Unveiling Galaxies at Cosmic Dawn That Were Hiding Behind the Dust

Scientists serendipitously discover two heavily dust-enshrouded galaxies that formed when the Universe was only 5% of its present age

While investigating the data of young, distant galaxies observed with the Atacama Large Millimeter/submillimeter Array, Dr. Yoshinobu Fudamoto from Waseda University and the National Astronomical Observatory of Japan noticed unexpected emissions coming from seemingly empty regions in space that, a global research team confirmed, came actually from two hitherto undiscovered galaxies heavily obscured by cosmic dust. This discovery suggests that numerous such galaxies might still be hidden in the early Universe, many more than researchers were expecting.

A schematic of the results of this research. ALMA revealed a hitherto undiscovered galaxy as it is buried deep in dust (artist’s impression in upper right) in a region where the Hubble Space Telescope could not see anything (left). Researchers serendipitously discovered the new hidden galaxy while observing an already well-known typical young galaxy (artist’s impression in lower right)

When astronomers peer deep into the night sky, they observe what the Universe looked like a long time ago. Because the speed of light is finite, studying the most distant observable galaxies allows us to glimpse billions of years into the past when the Universe was very young and galaxies had just started to form stars. Studying this “early Universe” is one of the last frontiers in astronomy and is essential for constructing accurate and consistent astrophysics models. A key goal of scientists is to identify all the galaxies in the first billion years of cosmic history and to measure the rate at which galaxies were growing by forming new stars.

Various efforts have been made over the past decades to observe distant galaxies, which are characterized by electromagnetic emissions that become strongly redshifted (shifted towards longer wavelengths) before reaching the Earth. So far, our knowledge of early galaxies has mostly relied on observations with the Hubble Space Telescope (HST) and large ground-based telescopes, which probe their ultra-violet (UV) emission. However, recently, astronomers have started to use the unique capability of the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to study distant galaxies at submillimeter wavelengths. This could be particularly useful for studying dusty galaxies missed in the HST surveys due to the dust absorbing UV emission. Since ALMA observes in submillimeter wavelengths, it can detect these galaxies by observing the dust emissions instead.

In an ongoing large program called REBELS (Reionization-Era Bright Emission Line Survey), astronomers are using ALMA to observe the emissions of 40 target galaxies at cosmic dawn. Using this dataset, they have recently discovered that the regions around some of these galaxies contain more than meets the eye.

While analyzing the observed data for two REBELS galaxies, Dr. Yoshinobu Fudamoto of the Research Institute for Science and Engineering at Waseda University, Japan, and the National Astronomical Observatory of Japan (NAOJ), noticed strong emission by dust and singly ionized carbon in positions substantially offset from the initial targets. To his surprise, even highly sensitive equipment like the HST couldn’t detect any UV emission from these locations. To understand these mysterious signals, Fudamoto and his colleagues investigated matters further.

In their latest paper published in Nature, they presented a thorough analysis, revealing that these unexpected emissions came from two previously unknown galaxies located near the two original REBELS targets. These galaxies are not visible in the UV or visible wavelengths as they are almost completely obscured by cosmic dust. One of them represents the most distant dust-obscured galaxy discovered so far.

Distant galaxies imaged with ALMA, the Hubble Space Telescope, and the European Southern Observatory’s VISTA telescope. Green and orange colors represent radiations from ionized carbon atoms and dust particles, respectively, observed with ALMA, and blue represents near-infrared radiation observed with VISTA and Hubble Space Telescopes.
REBELS-12 and REBELS-29 detected both near-infrared radiation and radiation from ionized carbon atoms and dust. On the other hand, REBELS-12-2 and REBELS-29-2 have not been detected in the near-infrared, which suggests that these galaxies are deeply buried in dust.

What is most surprising about this serendipitous finding is that the newly discovered galaxies, which formed more than 13 billion years ago, are not strange at all when compared with typical galaxies at the same epoch. “These new galaxies were missed not because they are extremely rare, but only because they are completely dust-obscured,” explains Fudamoto. However, it is uncommon to find such “dusty” galaxies in the early period of the Universe (less than 1 billion years after the Big Bang), suggesting that the current census of early galaxy formation is most likely incomplete, and would call for deeper, blind surveys. “It is possible that we have been missing up to one out of every five galaxies in the early Universe so far,” Fudamoto adds.

The researchers expect that the unprecedented capability of the James Webb Space Telescope (JWST) and its strong synergy with ALMA would lead to significant advances in this field in the coming years. “Completing our census of early galaxies with the currently missing dust-obscured galaxies, like the ones we found this time, will be one of the main objectives of JWST and ALMA surveys in the near future,” states Pascal Oesch from University of Geneva.

Overall, this study constitutes an important step in uncovering when the very first galaxies started to form in the early Universe, which in turn shall help us understand where we are standing today.

Nissan and Waseda University in Japan testing jointly developed recycling process for electrified vehicle motors

New process efficiently recovers high-purity rare-earth compounds from motor magnets, practical application targeted for mid-2020s toward carbon neutral goal

YOKOHAMA, Japan　–　Nissan Motor Co., Ltd. and Waseda University today announced the start of testing in Japan of a jointly developed recycling process that efficiently recovers high-purity rare-earth compounds from electrified vehicle motor magnets. The testing is aimed at enabling practical application of the new process by the mid-2020s.

The automotive industry is promoting vehicle electrification to tackle climate change and to realize a carbon-neutral society. Most motors in electrified vehicles use neodymium magnets, which contain scarce rare-earth metals such as neodymium and dysprosium. Reducing the use of scarce rare earths is important not only because of the environmental impact of mining and refining, but also because the shifting balance of supply and demand leads to price fluctuations for both manufacturers and consumers.

=>Press Release

To use limited and valuable resources more effectively, since 2010 Nissan has been working from the design stage to reduce the amount¹ of heavy rare-earth elements (REEs) in motor magnets. In addition, Nissan is recycling REEs by removing magnets from motors that do not meet production standards and returning them to suppliers. Currently, multiple steps are involved, including manual disassembly and removal. Therefore, developing a simpler and more economical process is important to achieve increased recycling in the future.

Since 2017, Nissan has been collaborating with Waseda University, which has a strong track record of researching non-ferrous metal recycling and smelting. In March 2020 the collaboration successfully developed a pyrometallurgy process that does not require motor disassembly.

Process overview:

provided by Nissan Motor Corporation

A carburizing material and pig iron are added to the motor, which is then heated to at least 1,400 C and begins to melt.
Iron oxide is added to oxidize the REEs in the molten mixture.
A small amount of borate-based flux, which is capable of dissolving rare-earth oxides even at low temperatures and highly efficiently recovering REEs, is added to the molten mixture.
The molten mixture separates into two liquid layers, with the molten oxide layer (slag) that contains the REEs floating to the top, and the higher density iron-carbon (Fe-C) alloy layer sinking to the bottom.
The REEs are then recovered from the slag.

Testing has shown that this process can recover 98% of the motors’ REEs. This method also reduces the recovery process and work time by approximately 50% compared to the current method because there is no need to demagnetize the magnets, nor remove and disassemble them.

Going forward, Waseda and Nissan will continue their large-scale facility testing with the aim of developing practical application, and Nissan will collect motors from electrified vehicles that are being recycled and continue to develop its recycling system.

Nissan will continue to contribute to the building of a cleaner, safer and more inclusive society as part of its efforts to develop a sustainable society. Through its Nissan Green Program 2022, Nissan is addressing four priority issues: climate change, resource dependency, air quality and water scarcity. Nissan will continue to aim for carbon neutrality and zero new material resource use, and will simultaneously promote the use of electrified vehicles and the recycling and reduced use of REEs.

¹ The Nissan Note e-POWER produced in FY2020 uses magnets with 85% fewer heavy REEs than the Nissan LEAF produced in FY2010.
