Science Goals

Cosmic Magnetism Research

Cosmic Magnetism

Mapping interstellar and cosmic magnetic fields through dust extinction polarization, providing 2D tomography of plane-of-sky fields.

3D Cloud Structure Research

3D Cloud Structure

Potentially revealing the three-dimensional structure of high-latitude diffuse clouds through polarimetry.

Dust Properties Research

Dust Properties

Examining dust alignment and properties in various environments.

Technology

Full Stokes Polarimetry

Simultaneous measurement of all four Stokes parameters (I, Q, U, V) in a single observation, providing complete polarization characterization.

Mosaic Array Design

Each of the 48 telephoto lenses generates its own image with individual polarizers, enabling unprecedented wide-field capabilities.

Low Surface Brightness

Novel refractive optics reduce light scattering by an order of magnitude compared to conventional telescopes.

Code of Conduct

Our Mission

Our goal is to advance scientific knowledge and deepen our understanding of this fascinating universe. We believe that exciting discoveries emerge when we foster a welcoming and supportive environment that embraces creativity, innovative thinking, and diverse perspectives.

Our Commitment and Standards

Passionate about unraveling the mysteries of our universe, we are dedicated to creating an inspiring and caring research environment that provides enriching, curiosity-driven experiences for all participants. We welcome and value all individuals regardless of age, nationality, race, ethnicity, gender, sexual identity and orientation, political views, personal appearance, socio-economic background, educational history, level of experience, physical or cognitive abilities, or any other aspect of personal identity.

As members of the DragonflyPol collaboration, we are committed to:

  • Treating everyone with dignity, respect, and professionalism
  • Fostering open, constructive scientific discussions
  • Enthusiastically supporting each other's professional growth and development
  • Creating an atmosphere where everyone feels welcome to contribute ideas and ask questions

We are united in our mission to push the boundaries of scientific knowledge together. To achieve this, we maintain zero tolerance for discriminatory behavior, harassment, intimidation, or any conduct that undermines our collaborative spirit.

Scientific Integrity and Attribution

Scientific integrity is fundamental to our work. We expect all members and collaborators to:

  • Properly acknowledge and cite others' contributions, ideas, and work
  • Maintain the highest standards of research ethics
  • Give appropriate credit in publications, presentations, proposals, and informal discussions
  • Respect intellectual property and collaborative agreements

Alignment with Dragonfly Values

We adopt and uphold the principles outlined in the Dragonfly Telescope Code of Conduct, which provides additional guidelines for respectful collaboration and professional conduct within the broader Dragonfly community.

Together, we work not only to study the universe, but to foster a community that reflects the best of human curiosity and cooperation.

Questions or concerns about this Code of Conduct can be directed to the Principal Investigators.
