Late-time Radio Brightening and Emergence of a Radio Jet in the Changing-look AGN 1ES 1927+654
The Astrophysical Journal LettersWe present multifrequency (5–345 GHz) and multiresolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic nuclei (CL-AGNs).

Active Galactic Nuclei in the Extreme Ultraviolet [PDF]
International Astronomical Union Colloquium, 1995 EUV observations could provide valuable and unique information about the nature of active galactic nuclei. I discuss their potential usefulness and review some of the main results obtained so far with the ROSAT WFC and the EUVE instruments. About three dozen sources, mostly Seyfert galaxies and BL Lacertae objects, have already been identified, and ...

Journal of Computer Assisted Learning, Volume 41, Issue 3, June 2025.ABSTRACT Background The recent advent of powerful, exam‐passing large language models (LLMs) in public awareness has led to concerns over students cheating, but has also given rise to calls for including or even focusing education on LLMs. There is a perceived urgency to react immediately, as well as claims that AI‐based reforms of education will lead ...

Solar Cycle Detected in Natural Tritium of Ice Layers Before the Nuclear Era
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.Abstract The 11‐year cycle of the solar activity affects the production rate of cosmogenic isotopes. For tritium in precipitation, it has been just recently proven that this link exists. Here we show, for the first time, a tritium ice core time series which extends back to 1923, covering a time period that avoids the presence of artificial tritium from
