The AGORA High-resolution Galaxy Simulations Comparison Project. VIII. Disk Formation and Evolution of Simulated Milky Way Mass Galaxy Progenitors at 1 < z < 5

The Astrophysical Journal
We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way–like progenitors over 1 ≤ z ≤ 5, using eight state-of-the-art cosmological hydrodynamics simulation codes in the AGORA project.

Disney's Auteur Problem: Framing Corporate Creativity in a Galaxy Far, Far Away

The Journal of Popular Culture, EarlyView.
ABSTRACT At its core, Star Wars is a franchise George Lucas has led via his auteur vision. Since Lucas handed over the franchise reins to Disney, the company has courted several other auteurs to direct new entries in the series—each of those endeavors ended problematically.

The Formation of Dwarf Galaxy Disks

The Astrophysical Journal
Dwarf galaxies are dark matter-dominated systems that are sensitive to feedback and display a diversity of baryonic morphologies. This makes them excellent probes for understanding dark matter and galaxy evolution.

Population Synthesis Models for Normal Galaxies with Dusty Disks [PDF]

Journal of Astronomy and Space Sciences, 2003
To investigate the SEDs of galaxies considering the dust extinction processes in the galactic disks, we present the population synthesis models for normal galaxies with dusty disks. We use PEGASE (Fioc & Rocca-Volmerange 1997) to model them with standard

A C‐repeat binding factor–salicylic acid (CBF–SA) module links wound‐induced evaporative cooling to tissue repair in plants

New Phytologist, EarlyView.
A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...

The Intrinsic Flattening of Galaxy Disks

The Astrophysical Journal
Highly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c / a , where c and a are, respectively, the vertical and long radial axes of the disk measured at suitable stellar densities.

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

Advanced Physics Research, Volume 5, Issue 10, October 2026.
This diagram illustrates the wavy flow configuration of the model in a Cartesian coordinate system. It represents the heat and mass transfer characteristics of ternary hybrid nanofluids over a vertically wavy surface in the presence of an induced magnetic field and double‐diffusive mixed convection.

Projection effects in barred galaxies cause the wrong interpretation of radial flows

Astronomy & Astrophysics
Galaxy disks in rotation are sometimes the site of radial flows, especially in their gas component. It is important to estimate the outflows, due to active galactic nucleus or supernovae feedback, or the inflows, due to bar gravity torques.

Disk Galaxies Are Self-similar: The Universality of the H i-to-Halo Mass Ratio for Isolated Disks

The Astrophysical Journal Letters, 2023
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies

Astronomische Nachrichten, Volume 347, Issue 8, October 2026.
ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...
