Kavli CMB Lensing Workshop

September 13-15, 2017 @ KIPAC/Stanford

Gravitational lensing of the Cosmic Microwave Background (CMB) will be one of the primary sources of new information about the universe from current and future surveys. While lensing measurement techniques are mature enough to have demonstrated success, the precision required from future measurements will be extremely challenging. This workshop aims to bring together current and aspiring lensing experts from around the world in an interactive workshop to discuss the current state of the field and plan for the challenges of the future.

Workshop Goals:

  • Identify and discuss challenges in current and future CMB lensing measurements.
  • Provide a space for lensing experts from different groups to dive deep into the details of lensing analysis challenges.
  • Summarize current measurements of CMB lensing with a focus on the current problems and future challenges. ¬†We hope this will include lensing reconstruction, lensing power spectrum, delensing (both T, E, and B), cross-correlations and cluster lensing mass measurements.
  • Summarize current theoretical work on lensing with a focus on future challenges.
  • Identify and plan for challenges of future CMB lensing measurements.
  • We thank the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University, and the Kavli Institute for Cosmology at Cambridge University for their generous support to make this workshop possible.

    Getting there

    The nearest airports are San Francisco International Airport (SFO) or Mineta San Jose International Airport (SJC). From the airport, transportation options include:


    If you are driving to the workshop, please email Kyle Story. We have obtained a limited number of "conference" parking permits to park on campus.
    • Searsville Lot (L22): Park in the Searsville Lot (L22), see Google maps link for directions. The "scratcher" parking passes are valid for type "E" parking spots. The walk from the parking lot to the conference room take 10-15 minutes (walking directions).
    • Additional Information: can be found at the Stanford Parking Information website.
