Criteria for Identifying and Evaluating Locations for the Cosmic Explorer Gravitational-Wave Observatories

Q: How can the lessons learned from the Cosmic Explorer site selection process be applied to improve the relationship between scientific facilities and local/Indigenous communities in other fields?

The Cosmic Explorer site selection process emphasizes the importance of integrating social, cultural, and environmental considerations into the evaluation of potential locations for scientific facilities. This approach can serve as a model for other fields by fostering early and ongoing engagement with local and Indigenous communities. Key lessons include: Community-Based Approach: The Cosmic Explorer project prioritizes building long-lasting relationships with local and Indigenous communities from the outset. This can be replicated in other scientific endeavors by involving community members in the planning and decision-making processes, ensuring their voices are heard and respected. Cultural Sensitivity: Understanding the historical and cultural significance of land to Indigenous peoples is crucial. Scientific facilities in other fields can adopt similar practices by conducting thorough cultural assessments and respecting Indigenous knowledge systems, which can enhance mutual trust and collaboration. Transparent Communication: The Cosmic Explorer initiative advocates for transparent communication regarding the potential impacts of scientific projects. Other fields can benefit from this by providing clear information about project goals, potential risks, and benefits, thereby fostering a sense of ownership and partnership among local communities. Shared Benefits: By aligning scientific goals with community interests, such as job creation and educational opportunities, other scientific facilities can ensure that their presence contributes positively to local economies and social structures, thereby enhancing community support. Long-Term Commitment: The Cosmic Explorer project recognizes that relationship building is a long-term process. Other scientific initiatives should adopt a similar mindset, committing to ongoing engagement and support for local communities even after the initial project phases are completed.

Q: What are the potential challenges in balancing the scientific goals of Cosmic Explorer with the interests and values of the local and Indigenous communities where the observatories may be located?

Balancing the scientific goals of Cosmic Explorer with the interests and values of local and Indigenous communities presents several challenges: Land Use Conflicts: The construction and operation of large scientific facilities like Cosmic Explorer may conflict with existing land uses, such as agriculture, conservation, or cultural practices. Navigating these conflicts requires careful negotiation and compromise to ensure that community interests are respected. Environmental Concerns: Local and Indigenous communities often have deep connections to their environment. Scientific projects may raise concerns about environmental degradation, resource depletion, or disruption of local ecosystems. Addressing these concerns necessitates thorough environmental impact assessments and the implementation of mitigation strategies. Cultural Significance: The land may hold cultural, spiritual, or historical significance for Indigenous communities. Scientific goals that do not take these values into account can lead to resistance and mistrust. It is essential for Cosmic Explorer to engage in meaningful dialogue to understand and honor these cultural connections. Economic Disparities: While scientific projects can bring economic benefits, they may also exacerbate existing inequalities within communities. Ensuring that the benefits of Cosmic Explorer are equitably distributed and that local communities are not left behind is a critical challenge. Trust Building: Establishing trust between scientific institutions and local communities can be a slow and complex process. Past experiences of exploitation or neglect can lead to skepticism towards new projects. Cosmic Explorer must demonstrate genuine commitment to community interests and values to overcome this barrier.

Q: How might the Cosmic Explorer project leverage its partnerships with local and Indigenous communities to advance broader goals of scientific equity, diversity, and inclusion?

The Cosmic Explorer project can leverage its partnerships with local and Indigenous communities to promote scientific equity, diversity, and inclusion in several ways: Inclusive Workforce Development: By collaborating with local educational institutions, including tribal colleges and minority-serving institutions, Cosmic Explorer can create pathways for underrepresented groups to enter STEM fields. This can include internships, scholarships, and training programs tailored to the needs of local communities. Community-Driven Research: Engaging local and Indigenous communities in research initiatives can ensure that scientific inquiries are relevant to their needs and priorities. This participatory approach can lead to more equitable outcomes and foster a sense of ownership over scientific endeavors. Cultural Exchange and Education: Cosmic Explorer can facilitate cultural exchange programs that highlight Indigenous knowledge systems and practices. This not only enriches the scientific community but also validates and respects the contributions of Indigenous peoples to science and environmental stewardship. Policy Advocacy: By working alongside local and Indigenous communities, Cosmic Explorer can advocate for policies that promote equity and inclusion within the broader scientific landscape. This can include supporting Indigenous rights, land protections, and equitable funding for community-led scientific initiatives. Long-Term Partnerships: Establishing enduring partnerships with local and Indigenous communities can create a framework for ongoing collaboration beyond the lifespan of the Cosmic Explorer project. This can help ensure that the benefits of scientific research are sustained and that communities continue to have a voice in future scientific endeavors.

The Cosmic Explorer project is developing criteria to identify and evaluate locations that could potentially host its next-generation gravitational-wave observatories in the United States, considering scientific performance, cost boundaries, and social factors.

Samenvatting

The Cosmic Explorer (CE) project is designing the next-generation ground-based gravitational-wave observatory, which will consist of two widely separated L-shaped observatories in the United States - one with 40 km-long arms and the other with 20 km-long arms. This order of magnitude increase in scale compared to the current LIGO-Virgo-KAGRA observatories will deliver an order of magnitude greater astronomical reach, allowing access to gravitational waves from remnants of the first stars and opening a wide discovery aperture.

The article outlines the criteria that will be used to identify and evaluate potential locations for hosting the CE observatories:

Science Performance Requirements:

Observatory footprint and land impact
Global separation and orientation of the two observatories
Environmental factors like seismicity, geology, and climate

Cost Boundaries and Access:

Civil engineering cost factors
Surrounding infrastructure
Land rights, permitting, and acquisition
Considerations for Indigenous Peoples' protections, interests, and context

Social Factors:

Understanding the communities and their interests
Evaluating quality of life factors
Assessing the broader social landscape
Establishing Indigenous and Place-based Partnerships & Responsible Siting (IPP-RS)

The article also describes the overall approach, which involves an initial suitability analysis using public data, followed by on-the-ground relationship building and assessment in collaboration with local and Indigenous communities. This iterative process aims to identify locations that can support the scientific goals of CE while also aligning with community values and interests.

Statistieken

"The scale of Cosmic Explorer is much greater; it pairs one observatory with 40 km arms and far-reaching, broad-band observations with another with 20 km arms to allow for gravitational-wave source localization and polarization information as well as tuning of its sensitivity to the (kilohertz) frequencies generated by neutron stars after they merge."
"Preliminary geographical analyses indicate that allowing for small (few km) reductions in the length of the arms from the nominal 40 km and 20 km values and allowing other opening angles each significantly increase the number of locations that can accommodate Cosmic Explorer's footprint with acceptable cost while retaining most of the target sensitivity."
"As rules of thumb, a length reduction of more than 2 km or opening angles outside the range 65–115°, would each give more than a 10 % reduction of sensitivity."

Citaten

"Cosmic Explorer will achieve an order of magnitude increase in gravitational-wave amplitude sensitivity and a bandwidth that is widened toward lower frequencies with respect to the LIGO detectors."
"Identifying and evaluating locations for major scientific facilities is a multidisciplinary process that must take into account the potential scientific performance of the instruments, cost of construction and operations, and the environmental, cultural, and socio-economic landscape."
"Building, strengthening and maintaining positive, mutually beneficial relationships with Indigenous communities is a necessary criteria for successfully siting Cosmic Explorer and a central aim of for Cosmic Explorer's Indigenous and Place-based Partnerships & Responsible Siting (IPP-RS) team."
