The structure and assembly history of cluster-size haloes in Self-Interacting Dark Matter [PDF]

open access: yes, 2017
We perform dark-matter-only simulations of 28 relaxed massive cluster-sized haloes for Cold Dark Matter (CDM) and Self-Interacting Dark Matter (SIDM) models, to study structural differences between the models at large radii, where the impact of baryonic ...

Profiles of relative permittivity and electrical conductivity from unsaturated soil water content models

open access: yesAnnals of Geophysics, 2016
A mathematical model of water diffusion in the vadose zone has been implemented for different types of soil textures in order to determine the soil water content (SWC) profiles in dependence of depth and time.

Could multiple voids explain the Cosmic Microwave Background Cold Spot anomaly? [PDF]

open access: yes, 2016
Understanding the observed Cold Spot (CS) (temperature of ~ -150 mu K at its centre) on the Cosmic Microwave Background (CMB) is an outstanding problem. Explanations vary from assuming it is just a > 3 sigma primordial Gaussian fluctuation to the imprint

Surface tension data of n-propane, n-octane and n-dodecane from nucleation simulations

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2018
The Classical Nucleation Theory (CNT) has been a dominant model in understanding the self-assembly of new thermodynamic phases. CNT provides significant explanations to processes such as aerosol formation and cloud condensation.

The Dynamics of Poor Systems of Galaxies [PDF]

open access: yes, 1999
We assemble and observe a sample of poor galaxy systems that is suitable for testing N-body simulations of hierarchical clustering (Navarro, Frenk, & White 1997; NFW) and other dynamical halo models (e.g., Hernquist 1990). We (1) determine the parameters

Quantum Chemical (QC) Calculations and Linear Solvation Energy Relationships (LSER): Hydrogen-Bonding Calculations with New QC-LSER Molecular Descriptors

open access: yesLiquids
A new method, based on quantum chemical calculations, is proposed for the thermodynamically consistent reformulation of QSPR-type Linear Free-Energy Relationship (LFER) models.

Spatiotemporal variability of water vapor investigated using lidar and FTIR vertical soundings above the Zugspitze [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Water vapor is the most important greenhouse gas and its spatiotemporal variability strongly exceeds that of all other greenhouse gases. However, this variability has hardly been studied quantitatively so far. We present an analysis of a 5-year period of

Blow up profiles for a quasilinear reaction-diffusion equation with weighted reaction

open access: yes, 2019
We perform a thorough study of the blow up profiles associated to the following second order reaction-diffusion equation with non-homogeneous reaction: $$ \partial_tu=\partial_{xx}(u^m) + |x|^{\sigma}u^p, $$ in the range of exponents $10$.
