Testing General Relativity Using Large-scale Structure Photometric Redshift Surveys and the Cosmic Microwave Background Lensing Effect

The Astrophysical Journal Supplement Series
The E _G statistic provides a valuable tool for evaluating the predictions of general relativity (GR) by probing the relationship between gravitational potential and galaxy clustering on cosmological scales within the observable Universe.

Convolution and deconvolution based estimates of galaxy scaling relations from photometric redshift surveys

, 2010
In addition to the maximum likelihood approach, there are two other methods which are commonly used to reconstruct the true redshift distribution from photometric redshift datasets: one uses a deconvolution method, and the other a convolution.

One‐Pot Sequential Heck–Suzuki Synthesis of 5‐Styryl‐9‐Hydroxy‐1H‐phenalen‐1‐ones with Tunable Optoelectronic Properties

Asian Journal of Organic Chemistry, Volume 14, Issue 12, December 2025.
A one‐pot Heck–Suzuki three‐component reaction gives access to a library of 5‐styryl‐substituted 9‐hydroxyphenalenones. Redox potentials, absorption, and emission data, complemented by (TD)DFT electronic‐structure calculations provide a sound basis for rational structure–property relationships for the design of these multifunctional chromophores ...

Photocatalytic Activity of Ionic Carbon Nitrides is Governed by Cation‐Modulated Dark Exciton Dynamics

Advanced Science, Volume 12, Issue 42, November 13, 2025.
This study establishes a direct link between photocatalytic activity, spectroscopic properties, and theoretical analysis of structural effects on exciton behavior in ionic carbon nitrides with different cations. The exciton lifetimes and photocatalytic activity are shown to be primarily related to different dark exciton dynamics governed by changes in ...

A “3+2” Cooperation Pattern of Amphipathic AIE Phototheranostic System for Multimodal Image‐Guided Synergistic Type I/II Photodynamic‐Photothermal Therapy

Advanced Science, Volume 12, Issue 39, October 20, 2025.
A “3+2” cooperation pattern of amphipathicity PTA (named TDTMSB) with aggregation‐induced emission (AIE) features is designed and synthesized to perform near‐infrared I/II fluorescence imaging, photoacoustic imaging, photothermal imaging, and Type I/II photodynamic therapy (PDT)‐photothermal therapy (PTT) synergistic phototherapy for malignant tumors ...
