Summary1 On 10 April 2019, the Event Horizon Telescope collaboration announced the first-ever image of a black hole in the galaxy Messier 87 (M87). A coordinated campaign for the promotion of this high-profile science story had been in preparation between all the involved institutions since November 2018, with weekly video conferences (sometimes several a week). Six coordinated press conferences began at 15:00 CEST/13:00 UTC and the image was made public at 13:07 UTC: 1. Belgium (Brussels, English) 2. USA (Washington, D.C., English) 3. Chile (Santiago, Spanish) 4. Japan (Tokyo, Japanese) 5. Taipei (Mandarin)ray 6. Shanghai (Mandarin) News of this result was covered in most major media around the world and went viral on social media. This led to unprecedented coverage, and the numbers are still increasing. According to news chief Ray Villard at STScI, the EHT image made 3500 online articles with 4.5 billion potential readers. The Hawaiian ​ ​ Bennet Group reports similar a number for a narrower subset of the storyline: “Aggregate Readership: ​ 4,673,590,910 for reflecting media results directly attributable to Bennet Group's collaboration with JCMT ​ and SMA”. 1 This overview uses content from Peter Kurczynski (NSF)’s summary: https://perimeter.teamwork.com/files/3835517 ​ and from Eduardo Ros. 3 Several of us made the “taxi-driver test”: asking random laypeople about black holes (for instance in taxis), which led to an almost 100% coverage in the awareness of the story among random people in the ​ developed world (N = ~100). ​ ​ ​ As a result, most people on the planet now know that humans have taken a picture of a black hole. ​ ​ This has led to a significant boost for EHT, for astronomy, for science and for international ​ peaceful collaboration. In Europe, science was put on the agenda in Brussels, which was a great relief for ​ politicians and news consumers in general. To quote Astrophysicist and author Ethan Siegel2: “The story of the Event Horizon Telescope is a remarkable example of high-risk, high-reward science. During the 2009 decadal review, their ambitious proposal declared that there would be an image of a black hole by the end of the 2010s. A decade later, we actually have it. That’s an incredible achievement. It relied on computational advances, the construction and integration of a slew of radio telescope facilities, and the cooperation of the international community. Atomic clocks, new computers, correlators that could link up different observatories, and many other new technologies needed to be inserted into every one of the stations. You needed to get permission. And funding. And testing time. And, beyond that, permission to observe on all the different telescopes simultaneously. But all of this happened, and wow, did it ever pay off. We are now living in the era of black hole astronomy, and the event horizon is there for us to image and understand. This is just the beginning. Never has so much been gained by observing a region where nothing, not even light, can escape.” The Preparation of the Campaign Since November 2018 a group of more than 30 communicators and communication-savvy scientists, were brought together in weekly videocons by the EHT Outreach Working Group led by Mislav Balokovic. A Teamwork site was set up to allow the group to collaborate. The scientists in the group took a leading role in the communications work, and the excitement was very high due to the potential of the result. The main focus was on data security (containing the image and the result), and the production of content. ESO’s Calum Turner took the lead on writing up a joint press release with space for “localised” content and quotes, and this was jointly edited by the 50–100 participating communicators over the course of several weeks. Collating and integrating these comments was an unprecedented effort, and allowed everyone in the collaboration to share their inputs, concerns and views. Most of the press releases published, notably NSF, ESO and the EHT collaboration, respected the agreed format, but not all. While this approach allowed a broad range of opinions to come together, it dramatically increased the coordination workload and would have benefitted from a predefined approval structure. However, the level of coordination allowed for a broad collaborative approach, leading to many translations (including into Hawaiian, the first such case) and a common pool of impressive visuals, such as a Japanese comic. A set ​ ​ of in-depth factsheets about the EHT and the history of the science leading up to the result were never finalised and were unfortunately not published. 2 https://www.forbes.com/sites/startswithabang/2019/04/11/10-deep-lessons-from- ​ our-first-image-of-a-black-holes-event-horizon/#be8191e55e64 4 It was agreed to send out the media advisory on 1 April, despite some differing opinions among EHT partners about the form and timing of this communication. In the end, the 10 days advance notice gave journalists enough time to prepare, and created a sense of suspense in the media with lots of rumours and interest which in itself provided additional visibility to EHT partners. 5 The complexity of the campaign is illustrated with a MindMap. 6 Brussels Press Conference The Brussels press conference was held at EC's Berlaymont Building. Over 60 journalists attended the press conference in Brussels, while some 120 registered to follow it online. The YouTube live feed reached a peak of some 200 000 viewers. After the press conference, ERC President Jean-Pierre Bourguignon and Nobel Laureate Brian Schmidt opened an EHT exhibition in the Berlaymont building in Brussels. The ERC liaised between the EHT project and the European Commissioner for Research and Innovation and the Commission’s Spokesperson’s Service to meet and reconcile all partners’ interests and deliver a successful communication campaign in Europe. The Brussels live feed on YouTube had ~200,000 viewers at the peak. 7 Moedas being surrounded by journalists. The ERC has never had this kind of success. The press conference in Brussels was broadcast live by the European Commission audio-visual service. The press conference YouTube stream has by now been seen ​ ​ by 3.1 million, has had 13.6 million impressions, 72 thousand shares, 62.9 thousand interactions, 59 thousand likes, 2.3 thousand comments. After one day, it entered the top three of most viewed videos on EUTube account. It was the top video for all black hole videos on YouTube on the day of the announcement. In terms of engagement, it was the most successful EUTube video ever. More than 500 entities embedded the live stream on their websites: Le Monde, Euronews, Bloomberg, Sky, El Confidencial, Evening Standard, Agenzia Ansa, Science Alert, Le Soir, La Libre, CNET Magazine, Wired IT, T-online DE, Sputnik News; Observador PT; Quotidiano, Independent, BBC News. 8 At least 92 TV channels, including BBC News, Sky News, Deutsche Welle, TVS Slovenia, produced 648 TV reports using live satellite broadcast from the press conference or the audio-visual material prepared in advanced by the ERC and Commission’s AV service, and distributed on the day of the announcement. Washington DC Press Conference The Washington DC press conference was held at the National Press Club. There were 56 reporters in the room (roughly the same as in Brussels). According to NSF, 0.75 million saw the live webcast + 2 million impressions on Facebook Live. This is a total of 1.25 million. The YouTube stream has by now accumulated 1.1 million views.

  • Mr. Jeffery Morehouse Executive Director, Bring Abducted Children Home and Father of a Child Kidnapped to Japan
    Mr. Jeffery Morehouse Executive Director, Bring Abducted Children Home and Father of a Child Kidnapped to Japan House Foreign Affairs Committee Monday, December 10, 2018 Reviewing International Child Abduction Thank you to Chairman Smith and the committee for inviting me here to share my expertise and my personal experience on the ongoing crisis and crime of international parental child abduction in Japan. Japan is internationally known as a black hole for child abduction. There have been more than 400 U.S. children kidnapped to Japan since 1994. To date, the Government of Japan has not returned a single American child to an American parent. Bring Abducted Children Home is a nonprofit organization dedicated to the immediate return of internationally abducted children being wrongfully detained in Japan and strives to end Japan's human rights violation of denying children unfettered access to both parents. We also work with other organizations on the larger goal of resolving international parental child abduction worldwide. We are founding partners in The Coalition to End International Parental Child Abduction uniting organizations to work passionately to end international parental kidnapping of children through advocacy and public policy reform. At the beginning of this year The G7 Kidnapped to Japan Reunification Project formed as an international alliance of partners who are parents and organizations from several countries including Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The objective is to bring about a rapid resolution to this crisis affecting the human rights of thousands of children abducted to or within Japan. Many Japanese citizens and officials have shared with me that they are deeply ashamed of these abductions and need help from the U.S.

  • Introduction to Black Hole Entropy and Supersymmetry
    Introduction to black hole entropy and supersymmetry Bernard de Wit∗ Yukawa Institute for Theoretical Physics, Kyoto University, Japan Institute for Theoretical Physics & Spinoza Institute, Utrecht University, The Netherlands Abstract In these lectures we introduce some of the principles and techniques that are relevant for the determination of the entropy of extremal black holes by either string theory or supergravity. We consider such black holes with N =2andN =4 supersymmetry, explaining how agreement is obtained for both the terms that are leading and those that are subleading in the limit of large charges. We discuss the relevance of these results in the context of the more recent developments. 1. Introduction The aim of these lectures is to present a pedagogical introduction to re- cent developments in string theory and supergravity with regard to black hole entropy. In the last decade there have been many advances which have thoroughly changed our thinking about black hole entropy. Supersymmetry has been an indispensable ingredient in all of this, not just because it is an integral part of the theories we consider, but also because it serves as a tool to keep the calculations tractable. Comparisons between the macroscopic and the microscopic entropy, where the latter is defined as the logarithm of the degeneracy of microstates of a certain brane or string configuration, were first carried out in the limit of large charges, assuming the Bekenstein- Hawking area law on the macroscopic (supergravity) side. Later on also subleading corrections could be evaluated on both sides and were shown to be in agreement, although the area law ceases to hold.

  • Reasons for Lack of Diversity in Open Source: the Case Katie Bouman
    Reasons for lack of diversity in open source: The case Katie Bouman Lina Wang and Kristina Weinberger February 9, 2020 1 Introduction Open Source communities face similar problems with diversity as other areas of Computer Science. In this paper, we aim to take a look at the current situation and why diversity matters. Then, we discuss the relatively recent events around Katie Bouman and the first picture of a Black Hole as an example for some of the possible reasons for a lack of women. This is followed by an overview of other common issues that may contribute to imbalances in Open Source contributions. Finally, we spend some time looking at positive developments and initiatives aimed at bringing in more diversity. 1.1 Current Status of Diversity in Open Source It is well known that women and other minority groups tend to be underrepresented in computer science in general. This lack of diversity also extends into open source projects. According to a survey among more than 5000 randomly selected github1 users, more than 90% of all contributors to open source projects identify as male, while only around 3% identify as female [24]. The survey results show a lower percentage of women, non-binary people and racial minorities than present in the wider area of computer science [7], which is already well below the general population. While this survey only shows a narrow slice of the entire open source community and other communities around free and open technologies, it is reasonable to expect a relative lack of women and other minorities overall.
