Deadline: 2026-06-30 Location: Potsdam, Germany Additional Information: https://www.aei.mpg.de/1459337/scientific-project-coordinator-and-researcher Contact: bewerbung[AT]aei.mpg.de The Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Potsdam invites applications for the position of Scientific Project Coordinator and parttime Researcher to support two ERC-funded international research projects: GWSky (Making Sense of the Unexpected in the Gravitational-Wave Sky, https://www.gwsky.org ) and MaScAmp (Mathematics of Scattering Amplitudes, https://www.mascamp.org ). GWSky brings together the Niels Bohr Institute in Copenhagen, SISSA in Trieste, and the University of California, Los Angeles. MaScAmp brings together Trinity College Dublin, the University of Oxford, and Uppsala University. **Your coordination duties** * preparing the financial and scientific reports and ensuring compliance with all grant regulations given by the European Research Council * managing and monitoring the project budgets * supporting the principal investigators in administrative matters * ensuring the timely and complete contribution of all partners to the reports * serving as the main liaison with partner organizations and the ERC project officer * organizing workshops and group activities * arranging inbound and outbound visits, local hospitality, and other events * keeping the project websites up to date * coordinating recruitment **Your profile** As Project Coordinator, you will serve as the central point of contact, ensuring smooth communication among staff across all partner institutions. You have an excellent command of English, solid research project management experience, and strong communication skills. A very good command of German is desirable. A university degree is required (a Master's, ideally a PhD), and you have experience with EU-funded or similar international research projects. You bring attention to detail, strong organizational skills, the ability to juggle multiple tasks, and a proactive approach to problem-solving. A scientific background is highly preferred. Ideally, you are a scientist who can engage with the science-facing aspects of your role, not a purely administrative profile. 20% of your working time can be devoted to a research component, through active participation in the ongoing research of the GWSky or MaScAmp projects rather than a separate, independent line of work. Research experience in gravitational-wave physics, scattering amplitudes, or a closely related area is therefore a strong asset. You work well both in a team and independently, and you remain flexible in a fast-moving research environment. Experience with project management tools, budget monitoring, and reporting is a plus. The position provides a strong foundation for a career in research project management. Remuneration is based on the Collective Wage Agreement for the Civil Service (TVoed Bund) up to pay group 13. The position is fixed-term for four years, with the possibility of extension. You will join a collegial, international team and contribute to research of the highest standing.

Concepcion is the second largest metropolitan area in Chile, with a population of approximately 1,000,000 inhabitants in its greater urban area. It is a major urban and university city, located on the banks of the Biobio River, just 12 km from the Pacific coast. Chillan, with a population of approximately 200,000 inhabitants, is nestled between the Andes and the Pacific Ocean, and is renowned as a skiing destination and for its volcanic hot springs. Both cities enjoy excellent connectivity: Santiago, the national capital, lies approximately 500 km north of Concepcion and 400 km north of Chillan, and serves as the main gateway for international flights. Concepcion's airport offers frequent domestic flights and some international connections, and is located approximately 87 km southwest of Chillan. The climate across the region is Mediterranean, with cool, wet but mild winters and warm, dry summers. Application Process: Interested candidates should submit a CV and a research statement (max. 1 page) to acidm[AT]ubiobio.cl by July 8, 2026. Please also indicate the name of your preferred sponsoring researcher within the group, and include the name and contact information of a researcher able to provide a recommendation letter. The deadline to apply for government funding is yet to be announced, but is expected to fall around August 2026.

News and Codes ============================================== 3.1. OGRe v2.0.0 release is now available! ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2026/05/02/ogre-v2-0-0-release-is-now-av... Additional Information: https://github.com/bshoshany/OGRe OGRe: An Object-Oriented General Relativity Package for Mathematica has been updated to v2.0.0! This long-anticipated update includes numerous new features, improvements, and bug fixes. Many of these are due to feature requests, bug reports, and other feedback from the scientific community - submitted on GitHub, sent by email, or even discussed in person at conferences. Highlights from the new features include: * Tensor IDs are now auto-completed, making the package much easier to use. * Built-in tensors (Riemann, Ricci, etc.) now have a more intuitive interface and are cached for better performance. * New built-in tensors: Kretschmann scalar and Weyl tensor. * Option to set a custom simplification function. * Exact sign checks to better identify tensor components that are equal up to sign. * Generate TeX code from tensors directly, in both matrix and list form. * Replacement rules can now easily be applied when displaying tensors. * Clearer notation for derivatives. * Various performance optimizations and bug fixes. * Tested and verified to accurately reproduce a wide variety of known results from differential geometry and general relativity.

Living Reviews in Relativity: "Analogue gravity" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2026/06/30/living-reviews-in-relativity-... Additional Information: https://link.springer.com/journal/41114 The open-access journal Living Reviews in Relativity has recently published a 2nd update of the following article: Carlos Barcelo', Stefano Liberati and Matt Visser Analogue gravity. Living Rev Relativ 29, 2 (2026). https://doi.org/10.1007/s41114-026-00064-9 Abstract Analogue gravity is a research programme that explores analogues of general relativistic gravitational fields within other physical systems, particularly but not exclusively in condensed matter systems, with the aim of gaining new insights into related problems. Analogue models of gravity boast a long and distinguished history, dating back to the early years of general relativity. This review article delves into the history, aims, results, and future prospects of various analogue models. We begin by presenting a particularly simple example of an analogue model, then traverse the rich history and complex array of models discussed in the literature. The last decade has witnessed significant and sustained advances in analogue gravity, resulting in hundreds of published articles, workshops, and books. The future of the analogue gravity programme looks promising, with rapid technological advances on the experimental front and the potential for analogue models to inspire innovative approaches to the problem of quantum gravity on the theoretical front. Most of all, these recent years have seen the rise of an unprecedented collaboration and interplay between different communities that we believe will set a new standard for interdisciplinary research in the years to come. Change details This Living Review has undergone a major update and upgrade, most critically adding a survey of the last 15 years of research since the previous 2011 version. The number of references has increased from 702 to 1290. There have also been significant updates in pedagogy and presentation. Detailed changes are listed in the Acknowledgments.
