2022年10月23日 · Abell 2744 is itself featured on the Wikipedia gravitational lens page. Dark matter of the galaxy cluster is causing lensing. It actually warps background galaxies even on relatively large angular distances from the cluster (what we call 'weak lensing').

2024年11月20日 · In such deep-field images, UV-faint AGN appear as little red dots, but so could star-forming galaxies or brown dwarfs. Greene et al.’s spectroscopic analysis identified broad Balmer lines of...

2014年7月15日 · A simple method for the synthesis of water-soluble carbon quantum dots (CQDs) has been developed based on chemical oxidation of starch. The structures and optical properties of the CQDs were characterized by ultraviolet–visible (UV–Vis) spectroscopy, photoluminescence spectroscopy (PL) and transmission electron microscopy.

Abell 2744 serves as a gravitational lens to the high-redshift universe in JWST observations. The UNCOVER survey reported the detection of nearly twenty z>9 galaxies behind this lensing cluster. Additionally, an unexpected new population of galaxies, referred to as "little red dots'' was discovered in the JWST data behind Abell 2744, at 3&lt ...

DTC P2744, sometimes indicated as P274400, is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (Transmission). The transmission fluid temperature sensor "B" circuit is intermittent.

2019年2月25日 · Semiconducting polymer dots (Pdots) have recently attracted considerable attention because of their photocatalytic activity as well as tunable optical band gap. In this contribution, we describe the therapeutic application of Pdots through in situ photocatalytic hydrogen generation. Liposomes were e …
