Microlensing Hack Session

Webpage for the microlensing hack session at the CCA, January 30 -- February 1 2019.



This hack session will focus on unsolved problems in modeling microlensing events. It will be held jointly with the annual microlensing workshop. The primary goal of the hack session is to engage people outside the traditional microlensing community in open problems in microlensing research.

Open problems include:

See the projects page for more detailed descriptions.

The resources page has a list of useful references including links to public tools and datasets.


Microlensing 23 will be held January 28, 2019 – February 1, 2019 at the Center for Computational Astrophysics in New York City. A scientific conference will be held the first 2.5 days (Monday through Wednesday morning). The last 2.5 days (Wednesday afternoon through Friday) will be devoted to hacking. A tentative schedule is available here.

Hack Session participants are welcome and encouraged to attend the full week to get a fully immersive introduction to microlensing. Many of the talks will cover recent analyses of microlensing data, including ongoing challenges, which will provide a sense of the state of the field. However, it is not necessary to attend the conference in order to participate in the hack session.

To register for the Conference and/or Hack Session, please visit the main conference website (https://microlensing.science/23/). To receive a notification when registration opens, please go to https://groups.google.com/d/forum/ulens-hack and click apply for membership.

Guidelines for Collaboration

To ensure transparency and openness, we have adopted the collaboration policy developed for the Gaia Sprints. This policy recommends that participants agree to the following:

All participants will be expected to openly share their ideas, expertise, code, and interim results. Project development will proceed out in the open, among participants and in the world.

Participants will be encouraged to change gears, start new collaborations, and combine projects. Any participant who contributes significantly to a project can expect co-authorship on resulting scientific papers, and any participant who gets significant contributions to a project is expected to include those contributors as co-authors.

These rules make it inadvisable to bring proprietary data sets or proprietary code, unless the participant bringing such assets has the rights to open them or add collaborators.

Be a Nice Person

Code of Conduct

The organizers are committed to making this meeting productive and enjoyable for everyone, regardless of gender, sexual orientation, disability, physical appearance, body size, race, nationality or religion. We will not tolerate harassment of participants in any form.

Please follow these guidelines:

Participants asked to stop any inappropriate behaviour are expected to comply immediately. Attendees violating these rules may be asked to leave the event at the sole discretion of the organizers without a refund of any charge.

Any participant who wishes to report a violation of this policy is asked to speak, in confidence, to [TBD man] and [TBD woman].

This code of conduct is based on the “London Code of Conduct”, as originally designed for the conference “Accurate Astrophysics. Correct Cosmology”, held in London in July 2015.
