🪐 Astronomy / Cosmology
4 ConnectionsNeutrinos and Heavy Element Nucleosynthesis
🪐 Astronomy / CosmologyThis chapter discusses three nucleosynthesis processes involved in producing heavy nuclei beyond the iron group that are influenced or shaped by neutrino interactions: the v process, the vp process and the r process. These processes are all related to explosive events involving compact objects, such as core-collapse supernovae and binary neutron star mergers, where an abundant amount of neutrinos are emitted. The interactions of the neutrinos with nucleons and nuclei through both charged-current
Testing Cosmic Acceleration with Type Ia Supernovae
🪐 Astronomy / CosmologyWe discuss recent evidence for an accelerating Universe from measurements of type Ia supernovae at high redshift, and describe tests of various systematic effects such as extinction and evolution that could be biasing the cosmological result. Continued observations of these objects, both over a wider wavelength region and at higher redshift, should provide strong evidence in favor or against the accelerating Universe hypothesis.

💧 HydrologyPrecipitation generates small-scale turbulent air flows the energy of which ultimately dissipates to heat. The power of this process has previously been estimated to be around 2-4 W m-2 in the tropics: a value comparable in magnitude to the dynamic power of the global circulation. Here we suggest that this previous power estimate is approximately double the true figure. Our result reflects a revised evaluation of the mean precipitation path length Hp. We investigate the dependence of Hp on surfa

Where do winds come from? A new theory on how water vapor condensation influences atmospheric pressure and dynamics
💧 HydrologyPhase transitions of atmospheric water play a ubiquitous role in the Earth's climate system, but their direct impact on atmospheric dynamics has escaped wide attention. Here we examine and advance a theory as to how condensation influences atmospheric pressure through the mass removal of water from the gas phase with a simultaneous account of the latent heat release. Building from the fundamental physical principles we show that condensation is associated with a decline in air pressure in the lo

Origin of atmospheric aerosols at the Pierre Auger Observatory using studies of air mass trajectories in South America
💧 HydrologyThe Pierre Auger Observatory is making significant contributions towards understanding the nature and origin of ultra-high energy cosmic rays. One of its main challenges is the monitoring of the atmosphere, both in terms of its state variables and its optical properties. The aim of this work is to analyze aerosol optical depth $τ_{\rm a}(z)$ values measured from 2004 to 2012 at the observatory, which is located in a remote and relatively unstudied area of the Pampa Amarilla, Argentina.

Two-phase pore-network model for evaporation-driven salt precipitation -- representation and analysis of pore-scale processes
💧 HydrologyEvaporation-driven salt precipitation occurs in different contexts and leads to challenges in case of e.g. soil salinization or stress-introducing precipitation in building material. During evaporation, brine in porous media gets concentrated due to the loss of water until the solubility limit is reached and salt precipitates. Different models on the REV-scale are available, which describe the effective behavior of the system. But several studies indicate that the controlling processes of evapor
