Lectures on Astrophysics

Lectures on Astrophysics provides an account of classic and contemporary aspects of astrophysics, with an emphasis on analytic calculations and physical understanding. It introduces fundamental topics in astrophysics, including the properti...

Advances in astronomy and astrophysics

Atomic Astrophysics and Spectroscopy

Spectroscopy enables the precise study of astronomical objects and phenomena. Bridging the gap between physics and astronomy, this is the first integrated graduate-level textbook on atomic astrophysics. It covers the basics of atomic physic...

Identification of periodic density structures in Solar Orbiter data: Helical structures and flux ropes

Context. Quasi-periodic density structures (PDSs) are quasiperiodic variations in the solar wind density that range from a few minutes to a few hours. They are trains of advected density structures with radial length scales LR ≈ 100 − 10 00...

Searching for galaxy cluster-scale strong lenses from the DESI legacy imaging surveys

IntroductionGalaxy cluster-scale strong gravitational lensing systems are rare yet valuable tools for investigating dark matter and dark energy, as well as providing the opportunity to study the distant universe at flux levels and spatial r...

ICESat‐2 Pointing Calibration and Geolocation Performance

Abstract ICESat‐2 science requirements are dependent on the accurate real‐time pointing control (i.e., geolocation control) and postprocessed geolocation knowledge of the laser altimeter surface returns. Prelaunch pointing alignment errors ...

Fractal aggregates in geophysics

The combination of small particles to form larger structures is important in a broad range of natural processes, including the flocculation of organic and mineral particles in rivers, estuaries, and the open sea, the growth of smoke particl...

Advances in geophysics

The critically acclaimed serialized review journal for over 50 years, Advances in Geophysics is a highly respected publication in the field of geophysics. Since 1952, each volume has been eagerly awaited, frequently consulted, and praised b...

Fractals and Chaos in Geology and Geophysics

This book introduces the fundamental concepts of fractal geometry and chaotic dynamics. These concepts are then related to a variety of geological and geophysical problems, illustrating just what chaos theory and fractals really tell us and...

Geophysics as a science

Abstract "Geophysics" means "Physics of the Earth." While in physics one tries to eliminate the effects of the gravitational, electric, and magnetic fields of the earth, in geophysics these fields, their properties and effects, and the stru...

Fractals in Geology and Geophysics

The definition of a fractal distribution is that the number of objects N with a characteristic size greater than r scales with the relation N ~ r −D . The frequency-size distributions for islands, earthquakes, fragments, ore deposits, and o...

Turbulence properties and kinetic signatures of electrons in Kelvin-Helmholtz waves during a geomagnetic storm

The Kelvin–Helmholtz instability (KHI), in its nonlinear phase, plays a significant role in transporting solar-wind plasma into Earth’s magnetosphere. This study investigates the turbulence properties and reconnection signatures observed at...
