Using the Green Bank Telescope (GBT), astronomers from West Virginia University and elsewhere have observed two distant pulsars identified with the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). Results of the observational campaign, presented October 27 on the arXiv preprint server, deliver important insights into the properties of these two pulsars.

For the first time, an international research team led by the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has demonstrated that applying pixelized strong-lensing modeling on a galaxy cluster scale can significantly improve the precision of the inferred Hubble constant (H0)—a key parameter that describes the expansion rate of the universe.

A few days ago, I wrote about non-singular black hole models, specifically one known as the Hayward model. Since its introduction in 2006, several variations of the Hayward model have been introduced, including a rotating model similar to the Kerr metric used to study the supermassive black holes we’ve observed directly. This raises an interesting […]
Far from Earth, in the vast expanses of space between stars, exists a treasure trove of carbon. There, in what scientists call the “interstellar medium,” you can find a wide range of organic molecules—from honeycomblike polycyclic aromatic hydrocarbons (PAHs) to spheres of carbon shaped like soccer balls.
