The SAMI Galaxy Survey revisiting Galaxy classification through high-order stellar kinematics. (2017)

, 2017
The SAMI instrument and Galaxy Survey is described in detail in Croom+ (2012MNRAS.421..872C) and Bryant+ (2015MNRAS.447.2857B). SAMI is a multi-object integral field spectrograph on the 3.9m Anglo Australian Telescope (AAT).

Cosmic Radiation Dose‐Rates for Civil Aviation in the Middle East: Vertical Structure, Solar Modulation, and Comparison With Models

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract High‐altitude balloon measurements were conducted over southern Israel (30°35′N, 34°45′E; 850 m a.s.l., geomagnetic rigidity cutoff 10.3 GV) to characterize the vertical profiles of atmospheric ionization and radiation up to ∼35 km. Six balloon launches between October 2014 and August 2016 recorded the variability of atmospheric ionization ...

Bar Instability and Formation Timescale across Toomre’s Q Parameter and Central Mass Concentration: Slow Bar Formation or True Stability

The Astrophysical Journal
We investigate the bar formation process using N -body simulations across the Toomre’s parameter Q ${}_{{\rm{\min }}}$ and central mass concentration (CMC), focusing principally on the formation timescale.

Solution of the dark matter riddle within standard model physics: from black holes, galaxies and clusters to cosmology

Frontiers in Astronomy and Space Sciences
It is postulated that the energy density of the (quantum) vacuum acts firstly as dark energy and secondly as a part of dark matter. Assisted by electric fields arising from a small charge mismatch in the cosmic plasma, it can condense on mass ...

Bridging Theory and Practice: Digital Twin Simulation of a Heat Exchanger in Laboratories for Engineering Students

Computer Applications in Engineering Education, Volume 34, Issue 5, September 2026.
ABSTRACT Digital twins serve as virtual replicas of physical systems. They can be used as a tool for engineering education by revealing the underlying principles behind unit operations. The project aimed to integrate digital twins into university engineering lab courses, complementing traditional methods by bridging the gap between experimentation and ...

The Dependency of Bar Formation Timescale on Disk Mass Fraction, Toomre Q, and Scale Height

The Astrophysical Journal
Bars are one of the most prominent galactic structures. The classical swing-amplification theory can qualitatively describe the spontaneous bar instability of stellar disks.

A steep mass transition for bar-driven interstellar medium structuring revealed by PHANGS-JWST

Astronomy & Astrophysics
Galactic bars are thought to play a critical role in the secular evolution of their hosts by, for example, reorganising the interstellar medium (ISM). We used a sample of 57 star-forming disc galaxies observed with JWST at 3 and 7.7 µm to probe how the ...

Variation in Bird Gut Microbiota Across Dietary Guilds and Migratory Strategies

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study analyzed the gut microbiota of birds from different ecological types in Nanning, Guangxi, and found that different dietary habits (omnivory, carnivory, and herbivory) and migratory strategies (migratory and resident) significantly altered the gut microbiota of birds, but migration did not increase the inter‐individual variability of gut ...

Dependency of the Bar Formation Timescale on the Halo Spin

The Astrophysical Journal
Bars are among the most prominent structures in disk galaxies. While the widely accepted swing-amplification theory provides a qualitative framework for their formation, the detailed physical processes remain incompletely understood.
