Astronomers capture two enormous black holes merging in early universe

Astronomers have captured a rare celestial event — two enormous black holes merging.

The event, known as a quasar, took place when the universe was only three billion years old, a crucial time in its history when star formation was at its peak, helping shape the galaxies of today.

Researchers used a group of ground and space-based telescopes to discover the phenomenon in spectroscopic data.

The findings were published in the Nature science journal on Wednesday.

“We don't see a lot of double quasars at this early time and that's why this discovery is so exciting,” said Yu-Ching Chen of the University of Illinois at Urbana-Champaign, the US.

“Knowing about the progenitor population of black holes will eventually tell us about the emergence of supermassive black holes in the early universe and how frequent those mergers could be.”

In 2019, an image of a black hole was captured by scientists for the first time. It was photographed in the Messier 87 galaxy, 55 million light years from Earth.

It had a mass of more than six billion times that of the Sun and the picture helped to prove astronomers’ theories about black holes.

The black hole's magnetic field was revealed two years later in another image.

Researchers captured the massive object in polarised light — helping to reveal magnetic fields on the edge of the black hole.

The observations could shed light on how the distant galaxy is able to launch energetic jets from its core.

The black hole merger that was recently captured could help unlock more of their secrets, including how they form.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.

Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.

Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.

Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.

“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.

Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.

From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.

Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.

BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.

Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.

Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.

“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.

Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.

“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.

“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”

The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”
