  • The first of ten telescopes that will make up the Magdalena Ridge Observatory Interferometer (MROI) will experience first light on the evening of Tuesday, November 29th. The MROI First Light event will be streamed live on the Magdalena Ridge Observatory website, www.mrop.nmt.edu, starting at 7:30 Mountain Time on Tuesday, November 29th.

    The MROI is an optical interferometer with an array of ten 1.4-meter diameter telescopes spread out across the mountaintop in a Y configuration, and the light from all ten telescopes can be combined to observe objects in the sky with incredible resolution.

    “Our telescopes are unique,” said Dr. Ifan Payne, the Program Director for Magdalena Ridge Observatory, “they were specially designed for interferometry and together they will create the most powerful optical array on earth.” The degree of detail is strong enough that you could almost make out the face of a person standing on the moon, or, looking from Los Angeles, you could see a dime being held by someone in New York.

    The Magdalena Ridge Observatory Interferometer (MROI) is currently under development in the Magdalena Mountains, 28 miles west of Socorro, New Mexico. The array of 10 telescopes is located on a ridge at an altitude of 10,460 above sea level and is being designed and installed in a collaboration between New Mexico Tech and the University of Cambridge under federal funding administered by the Air Force Research Lab (AFRL) which is based in Albuquerque, NM.

    “We are thrilled that we have been able to come this far with the project,” said Dr. Payne, “It has been a long journey for a complex undertaking to which so many have contributed over the years. All of us, weather permitting of course, will be celebrate First Light as being the most significant mile stone to date on that journey.”

    Work on developing the Interferometer began when scientists from the University of Cambridge in the UK joined the team at New Mexico Tech to design the ground breaking, world-class astronomical facility. There are currently three operating optical interferometers in the world, in Arizona, California and Chile, and the MROI will be up to a thousand times more powerful than any of them. In fact, depending on the wavelength, the MROI will be 100 to 200 times more powerful than the Hubble Telescope.

    The Magdalena Ridge Observatory Interferometer is funded by a Cooperative Agreement (number FA9453-15-2-0086) with the Air Force Research Laboratory (AFRL).

    • The new MATISSE instrument on ESO’s Very Large Telescope Interferometer (VLTI) has now successfully made its first observations at the Paranal Observatory in northern Chile. MATISSE is the most powerful interferometric instrument in the world at mid-infrared wavelengths. It will use high-resolution imaging and spectroscopy to probe the regions around young stars where planets are forming as well as the regions around supermassive black holes in the centres of galaxies. The first MATISSE observations used the VLTI’s Auxiliary Telescopes to examine some of the brightest stars in the night sky, including Sirius, Rigel and Betelgeuse, and showed that the instrument is working well. MATISSE (Multi AperTure mid-Infrared SpectroScopic Experiment) observes infrared light — light between the visible and microwave wavelengths of the electromagnetic spectrum, covering wavelengths from 3–13 micrometres (µm) [1]. It is a second-generation spectro-interferometer instrument for ESO’s Very Large Telescope that can take advantage of multiple telescopes and the wave nature of the light. In this way, it produces more detailed images of celestial objects than can be obtained with any existing or planned single telescope at these wavelengths. After 12 years of development by a large number of engineers and astronomers in France, Germany, Austria, the Netherlands and at ESO, and following an extensive period of demanding work installing and testing this very complex instrument, initial observations have now confirmed that MATISSE is working as expected [2]. The initial MATISSE observations of the red supergiant star Betelgeuse, which is expected to explode as a supernova in a few hundred thousand years, showed that it still has secrets to reveal [3]. The new observations show evidence that the star appears to have a different size when seen at different wavelengths. Such data will allow astronomers to further study the huge star’s surroundings and how it is shedding material into space. The principal investigator of MATISSE, Bruno Lopez (Observatoire de la Côte d’Azur (OCA), Nice, France), explains its unique power: “Single telescopes can achieve image sharpness that is limited by the size of their mirrors. To obtain even higher resolution, we combine — or interfere — the light from four different VLT telescopes. Doing this enables MATISSE to deliver the sharpest images of any telescope ever in the 3–13 μm wavelength range, where it will complement the James Webb Space Telescope’s future observations from space.” MATISSE will contribute to several fundamental research areas in astronomy, focusing in particular on the inner regions of discs around young stars where planets are forming, the study of stars at different stages of their lives, and the surroundings of supermassive black holes at the centres of galaxies. Thomas Henning, director at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany, and MATISSE co-principal investigator, comments: "By looking at the inner regions of protoplanetary discs with MATISSE, we hope to learn the origin of the various minerals contained in these discs — minerals that will later go on to form the solid cores of planets like the Earth.” Walter Jaffe, the project scientist and co-principal investigator from University of Leiden in the Netherlands, and Gerd Weigelt, co-principal investigator from the Max Planck Institute for Radio Astronomy (MPIfR), Bonn, Germany, add: “MATISSE will give us dramatic images of planet-forming regions, multiple stars, and, when working with the VLT Unit Telescopes, also the dusty discs feeding supermassive black holes. We hope also to observe details of exotic objects in our Solar System, such as volcanoes on Io, and the atmospheres of giant exoplanets.” MATISSE is a four-way beam combiner, meaning it combines the light collected from up to four of the 8.2-metre VLT Unit Telescopes or up to four of the Auxiliary Telescopes (ATs) that make up the VLTI, performing both spectroscopic and imaging observations. In doing so, MATISSE and the VLTI together possess the imaging power of a telescope up to 200 metres in diameter, capable of producing the most detailed images ever at mid-infrared wavelengths. Initial tests were made with the Auxiliary Telescopes, and further observations with the four VLT Unit Telescopes are planned during the next few months. MATISSE superimposes the light of an astronomical object from the combined light of multiple telescopes, resulting in an interference pattern that contains information about the appearance of the object, from which an image can then be reconstructed. MATISSE’s first light marks a big step forward in the scope of current optical/infrared interferometers and will allow astronomers to obtain interferometric images with finer detail over a wider wavelength range than currently possible. MATISSE will also complement the instruments planned for ESO’s upcoming Extremely Large Telescope (ELT), in particular METIS (the Mid-infrared ELT Imager and Spectrograph). MATISSE will observe brighter objects than METIS, but with higher spatial resolution. Andreas Glindemann, MATISSE project manager at ESO, concludes: “Making MATISSE a reality has involved the work of many people over many years and it is wonderful to see the instrument working so well. We are looking forward to the exciting science to come!” Notes [1] MATISSE was designed, funded and built in close collaboration with ESO, by a consortium composed of institutes in France (INSU-CNRS in Paris and OCA in Nice hosting the PI team), Germany (MPIA, MPIfR and University of Kiel), the Netherlands (NOVA and University of Leiden), and Austria (University of Vienna). The Konkoly Observatory and Cologne University have also provided some support in the manufacture of the instrument. [2] With MATISSE, the last of the suite of second generation VLT/VLTI instruments has now arrived at Paranal. For the VLTI this means that 17 years — almost exactly to the day — after obtaining first fringes with VINCI and two siderostats, the first generation of instruments has now been replaced by PIONIER, GRAVITY and MATISSE, all of them combining four telescopes (UTs or ATs) and together covering a wide range of infrared wavelengths (from 1.6–13 µm). MATISSE is the first mid-infrared interferometer that can be used to reconstruct images. [3] Betelgeuse was the first star resolved by interferometry by Michelson and Pease in 1920. It was also used as a bright test case by precursor mid-infrared interferometers — including MIDI on the VLTI.

    • 麻省理工学院的研究人员描述了一种通过消除早期设计特有的错误来源方法使原子干涉与玻色-爱因斯坦凝聚更精确。 “玻色爱因斯坦凝聚实际上是相当大的，” 麻省理工物理学研究生和论文的第一作者William Burton说。“我们知道，非常小的事物表现为行为量子，但像你和我这样的大事物不表现的非常像量子。所以我们可以看到可以伸展的量子系统那么远，还有当我们带它一起回来时他协调一致的行动。这是一个有趣的问题。” 因其在玻色-爱因斯坦凝聚的开创性工作，物理学教授沃尔夫冈·克特勒和麻省理工学院哈佛中心的其他四名成员，其中Ketterle是导演赢得了2001诺贝尔物理学奖的。
