An Interview with Professor Patrick Allitt: Who is the Professor and Who is the Student?

Profile: Patrick Allitt is Cahoon Family Professor of American History. He was an undergraduate at Oxford in England, a graduate student at the University of California Berkeley, and held postdoctoral fellowships at Harvard Divinity School and Princeton University. At Emory since 1988, he teaches courses on American intellectual, environmental, and religious history, on Victorian Britain, and on the Great Books. Author of six books, he is also presenter of seven lecture series with “The Great Courses” (www.thegreatcourses.com), including “The Art of Teaching”

The Mid-infrared Instrument for JWST and Its In-flight Performance

The Mid-Infrared Instrument (MIRI) extends the reach of the James Webb Space Telescope (JWST) to 28.5 μm. It provides subarcsecond-resolution imaging, high sensitivity coronagraphy, and spectroscopy at resolutions of λ/Δλ ∼ 100-3500, with the high-resolution mode employing an integral field unit to provide spatial data cubes. The resulting broad suite of capabilities will enable huge advances in studies over this wavelength range. This overview describes the history of acquiring this capability for JWST. It discusses the basic attributes of the instrument optics, the detector arrays, and the cryocooler that keeps everything at approximately 7 K. It gives a short description of the data pipeline and of the instrument performance demonstrated during JWST commissioning. The bottom line is that the telescope and MIRI are both operating to the standards set by pre-launch predictions, and all of the MIRI capabilities are operating at, or even a bit better than, the level that had been expected. The paper is also designed to act as a roadmap to more detailed papers on different aspects of MIRI

The Science Performance of JWST as Characterized in Commissioning

This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

A 1m Resolution Camera for Small Satellites

The paper will describe how the performance of RALCam-1, the camera flying on TopSat, which is achieving 2.8m resolution at 686km altitude, has led to the development by the Rutherford Appleton Laboratory of an advanced, low cost, low mass, 1 meter resolution camera for small satellites. This camera, now under development, will fly at 600km on a small sat further advancing the scope for affordable constellations of high resolution imaging systems. The paper will concentrate on the innovative approach of the camera and how it will overcome the problems of stability of the optical bench through launch and in the thermal environment of space. It will describe the challenges and solutions related to the data dissemination and storage for such a high resolution pan and colour imager. We will end by describing how these developments will be exploited through technology transfer into the commercial sector

Isomir results.

<p>A: The relative frequencies of all isomiR classes including exact matches to the reference. <i>nta#*</i> denote non-templated additions, <i>lv3p</i> and <i>lv5p</i> the 5' and 3' length variants and <i>mv</i> denotes variants different at both ends. Classification is according to the sRNAbench hierarchical scheme. B: Length distributions for 5' and 3' variants showing the large variation in the latter. (x-axis shows length difference from canonical form). A number of the extreme 3' trimmed sequences are possibly due to erroneous mapping of short reads <18nt.</p
