Black Hole

The 2022 Fifa Soccer World Cup is taking place in a country land that legislates against gays and lesbians, runs its obscenely wealthy economy off fossil fuels – and whose stadiums were built on the corpses of Bangladeshi slave labour, writes Simon Reader. And various half-hearted attempts to register their…

First, radio telescopes and then X-ray telescopes operated by NASA and the European Space Agency provided observational evidence for jets and other AGN outflows. Astronomers, including Weaver, have cobbled an explanation for their genesis during the past 30 to 40 years by tying together optical, radio, ultraviolet, and X-ray evidence.…

According to scientists, the engine that powers energetic and short-lived gamma-ray bursts must always come from a newly formed black hole. However, a new study contradicts this scientific orthodoxy. The study by Dr. Nuria Jordana-Mitjans at the University of Bath suggests that some short-duration GRBs are triggered by the birth…

LONDON (AP) — Britain’s Treasury chief warned Sunday of a coming spending crunch and tax increases for cash-strapped Britons as he bids to fill the “black hole” in the country’s finances. Billing himself as a Scrooge figure ahead of Thursday’s Autumn Statement, when he will update Parliament on the government’s…

Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light years from Earth. A sub-type of GRB known as a short-duration GRB starts life when…

Massive black holes (BHs) at the centers of massive galaxies are ubiquitous. However, their population in dwarf galaxies remains elusive. Identification of these systems has historically relied on detecting light emitted from accreting gaseous disks close to the black holes. Without this light, they are difficult to detect. An international…
