Hubble Sees Two Quasars Side by Side in the Early Universe
When it comes to the brightest, most powerful objects in the Universe, not much can beat a Quasar. A Gamma Ray Burst from a supernova might be more energetic, but doesn’t last very long. Quasars, by comparison, can churn out 1000 times the radiation of the Milky Way, and keep doing it for hundreds of millions of years. They get all this energy from the supermassive black holes that live at the center of galaxies. As material falls towards the black hole, an accretion disk forms around it: a swirling cloud of energetic material which heats up through friction and releases electromagnetic radiation. The resulting Quasar can be so bright it drowns out the light from the rest of its galaxy from our perspective. On April 5 th , researchers announced the discovery of a rare double quasar in the early Universe. The two quasars are gravitationally bound, spiraling in towards each other. Their host galaxies are in the process of merging, and the supermassive black holes generating the quasars will also eventually collide and merge.

It is actually telling us that this population exists, and now we have a method to identify double quasars that are separated by less than the size of a single galaxy.” As bright as quasars are, detecting – and interpreting – the signals received from distant quasars is not easy. This pair of quasars existed just three billion years after the Big Bang, during a time period known as cosmic noon: the era between 10 and 11 billion years ago when star formation in the Universe was at its peak. They are very, very distant objects. It took a large collaboration and a half dozen telescopes to achieve this result. The two objects are named after their Sloan Digital Sky Survey designations J0749 + 2255, and were identified as a double quasar using the European Space Agency’s Gaia spacecraft. Confirming the characterization of the object required observations in infrared from both the Hubble Space Telescope and the W.M. Keck Observatories in HAWAII. Additional information about the objects in other wavelengths were gathered using International Gemini Observatory (optical and near-infrared), the Karl G. Jansky Very Large Array (radio), and NASA’s Chandra X-ray Observatory (X-ray). Like putting together a puzzle, each wavelength offered different information about the quasars, and helped researchers understand what was going on in this distant binary galaxy system. Hubble’s powerful resolution also allowed them to rule out the possibility that they were actually just seeing the same quasar twice due to the wonky effects of gravitational lensing. The double quasars J0749 + 2255 are so close together that they are separated by less than the space of a single galaxy, so resolving them at a distance of 10-11 billion light years away is an incredible feat. NASA’s upcoming Nancy Grace Roman telescope will be an ideal tool for finding more examples of double quasars. It will have a similar resolution to Hubble, but with a wider field of view to image more of the sky at once. With a larger sample size, astronomers will be able to make better models of galactic evolution in the early Universe.

Star Wars Director Says It's About Time A Woman Makes A Star Wars Movie
Jan 02, 2024
Oscar-winning documentary filmmaker Sharmeed Obaid-Chinoy is directing an upcoming Star Wars movie that brings back Daisy Ridley in the role of Rey. Obaid-Chinoy will become the first woman to direct a Star Wars film, dating back to the franchise's origins in the 1970s. Speaking about this, Obaid-Chinoy told CNN that she is "very thrilled" to make the movie and create something that is "very special.""We're in 2024 now, and I think it's about time we had a woman come forward to shape the story in a galaxy far, far away," she said.Obaid-Chinoy won Best Documentary, Short Subjects Academy Awards for Saving Face (2012) and A Girl in the River: The Price of Forgiveness (2015).In 2020, Lucasfilm boss Kathleen Kennedy told the BBC that a woman would eventually direct a Star Wars movie, saying that would "absolutely" happen, "without question." Victoria Mahoney was a second unit director on The Rise of Skywalker, but a woman has never claimed a top directing credit on a Star Wars movie.On the TV side of things, The Mandalorian has featured a number of female directors, including Deborah Chow and Bryce Dallas Howard. Chow went on to direct the Obi-Wan TV series, too.Another high-profile franchise that has never had a female director is James Bond. Producer Barbara Broccoli and Skyfall director Sam Mendes have both said they want to see a woman direct a future 007 film.As for Obaid-Chinoy's Star Wars movie, little is known about it apart from the fact that Ridley will come back to play Rey. It is expected that this film will be the first of the three new Star Wars films to come to theaters, possibly releasing in December 2025.According to a report, Peaky Blinders creator Steven Knight is writing the Rey movie, taking over for Damon Lindelof and Justin Britt-Gibson.

NBA Names Clare Akamanzi CEO Of NBA Africa
Jan 02, 2024 15:29
The NBA named Clare Akamanzi – an accomplished business executive and international trade and investment lawyer – as CEO of NBA Africa. Akamanzi will start her position on Jan. 23, 2024, and report to NBA Deputy Commissioner and Chief Operating Officer Mark Tatum. In this role, Akamanzi will oversee the NBA’s business and basketball development efforts in Africa and will be responsible for continuing to grow the popularity of basketball, the NBA and the Basketball Africa League (BAL) across the continent, including through grassroots basketball development, media distribution, corporate partnerships, and social responsibility initiatives that improve the livelihoods of African youth and families. For the last six and a half years, Akamanzi was CEO of Rwanda Development Board (RDB), where she spearheaded Rwanda’s economic development by enabling private sector growth. Under Akamanzi’s leadership, RDB implemented several business policy reforms and initiatives that led to significant investment and development for the country, including through partnerships with the BAL, Arsenal FC, Paris Saint-Germain FC, FC Bayern Munich and TIME Magazine, among others. “Clare’s business acumen, international experience and familiarity with basketball and the NBA make her the ideal executive to lead our business in Africa,” says Tatum. “NBA Africa and the Basketball Africa League are well-positioned for continued growth, and under Clare’s leadership we believe these initiatives will transform economies, communities and lives across the continent.” “I’ve seen firsthand how sports can positively impact businesses, families and communities in Africa, and the NBA and the BAL are a perfect example of that,” says Akamanzi. “The NBA has done an incredible job growing basketball and the economy around it across the continent, and I’m excited about the enormous opportunities ahead to build on that momentum.” Previously, Akamanzi was Chief Operating Officer of RDB and Head of Strategy and Policy Unit, Office of the President of the Republic of Rwanda. She has extensive international trade, business and diplomatic experience, having previously worked for the Rwandan Government at the World Trade Organization in Geneva, Switzerland and at the Rwandan Embassy in London, England. Akamanzi has worked or studied in seven different countries and holds an honorary LLD from Concordia University in Montreal, Canada, in recognition of her work in Rwanda. She earned a master’s degree in public administration from Harvard University’s Kennedy School of Government in Cambridge, Massachusetts, where she was the recipient of three prestigious awards for academic excellence and distinguished contribution to the community: the Lucius N. Littauer Fellows Award, the Raymond & Josephine Vernon Award and the Robert Kennedy Public Service Award. In addition, Akamanzi holds a Master of Laws degree in international trade and investments from the University of Pretoria in South Africa, and a Bachelor of Laws degree from Makerere University in Kampala, Uganda. Akamanzi has served on several company boards, including the World Health Organization (WHO) Foundation, ECOBANK and Aviation, Travel and Logistics (ATL) company. She was recognized by Forbes as one of Africa’s Top 50 Powerful Women in 2020.
