Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Observed Timescales of Stellar Feedback in Star-forming, Low-mass Galaxies

The Astronomical Journal
Understanding the timescales of atomic gas turbulence is crucial to understanding the interplay between star formation and the interstellar medium (ISM). To investigate the timescales of turbulence low-mass galaxies (10 ^6.8

The H i Reservoir in Central Spiral Galaxies and the Implied Star Formation Process

The Astrophysical Journal Letters
The cold interstellar medium (ISM) as the raw material for star formation is critical to understanding galaxy evolution. It is generally understood that galaxies stop making stars when, in one way or another, they run out of gas. However, here we provide

Cool Dark Gas in Cygnus X: The First Large-scale Mapping of Low-frequency Carbon Recombination Lines

The Astrophysical Journal
Understanding the transition from atomic gas to molecular gas is critical to explain the formation and evolution of molecular clouds. However, the gas phases involved, cold H i and CO-dark molecular gas, are challenging to directly observe and physically

A gas-phase “top-down” chemical link between aldehydes and alcohols

Frontiers in Astronomy and Space Sciences
IntroductionAlcohols and aldehydes represent two key classes of interstellar complex organic molecules (COMs). This work seeks to better understand their possible chemical connections, with a focus on such molecules in the sources of the star-forming ...

FAST Search for Circumstellar Atomic Hydrogen. IV. Bubbles Associated with Planetary Nebulae

The Astronomical Journal
Investigating the bubbles generated by the interaction between asymptotic giant branch stellar outflows and the interstellar medium (ISM) is pivotal for elucidating the mechanism by which evolved low- to intermediate-mass stars enrich the ISM with heavy ...

Study of H i Turbulence in the SMC Using Multipoint Structure Functions

The Astrophysical Journal
Turbulence in the interstellar medium (ISM) plays an important role in many physical processes, including forming stars and shaping complex ISM structures.

H i Content of Group Galaxies from the FAST All Sky H i Survey

The Astrophysical Journal
We investigate the atomic gas (H i ) content of galaxies in groups using early data from the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) All Sky H i survey. Taking advantage of FAST’s blind, wide-area coverage and uniform sensitivity, we

FEASTS Compared with Simulations: Abnormally Irregular and Extended H i Morphologies at a Column Density of 1018 cm−2 in TNG50 and Auriga

The Astrophysical Journal
With new atomic-hydrogen (H i ) observations of FAST Extended Atlas of Selected Targets Survey (FEASTS), we present the first statistical comparison of H i morphology between observations and cosmological simulations, focusing on low-column-density (∼10 ^

The Impact of External Gas Accretion on the Distribution of H I Gas in Galaxies

The Astrophysical Journal
Using the data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) and H i -MaNGA surveys, we build a sample of 37 gas–star misaligned galaxies with robust H i detections, which are believed to have undergone external gas accretion processes.
