A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum
Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

Journal of Forensic Sciences, Volume 71, Issue 5, Page 2070-2087, September 2026.Abstract Smartphone manufacturers' enhanced privacy and security measures, such as File‐Based Encryption (FBE), have disrupted traditional data extraction techniques, necessitating the adoption of Full File System Extraction (FFS). FFS requires booting a smartphone, decrypting its UserData partition, and accessing files individually, a process that ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, Volume 17, Issue 4, Page 553-565, September 2026.ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Kinematics of edge-on galaxy disks
, 2002 We have obtained optical spectra and H I maps for a sample of edge-on spirals. Together with existing photometry, this data allows us to study simultaneously the 3D structure and the kinematics of galaxy disks. This is briefly illustrated for IC 2531.

Different Influence of Gas Accretion on the Evolution of Star-forming and Non-star-forming Galaxies
The Astrophysical JournalUsing integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we investigate the spatially resolved properties and empirical relations of a star-forming galaxy and a non-star-forming galaxy hosting ...

The Mechanism and Timescale of Nodal Precession: Two Nuclear Stellar Disks in the Galactic Center
Open Astronomy, 2015 A dynamical model of interacting nuclear stellar rings in the central parsec of our Galaxy is constructed. We discuss the physical sources of nodal precession and of the associated time scales.

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4
The Astrophysical JournalWe study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...
