydrodynamic simulations including both radiative and protostellar outflow feedback to study the environmental variation of the initial mass function. The…
Turbulence Generation by Shock Interaction with a Highly Non-Uniform Medium
Seth Davidovits, Christoph Federrath, Romain Teyssier +3
An initially planar shock wave propagating into a medium of non-uniform density will be perturbed, leading to the generation of post-shock velocity perturbations. Using numerical s…
The driving mode of shock-driven turbulence
Saee Dhawalikar, Christoph Federrath, Seth Davidovits +4
Turbulence in the interstellar medium (ISM) is crucial in the process of star formation. Shocks produced by supernova explosions, jets, radiation from massive stars, or galactic sp…
Turbulent diffusion of streaming cosmic rays in compressible, partially ionised plasma
Matt L. Sampson, James R. Beattie, Mark R. Krumholz +3
Cosmic rays (CRs) are a dynamically important component of the interstellar medium (ISM) of galaxies. The GeV CRs that carry most CR energy and pressure are likely confined b…
The Velocity Statistics of Turbulent Clouds in the Presence of Gravity, Magnetic fields, Radiation, and Outflow Feedback
Yue Hu, Christoph Federrath, Siyao Xu +1
The interaction of turbulence, magnetic fields, self-gravity, and stellar feedback within molecular clouds is crucial for understanding star formation. We study the effects of self…
Fundamental scales in the kinematic phase of the turbulent dynamo
Neco Kriel, James R. Beattie, Amit Seta +1
The turbulent dynamo is a powerful mechanism that converts turbulent kinetic energy to magnetic energy. A key question regarding the magnetic field amplification by turbulence, is,…
