New Observational Recipes for Measuring Dynamical States of Galaxy Clusters

The Astrophysical Journal
During cluster assembly, a cluster’s virialization process leaves behind signatures that can provide information on its dynamical state. However, no clear consensus yet exists on the best way to achieve this.

Ferromagnetic Interlayer Exchange Coupling in Magnetic Topological Insulator Sandwich Heterostructures

Advanced Science, EarlyView.
A thin topological insulator (Bi2Te3) inserted between two single magnetic septuple layers of MnBi2Te4 is shown to convert the intrinsic antiferromagnetic interlayer coupling into robust ferromagnetism. As the Bi2Te3 spacer thickness increases from 1 to 4 quintuple layers, the weakening coercivity, Curie temperature, and interlayer coupling reveal ...

CLASSY. X. Highlighting Differences between Partial Covering and Semianalytic Modeling in the Estimation of Galactic Outflow Properties

The Astrophysical Journal
Feedback-driven massive outflows play a crucial role in galaxy evolution by regulating star formation and influencing the dynamics of surrounding media. Extracting outflow properties from spectral lines is a notoriously difficult process for a number of ...

Uncovering the Lipid Interface in Neurotransmission: Single Molecule Measurements of Neurotransmitters Interacting with Membranes Reveal Species Dependent Membrane Binding

Advanced Science, EarlyView.
Using single‐molecule whispering gallery mode sensors, neurotransmitter‐specific membrane binding signatures are measured that reveal intrinsically distinct interaction kinetics and orientations on a lipid membrane. Abstract Neurotransmitters (NTs) have traditionally been understood to act via aqueous‐phase receptor binding, but growing evidence ...

Alkylthienyl Side Groups in Conjugated Polymers Enable Localization of π Electron Density and Facilitate Efficient Hole Transfer

Advanced Science, EarlyView.
Resonance Raman spectroscopy is used in combination with other spectroscopic and morphology characterization techniques to unveil the mechanistic origin of the shift in synthetic strategy to alkylthienyl peripheral groups for high‐performing organic photovoltaics.

Interband Lag Variability in Active Galactic Nuclei across Zwicky Transient Facility Data from Multiple Years

The Astrophysical Journal
Interband lags in the optical continua of active galactic nuclei (AGNs) have been observed over years of monitoring, yet their physical origins remain unclear.

Imperfection in Semiconductors Leading to High Performance Devices

Advanced Science, EarlyView.
Crystalline perfection is typically pursued in semiconductors to enhance device performance. However, through modeling and experimental work, we show that defects can be strategically employed in a specific detection regime to increase sensitivity to extreme values. GaN diodes are demonstrated to effectively detect high‐energy proton beams at fluxes as
