23rd International Microlensing Conference

Welcome to Microlensing 22 - Reaching Out | University of Auckland, New Zealand

We invite the microlensing community to attend the 22nd International Microlensing Conference!

For a quarter of a century, gravitational microlensing has been used as a channel for astrophysical discovery.

Microlensing is:

  • increasing our knowledge of stellar populations in the Milky Way and other galaxies,
  • constraining the frequency and mass function of compact objects, including black holes, white dwarfs, and brown dwarfs,
  • probing the structure of the inner Galaxy and the properties of the stellar population that resides there,
  • discovering Earth-mass exoplanets from the outer habitable zone out to beyond the snow line,
  • becoming a part of space-based observation programmes which are building a map of the planetary abundance in our Galaxy, including an exploration of the frequency and mass function of free-floating planets.

Our community has grown, but will need to grow further to meet the challenges put in front of us by new and existing ground and space-based observatories. Current observational efforts produce data at a rate that is a challenge to analyse with our present resources and tools. We need to address this as we move forward into an era of WFIRST/LSST microlensing.

Our theme for this meeting is loosely centered on how to prepare for the coming decade of microlensing observations and the data they will bring.

We will discuss what tools we presently have to analyse data, whether and how these can be best adopted as a standard in the field, what tools or skills are missing from our present capabilities, and how we can address these gaps. 

Microlensing has a lot to offer the broader astrophysical community. In turn, we must reach out to our colleagues in the fields of statistics, computer science, and astroinformatics to let them know of the opportunities and tensions in our field, and to build links with these communities.

The Department of Physics at the University of Auckland is committed to providing a harassment-free environment. This conference has adopted the London Code of Conduct and all participants are required to abide by this Code. If you have any questions about the Code of Conduct, please contact Nicholas Rattenbury.

We look forward to your attendance.
