Measurement and calibration of non-linear shear terms in galaxy cluster fields

Frontiers in Astronomy and Space Sciences
IntroductionGalaxy cluster lensing is a powerful tool for measuring the mass of galaxy clusters, but accurate shear measurement and calibration are critical to obtaining reliable results.

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Jet Interaction with Galaxy Cluster Mergers

The Astrophysical Journal
Active galactic nucleus (AGN) bubbles in cool-core galaxy clusters are believed to facilitate the transport of cosmic-ray electrons (CRe) throughout the cluster.

Unveiling the Dynamics in Galaxy Clusters: The Hidden Role of Low-Luminosity Galaxies in Coma

Universe
In this work, we study the Coma cluster, one of the richest and most well-known systems at low redshifts, to explore the importance of low-flux objects in the identification of cluster substructures.

An Evaluation of Programmed Procedural Fidelity Errors on Data‐Based Decision‐Making During Precision Teaching

Behavioral Interventions, Volume 40, Issue 4, November 2025.
ABSTRACT Research employing parametric analyses of fidelity have demonstrated that some behavior analytic procedures maintain their effectiveness when procedural fidelity is reduced. To date no research has experimentally explored the impact of procedural fidelity errors in Precision Teaching.

Has the Palomar 14 Globular Cluster Been Captured by the Milky Way?

The Astrophysical Journal
We examine a new scenario to model the outer halo globular cluster (GC) Palomar 14 (Pal 14) over its lifetime by performing a comprehensive set of direct N -body calculations.

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, Volume 157, Issue 9, Page 1948-1962, 1 November 2025.
What's new? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.
