Hello, I'm Tarl N.. I noticed that you added or changed content in an article, Tsar Bomba, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Tarl N. ( discuss ) 20:06, 26 April 2021 (UTC)

Hello, I'm Sakiv. I noticed that you recently removed content from Gamma-ray astronomy without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.
