The next step in the research is to perform a comprehensive analysis of this intriguing signal, and compare it with the behaviour of stellar-mass black holes in our Milky Way.

He was the first graduate student to obtain his thesis observations from … "The only other system we know which seems to do the same thing is a 100,000 times smaller stellar-mass black hole in our Milky Way, fed by a binary companion star, with correspondingly smaller luminosities and timescales. He obtained his DPhil from Sussex University based on research at the Royal Greenwich Observatory, Herstmonceux Castle. Ireland is tightening coronavirus rules but will not go into a second national lockdown - despite calls from the country's health chiefs.
Hundreds of thousands of people with mental health problems, including children as young as 10, are forcibly chained up in cages and kept in appalling conditions without medical help.
X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number of years.

It also provides the best opportunity for scientists to further investigate the nature and origin of this heartbeat signal.".

Symposia and Meetings. Lead author Dr Chichuan Jin of the National Astronomical Observatories, Chinese Academy of Sciences, said: "This heartbeat is amazing! Window cleaners were left dangling on a New York high-rise on Monday, after the platform they were using to scale the building collapsed. The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed. He was a consultant for the European Space Agency and is involved in the next generation Hubble Telescope, project.
Astronomers say this is the most long lived heartbeat ever seen in a black hole and tells us more about the size and structure close to its event horizon - the space around a black hole from which nothing, including light, can escape. Professor Done said: "The main idea for how this heartbeat is formed is that the inner parts of the accretion disc are expanding and contracting.
Matter falling on to a supermassive black hole as it feeds from the accretion disc of material surrounding it releases an enormous amount of power from a comparatively tiny region of space, but this is rarely seen as a specific repeatable pattern like a heartbeat. IAU Code of Conduct. "This shows us that simple scalings with black hole mass work even for the rarest types of behaviour.".
In his article “Lights in the sky: a search for meaning” (A&G55 3.37 June 2014) Martin Ward discussed different cultural interpretations of astronomy.This included the statement that “in Roman times the appearance of a comet when Augustus Caesar became emperor was considered a blessing of the gods”. "It proves that such signals arising from a supermassive black hole can be very strong and persistent. The black hole's heartbeat was first detected in 2007 at the centre of a galaxy called RE J1034+396 which is approximately 600 million light years from Earth. Azerbaijan's second largest city has been attacked by missiles from Armenia as the conflict ramps up, an aide to the Azerbaijani president claimed. IAU e-Newsletter Volume 2020 n° 6.

In 2018 the European Space Agency's XMM-Newton X-ray satellite was able to finally re-observe the black hole and to scientists' amazement the same repeated heartbeat could still be seen. Bars in Paris could close for two weeks and restaurants will have to put in place new sanitary protocols as the capital prepares to be placed on maximum COVID-19 alert. The signal from this galactic giant repeated every hour and this behaviour was seen in several snapshots taken before satellite observations were blocked by our Sun in 2011. The time between beats can tell us about the size and structure of the matter close to the black hole's event horizon.

Anti-virus software creator John McAfee has been detained at a Spanish airport after being indicted in the US on fraud charges, according to the Reuters news agency. The developers of a potential COVID-19 antibody treatment have moved trials to a third phase, hailing "rapid achievement" with no safety concerns to date. Seven bodies have been found in a region straddling the French-Italian border near Nice after torrential rains swept houses and roads away.
