Astronomers witness a fast and bright outburst as a small black hole destroys star

Astronomers have used the telescopes at the Canary Islands Observatories on La Palma, including the Gran Telescopio Canarias (GTC) and the Nordic Optical Telescope (NOT), to study the evolution of an exceptionally fast and bright cosmic outburst in a small galaxy located 500 million light years away. The outburst, identified as CSS161010, reached its brightest peak in just 4 days and declined to half of this brightness in only 2.5 days, making its discovery and subsequent observations of its evolution particularly challenging

Six researchers share SEK 175 million from the Wallenberg Foundation

The importance of Arctic methane emissions for the climate, how matter is formed and broken down, evolutionary shifts in the plant kingdom, and new effective methods for producing bioactive substances that will meet future needs for medicines and advanced electronics. These are just a few examples of basic research at Stockholm University that has received funding from the Knut and Alice Wallenberg Foundation.

NASA’s Hubble finds more black holes than expected in the early universe

With the help of NASA’s Hubble Space Telescope, an international team of researchers led by scientists in the Department of Astronomy at Stockholm University has found more black holes in the early universe than has previously been reported. The new result can help scientists understand how supermassive black holes were created.
