Gas, Iron, and Gravitational Mass in Galaxy Clusters: The General Lack of Cluster Evolution at z < 1.0 [PDF]
Publications of the Astronomical Society of Japan, 2000 We have analyzed the ASCA data of 29 nearby clusters of galaxies systematically, and obtained temperatures, iron abundances, and X-ray luminosities of their intracluster medium (ICM). We also estimated the ICM mass using the β model, and then evaluated the iron mass contained in the ICM and derived the total gravitating mass. This gives the largest and

The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry
Astronomische Nachrichten, EarlyView.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019. These fields were observed between 21 and 407 times sim r′$$ {r}^{\prime } $$ultaneously in (8mag≲r′≲18mag$$ 8\kern0.6em \mathrm{mag}\lesssim {r}^{\prime}\lesssim 18\kern0.6em ...

EBHIS Local Volume Galaxy Hi Survey (LVGHIS)
Astronomische Nachrichten, EarlyView.ABSTRACT Here, we present the “Local Volume Galaxy Hi Survey” (LVGHIS). It is based on the first data release of the Milky Way portion of the Effelsberg Bonn Hi‐Survey (EBHIS). We homogeneously measured the mass and dynamics of the local volume galaxies within the radial velocity limit of |vLSR|≤600kms−1$$ \mid {v}_{\mathrm{LSR}}\mid \le 600\kern0.6em \

Towards a general field equation for galaxies and galaxy clusters
Astrophysics and Space ScienceThe MONDian theory of AQUAL (AQUAdratic Lagrangian) and the theory of GRAS (GRavitational Anti-Screening) are alternatives to the theory of dark matter. When these theories are applied to galaxy dynamics they are in excellent agreement with observations including the galactic RAR (Radial Acceleration Relationship).

The Age of Questions: Truth Regimes and Subjectivity in the Era of Large Language Models
Behavioral Sciences &the Law, EarlyView.ABSTRACT This essay explores how digital technologies shape subjectivity's infra‐political constitution, focusing on large language models (LLMs) like ChatGPT or Gemini within what philosophers, inspired by Michel Foucault, term the “digital truth regime.” After defining this regime, the essay identifies five key traits of LLMs: presentism in truth ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Equine Veterinary Journal, EarlyView.Abstract Background Force plates (FP) are considered the gold standard for quantitative equine gait evaluation but are limited to experimental use. An instrumented hoof boot (IHB) with pressure sensors and an inertial measurement unit would allow clinicians to objectively assess kinetic parameters and gait symmetry.
