A Novel Parameterization for Rapid Cooling in Supernova Remnants, with applications to the Pa 30 nebula
Miranda Pikus, Paul Duffell, Soham Mandal +1
We systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework i…
Measurement of anisotropies in Supernova Remnant observations and their interpretation using numerical models
Soham Mandal, Paul C. Duffell, Abigail Polin +1
Supernova remnants (SNRs) exhibit varying degrees of anisotropy, which have been extensively modeled using numerical methods. We implement a technique to measure anisotropies in SN…
Sculpting the Morphology of Supernova Remnant Pa 30 via Efficient Ejecta Cooling
Paul C. Duffell, Abigail Polin, Soham Mandal
We demonstrate in a proof-of-concept numerical hydrodynamics calculation that the narrow radial filamentary structures seen in Pa 30 could be generated through highly efficient coo…
Ab initio Investigation of Thermal Transport in Insulators: Unveiling the Roles of Phonon Renormalization and Higher-Order Anharmonicity
Soham Mandal, Manish Jain, Prabal K. Maiti
The occurrence of thermal transport phenomena is widespread, exerting a pivotal influence on the functionality of diverse electronic and thermo-electric energy-conversion devices.…
SPROUT: A moving mesh hydro code using a uniformly expanding Cartesian grid
Soham Mandal, Paul C. Duffell
We present the publicly available moving-mesh hydrodynamics code Sprout. Sprout solves the equations of ideal hydrodynamics on an expanding Cartesian mesh. The expanding mesh can f…
A 3D Numerical Study of Anisotropies in Supernova Remnants
Soham Mandal, Paul C. Duffell, Abigail Polin +1
We develop a suite of 3D hydrodynamic models of supernova remnants (SNRs) expanding against the circumstellar medium (CSM). We study the Rayleigh-Taylor Instability (RTI) forming a…
