Towards precision SZ cluster cosmology: From Planck to the Simons Observatory [PDF]

EPJ Web of Conferences
As demonstrated by Planck, SPT, and ACT, the abundance of Sunyaev-Zeldovich-detected galaxy clusters across mass and redshift is a powerful cosmological probe.

The Effects of the Activation Energy on the Intrinsic Instability of Adiabatic and Non-Adiabatic Premixed Flames

Journal of Fluid Science and Technology, 2008
The effects of the activation energy on the intrinsic instability of adiabatic and non-adiabatic premixed flames were studied by two-dimensional unsteady calculations of reactive flows based on the compressible Navier-Stokes equation.

Flame fronts in Supernovae Ia and their pulsational stability

, 2013
The structure of the deflagration burning front in type Ia supernovae is considered. The parameters of the flame are obtained: its normal velocity and thickness. The results are in good agreement with the previous works of different authors.

Cosmological Structure Formation with Augmented Lagrangian Perturbation Theory [PDF]

, 2013
We present a new fast and efficient approach to model structure formation with Augmented Lagrangian Perturbation Theory (ALPT). Our method is based on splitting the displacement field into a long and a short-range component.

Design and performance of a toroidal radiofrequency volume coil with intrinsic electromagnetic interference rejection for low-field portable Halbach-based MRI systems. [PDF]

Magn Reson Med
Abstract Purpose One of the intrinsic limitations of low‐field MRI is low signal‐to‐noise ratio, which can be further reduced by electromagnetic interference (EMI) due to the lack of a Faraday shielded room. To address this issue, we propose a novel radiofrequency (RF) coil design that is inherently less sensitive to EMI while maintaining high receive ...

Cosmological axion and neutrino mass constraints from Planck 2015 temperature and polarization data

Physics Letters B, 2016
Axions currently provide the most compelling solution to the strong CP problem. These particles may be copiously produced in the early universe, including via thermal processes.

On the Meaning and Inapplicability of the Zeldovich Relations of Magnetohydrodynamics

, 2005
Considering a plasma with an initially weak large scale field subject to nonhelical turbulent stirring, Zeldovich (1957), for two-dimensions, followed by others for three dimensions, and Zeldovich et al. (1983) have presented formulae of the form $=f(R_M)

The Sunyaev-Zeldovich Effect and Its Cosmological Significance [PDF]

, 2001
Comptonization of the cosmic microwave background (CMB) radiation by hot gas in clusters of galaxies - the Sunyaev-Zeldovich (S-Z) effect - is of great astrophysical and cosmological significance.

Three-dimensional cellular premixed flames generated by hydrodynamic and diffusive-thermal instabilities (Effects of unburned-gas temperature and heat loss)

Nihon Kikai Gakkai ronbunshu, 2019
We dealt with three-dimensional cellular premixed flames generated by hydrodynamic and diffusive-thermal instabilities to elucidate the effects of unburned-gas temperature and heat loss.
