Influence of quantum correction on the Schwarzschild black hole polarized image

European Physical Journal C: Particles and Fields
Using a model of an accretion disk around a Schwarzschild black hole, the analytic estimates for image polarization were derived by Narayan et al. (Astrophys J 102:912, 2021). Recently, the EHT team also obtained polarization images of the Sgr A $$^{*}$$

Why Are Physics‐Based Models Taking so Long to Run?

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Physics‐based models provide a reliable and interpretable framework based on established physical laws, allowing them to deal with unforeseen future conditions much better than statistical data‐driven methods. Physics‐based models in Earth science (e.g., climate models, hydrological models, and groundwater models) are commonly used for ...

Researchers' Well‐Being Through My Academic Career in Japan, Germany and USA

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Upon development of my academic career in Japan, Germany, and USA, I have increasingly recognized the importance of researchers' well‐being. While the research lifestyles in these three countries were distinct, it has been essential for me to maintain good well‐being for the sustainable development of my academic career.

COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction

Astronomy & Astrophysics
Aims. We investigate the redshift evolution and group richness dependence of the quiescent galaxy fraction and red sequence (RS) parameters in COSMOS galaxy groups, spanning a wide redshift range, from z = 0 to z = 3.7. Methods.

Betatron Cooling of Halo and Strahl Electrons in the Solar Wind

The Astrophysical Journal Letters
It is widely recognized that adiabatic acceleration plays an essential role in the dynamics of the solar wind electron distribution. Nevertheless, the role of electron adiabatic cooling remains poorly understood, at least from an observational standpoint.

Managing Differences in Geosciences and Computer Science: Strategies for Successful Interdisciplinary Collaboration

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The rise of quantitative geosciences approaches and accessible computer science tools have led to increasing overlap and opportunity at the boundaries of both fields. The need for both research innovation and student cross‐training has motivated new, interdisciplinary Computer Science‐Geoscience collaborations.
