Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.

Davos, Jan 20: India's richest 1 per cent hold more than four-times the wealth held by 953 million people who make up for the bottom 70 per cent of the country's population, while the total wealth of all Indian billionaires is more than the full-year budget, a new study said on Monday.

Releasing the study 'Time to Care' here ahead of the 50th annual meeting of the World Economic Forum (WEF), rights group Oxfam also said the world's 2,153 billionaires have more wealth than the 4.6 billion people who make up 60 per cent of the planet's population.

The report flagged that global inequality is shockingly entrenched and vast and the number of billionaires has doubled in the last decade, despite their combined wealth having declined in the last year.

"The gap between rich and poor can't be resolved without deliberate inequality-busting policies, and too few governments are committed to these," said Oxfam India CEO Amitabh Behar, who is here to represent the Oxfam confederation this year.

The issues of income and gender inequality are expected to figure prominently in discussions at the five-day summit of the WEF, starting Monday. The WEF's annual global risks Report has also warned that the downward pressure on the global economy from macroeconomic fragilities and financial inequality continued to intensify in 2019.

Concern about inequality underlies recent social unrest in almost every continent, although it may be sparked by different tipping points such as corruption, constitutional breaches, or the rise in prices for basic goods and services, as per the WEF report.

Although global inequality has declined over the past three decades, domestic income inequality has risen in many countries, particularly in advanced economies and reached historic highs in some, the Global Risks Report flagged last week.

The Oxfam report further said "sexist" economies are fuelling the inequality crisis by enabling a wealthy elite to accumulate vast fortunes at the expense of ordinary people and particularly poor women and girls.

Regarding India, Oxfam said the combined total wealth of 63 Indian billionaires is higher than the total Union Budget of India for the fiscal year 2018-19 which was at Rs 24,42,200 crore.

"Our broken economies are lining the pockets of billionaires and big business at the expense of ordinary men and women. No wonder people are starting to question whether billionaires should even exist," Behar said.

As per the report, it would take a female domestic worker 22,277 years to earn what a top CEO of a technology company makes in one year.

With earnings pegged at Rs 106 per second, a tech CEO would make more in 10 minutes than what a domestic worker would make in one year.

It further said women and girls put in 3.26 billion hours of unpaid care work each and every day -- a contribution to the Indian economy of at least Rs 19 lakh crore a year, which is 20 times the entire education budget of India in 2019 (Rs 93,000 crore).

Besides, direct public investments in the care economy of 2 per cent of GDP would potentially create 11 million new jobs and make up for the 11 million jobs lost in 2018, the report said.

Behar said the gap between rich and poor cannot be resolved without deliberate inequality-busting policies, and too few governments are committed to these.

He said women and girls are among those who benefit the least from today's economic system.

"They spend billions of hours cooking, cleaning and caring for children and the elderly. Unpaid care work is the 'hidden engine' that keeps the wheels of our economies, businesses and societies moving.

"It is driven by women who often have little time to get an education, earn a decent living or have a say in how our societies are run, and who are therefore trapped at the bottom of the economy,” Behar added.

Oxfam said governments are massively under-taxing the wealthiest individuals and corporations and failing to collect revenues that could help lift the responsibility of care from women and tackle poverty and inequality.

Besides, the governments are also underfunding vital public services and infrastructure that could help reduce women and girls' workload, the report said.

As per the global survey, the 22 richest men in the world have more wealth than all the women in Africa.

Besides, women and girls put in 12.5 billion hours of unpaid care work each and every day -- a contribution to the global economy of at least USD 10.8 trillion a year, more than three times the size of the global tech industry.

Getting the richest one per cent to pay just 0.5 per cent extra tax on their wealth over the next 10 years would equal the investment needed to create 117 million jobs in sectors such as elderly and childcare, education and health.

Governments must prioritise care as being as important as all other sectors in order to build more human economies that work for everyone, not just a fortunate few, Behar said.

Oxfam said its calculations are based on the latest data sources available, including from the Credit Suisse Research Institute's Global Wealth Databook 2019 and Forbes' 2019 billionaires list.

New Delhi, Jan 19: Reacting to a tweet by ace lawyer Indira Jaising urging her to forgive the four men on death row for brutally raping that finally took her life, Nirbhaya's mother said on Saturday: "Even if God asks me, I won't forgive them."

Speaking to news agency, over the phone, the mother who had been fighting for seven long years to send her daughter's killers to the gallows, said, "...even if god comes and asks me to forgive them, I will not. People like these (Jaising) are a blot on the society."

Commenting on Jaising's tweet, she said: "Who is she to tell or suggest to me to forgive them. What relation does she have with me. I have nothing to do with such people. She can be a relative of those (the convicts) that she is having a soft corner for."

"She is an insult to women. She is running a business in the name of human rights. She is a veteran, she should give a message to the society. But she instead will go against her own kind," she added.

Earlier in the day, Jaising had requested Nirbhaya's mother to follow the example of Congress president Sonia Gandhi, who had moved for the clemency of a woman, Nalini Murugan convicted for the assassination of her husband and former Prime Minister Rajiv Gandhi.

"While I fully identify with the pain of Nirbhaya's mother I urge her to follow the example of Sonia Gandhi who forgave Nalini and said she didn't want the death penalty for her. We are with you but against death penalty," Jaising tweeted on Friday.

A Delhi Court on Friday issued fresh death warrants against the four convicts -- Akshay, Pawan, Mukesh and Vinay in the Nirbhaya gang rape and murder case.

Additional Sessions Judge (ASJ) Satish Kumar Arora fixed 1 February as the date of execution of the four death row convicts. They will be hanged at 6am.

The move came after the prosecution moved an application seeking issuance of fresh death warrants following the rejection of the mercy plea of one of the convicts Mukesh by President Ram Nath Kovind.

The 23-year-old victim was brutally gang-raped and tortured on December 16, 2012, which later led to her death.

All the six accused were arrested and charged with sexual assault and murder. One of the accused was a minor and appeared before a juvenile justice court, while another accused committed suicide in Tihar Jail.

Four of the convicts were sentenced to death by a trial court in September 2013, and the verdict was confirmed by the Delhi High Court in March 2014 and upheld by the Supreme Court in May 2017, which also dismissed their review petitions.
