Dear colleagues,

This is the final reminder that the deadline to register for the 2022 North American Einstein Toolkit School is this Sunday, May 1, 2022. The school—held at the University of Idaho June 13-17, 2022—will provide an opportunity for researchers and students to gather and learn about the Einstein Toolkit.

To register for the event, please visit: https://einsteintoolkit.github.io/et2022uidaho/register.html https://einsteintoolkit.github.io/et2022uidaho/register.html

This will be a fully hybrid meeting with both in-person and remote participation welcome. Please select the in-person option at registration in case you are undecided about whether you will be able to attend in person. A nominal registration fee will be required for participants who attend in person.

A limited amount of travel support is available for participants who wish to attend in person, including waiver of registration fee. Please indicate during registration if you would like to be considered for this support.

This year, a special field trip will be offered for in-person participants to nearby LIGO Hanford, whose direct observation of the gravitational waves from a coalescing pair of black holes led to the 2017 Nobel Prize in Physics. During the visit, LIGO Hanford will be gearing up for the start of O4 (Observing Run 4), due to start at the end of this year. On the same day, virtual participants will have the opportunity to attend an Einstein Toolkit hackathon.
