Approximation of Daily AMS‐02 Spectra With Machine Learning Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Galaxy formation and evolution

Theoretical and Natural Science, 2023
Galaxies as the most important structures in the universe and Galaxy formation is a sequential redistribution process.The basic picture of galaxy formation was first proposed by White and Rees.The physical processes involved in galaxy formation are very numerous and complex. We know very little about most of these processes.

Formation and Evolution of Galaxies

Transactions of the International Astronomical Union, 1988
At the beginning of this review period a number of arguments were put forward against the neutrino model which became popular in 1980-1983: too high a rate of the structure evolution at the non-linear stage and the same difficulty in the galaxy formation.

Galaxy Formation and Evolution

Space Science Reviews, 2016
In this chapter, we discuss the current status of observational and computational studies on galaxy formation and evolution. In particular, a joint analysis of star-formation rates (SFRs), stellar masses, and metallicities of galaxies throughout cosmic time can shed light on the processes by which galaxies build up their stellar mass and enrich the ...
