Summer School

AstroHackWeek is, in part, a summer school. The mornings will offer lectures and exercises covering essential skills for working effectively with large astronomical datasets. Past years have seen topics such as machine learning, Bayesian inference, frequentist statistics, databases, numerical Python, and visualization. Check out last year's recorded lectures.

Unconference & Hackathon

AstroHackWeek is also an unconference and hackathon. The afternoon every day is entirely unstructured, and offers opportunities for collaborative research, breakout sessions on special topics, and application of the concepts covered during the morning sessions. Come with a project in mind, join someone else's or apply a new skill to an old problem.

(Past) Lecturers

Below is the line-up of tutorial lecturers in our previous conferences.
We anticipate a similar set of high-profile speakers for AstroHackWeek 2018.
Stay tuned for details!


Day 1 Data Visualization Daniela Huppenkothen, Ellianna Schwab Abrahams
Day2 Bayesian Inference and Sampling Methods Ruth Angus, Dan Foreman-Mackey
Day 3 Machine Learning Theory Iain Murray, Gilles Louppe
Day 4 Practical Machine Learning, Likelihood-Free Inference Zack Akil, Iain Murray, Dan Foreman-Mackey
Day 5 All-Day Hacking!

For the full schedule, see here.

To get an idea of the content, you can check out the recorded lectures from 2015 and 2016 or the lecture materials (also for 2015, 2016 and 2017) on github.

Code of Conduct

During Astro Hack Week, we require participants to follow the code of conduct for the workshop which can be found on our code of conduct page. If you have any questions about the workshop, you can reach the organizing committee at astrohackweek@gmail.com.

Travel and Lodging

The closest large airport to the Lorentz Center@Oort in Leiden is the Schiphol Amsterdam airport. Trains to Leiden Central Train Station (direction Den Haag or Vlissingen) depart every 15 minutes and take about 20 minutes (and cost 5-10 EUR). The trip from the Station to the Center takes about 30min by foot, or a short trip by taxi or bus (buses 43 or 57). More information can be found here: http://www.lorentzcenter.nl/howto.php.

Astro Hack Week is a part of the Moore-Sloan Data Science Environments at University of California Berkeley, New York University, and the University of Washington. It is made possible by the following sponsors:


Dear colleagues,

Applications are open for the fifth Astro Hack Week! The 2018 edition will be held at the Lorentz Center@Oort, Leiden, The Netherlands, from August 6 to August 10, 2018. All scientists, including graduate students, senior undergraduates, faculty, postdocs, as well as anyone whose work relates to astronomy outside academia, are invited to apply to attend.

Due to the interactive nature of the workshop and our space constraints, we expect to cap attendance at approximately 50 people.

Astro Hack Week is a mixture of data analysis summer school and unconference-enabled collaborative research. There are no formal prerequisites. Participants will learn the theoretical foundation of, and practical knowledge in, statistical and machine learning methods crucial to modern astronomical data analysis. We welcome participants to bring their own research projects with them; Astro Hack Week is a great place to apply new skills and methods, and work with others to move these projects forward. It is also an opportunity to work on something new, and we encourage participants to apply their technical knowledge to outstanding problems in the astronomical community.

For more information, please see our website at http://astrohackweek.org. The application is available here.

We hope to see you in Leiden in August! Please forward this announcement to anyone who may be interested.

Sincerely, the Astro Hack Week organizing committee:

Lauren Anderson,
Daniela Huppenkothen,
Boris Leistedt,
