Luminescence, or the ability to glow, isn't just for fireflies and light bulbs. It's also happening in some special chemicals called halogenated silanes. Scientists took a close look at five of these chemicals: HT, CT, IT, CS, and FS. They wanted to see how different halogens (like chlorine and iodine) and temperatures affect how these chemicals glow. First, they ch...

Black holes are some of the most mysterious objects in the universe. They come in different sizes, from stellar-mass black holes to supermassive ones. Stellar-mass black holes are found in binary systems, where they pull in matter from a companion star. This process creates different X-ray spectral states: thermal-dominant, hard, and steep power-law. These states are...
