The afterglow may remain detectable for several years. 4, 2022, about one and two months after the eruption. This composite incorporates images taken Nov. The Hubble Space Telescope captured the infrared afterglow (circled) of the gamma-ray burst known as GRB 221009A and its host galaxy. Van Eerten, who co-led the theoretical analysis of the afterglow, said, "Other researchers working on this puzzle have also come to the conclusion that the jet was pointed directly at us-much like a garden hose angled to spray straight at you-and this definitely goes some way to explain why it was seen so brightly." Brendan O'Connor, a newly graduated doctoral student at the University of Maryland and George Washington University in Washington, DC, is the study's lead author.ĭr.
The team's findings are published June 7 in the journal Science Advances. has formulated an explanation: the initial burst (known as GRB 221009A) was angled directly at Earth and it also dragged along an unusually large amount of stellar material in its wake. Hendrik Van Eerten from the Department of Physics at the University of Bath in the U.K. Now an international team that includes Dr. To learn more, see the privacy policy.Since picking up the BOAT signal simultaneously on their giant telescopes, astrophysicists the world over have been scrambling to account for the brightness of the gamma-ray burst (GRB) and the curiously slow fade of its afterglow.

The definitions are sourced from the famous and open-source WordNet database, so a huge thanks to the many contributors for creating such an awesome free resource. In case you didn't notice, you can click on words in the search results and you'll be presented with the definition of that word (if available). For those interested, I also developed Describing Words which helps you find adjectives and interesting descriptors for things (e.g. So this project, Reverse Dictionary, is meant to go hand-in-hand with Related Words to act as a word-finding and brainstorming toolset. That project is closer to a thesaurus in the sense that it returns synonyms for a word (or short phrase) query, but it also returns many broadly related words that aren't included in thesauri. I made this tool after working on Related Words which is a very similar tool, except it uses a bunch of algorithms and multiple databases to find similar words to a search query. So in a sense, this tool is a "search engine for words", or a sentence to word converter. It acts a lot like a thesaurus except that it allows you to search with a definition, rather than a single word. The engine has indexed several million definitions so far, and at this stage it's starting to give consistently good results (though it may return weird results sometimes). For example, if you type something like "longing for a time in the past", then the engine will return "nostalgia". It simply looks through tonnes of dictionary definitions and grabs the ones that most closely match your search query. The way Reverse Dictionary works is pretty simple.
