Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion

Abstract We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using JWST near-infrared (NIR) imaging and ALMA H13CO+(1–0) observations. The JWST images uncover a compact (∼0.5 pc) hub-filament system (HFS), comprising a dense central hub connected b...

New insights on mutual information in the island approach to the Page curve

Abstract In this article, we have presented one of the very important observations, regarding the behavior of mutual information of two different sets of subsystems in the after Page time scenario. This provides us with some deep insights about the redistribution of geometrical c...

Quantum steering based on partial state information

Abstract Exploiting partial knowledge of a qubit in terms of its basis-dependent measure of imaginarity, we formulate a steering criterion for bipartite qubit systems, which requires two dichotomic measurements at the untrusted side and two mutually unbiased bases at the trusted...
