A Spatially Resolved H i Survey of Seyfert Galaxies: The Role of Active Galactic Nucleus Feedback in Shaping Atomic Gas Reservoirs

Ruitian Li, Wang, Xin, 1966-, Daizhong Liu, Hui Shi et autres

Abstract Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir—the neutral hydrogen (H i ) phase—remains poorly constrained. We present the most extensive spatially resolved H i 21 cm survey …

Entanglement Growth from Structured Initial States in Many-Body Localized Systems

Chen Xu, Pengfei Zhang

Understanding how complex entanglement structures emerge is a central problem in quantum many-body physics. Recent work by Zhang et al. has considered structured initial states prepared by evolving a product state under a chaotic Hamiltonian for a finite time before quenching to …

How hate spreads online and why it returns: Re-entrant phases driven by collective behavior

Chen Xu, P. M. Hui, Chenkai Xia, Neil F. Johnson

The 2025 Bondi Beach mass-shooting was perpetrated by individuals inspired by ISIS (Islamic State) propaganda that increasingly featured anti-Semitic hate content following the October 2023 start of the Israel-Palestine war. Similar stories hold for other types of hate attacks, e.g. against Muslims …

Folate deficiency in utero and postnatally impairs spermatogenesis, fertility, epigenetic programming and offspring health in a mouse model

Chen Xu

Les recherches précédentes ont montrée que la folacine est un élément important requis dans la santé reproductive des mâles. Pourtant, les mécanismes moléculaires restent inconnus. L'objectif de cette recherche était de déterminer l'influence exercée par un régime alimentaire faible en folacine sur …
