2023 Summer School for
in Crete

19-23 June, Department of Physics, University of Crete, Heraklion

Registration Closed

About The Summer School

The goal of the Summer School for Astrostatistics is to guide advanced undergraduates, masters and graduate students, and early postdocs in the use of the most common statistical tools for the analysis of a wide variety of data. Each topic includes an introductory part followed by a workshop (hands-on analysis of astronomical data), and poses particular emphasis on the development of coding abilities which will serve as a quick reference for everyday work.

This is the third iteration of a school hosted by the astronomy group of the Department of Physics of the University of Crete (see the previous events, held in 2019 and 2022 ).

Due to its very nature as a hands-on workshop, this event will require on site attendance: we do not provide an option for remote participation. The Department will provide the computational facilities required by the classes: the attendees do not need to use their personal computers. While some background in Python is helpful, the school is designed for interested students regardless of their programming experience.

The school will comply with all the COVID-19 regulations imposed locally (both from the Greek Government and from the University of Crete). These regulations and any updates to them will be communicated to the participants in due time: please check this page regularly for future important announcements (under the section Venue). With regard to transportation to and from Heraklion, the participants shall make sure to comply with all rules related to their specific travel plan.

Department of Physics, University of Crete, Heraklion



The Department is about 8 km from the center of Heraklion. There is a regular bus service from/to the city port (bus #20) or or airport (bus #11) to the University (direction Panepistimio / PAGNH). The municipality of Heraklion also provides an oline tool to keep track of the timetable and location of the buses (Iraklio Urban Buses), which is also available as mobile app. To reach the University on the direct bus line from the city center it is neccessary the "blue" ticket, costing 1.50€. Students enrolled in Greek universities might use the discounted "orange" ticket, but they must be ready to present a valid student card upon onbarding. Notice that bus tickets are valid for an individual ride, meaning that if your route will require changing muliple buse lines, you will need a new ticket for each of them. A detailed map and driving directions are available from the Department of Physics visitor information.

Heraklion airport is linked to the major European cities via Aegean Airlines, Olympic Air, easyJet, Ryanair, plus seasonal charter flights. Internal (Greece) flights are also provided by Ellinair and Sky Express. Daily ferry services from the Piraeus port in Athens are provided by Minoan Lines, Anek Lines, and Blue Star Ferries. These ferries reach the port of Heraklion in the early morning, and leave from Heraklio in the late evening. This schedule gives the participants more than aboundant time to reach the School location in time for the first class, and to reach the port after the conclusion of the School.


The venue complies with all the COVID-19 regulations imposed by the Greek Government and by the University of Crete.

As of now, there are no COVID restrictions for traveling to Greece (i.e., there are no testing requirements, green passes, etc.), but make sure to check the requirements of any countries/airports that you are transferring to on your way to Crete. All the information of interest to travelers can be found on the Greek National Public Health Organization website, and on the dedicated page regarding the Protocol for Arrivals in Greece.

Currently, masks are not mandatory inside the School venue.

If you do get infected by COVID, a self-isolation period of 5 days is expected. In any case, independently on the current regulation, if at any time you contract COVID you shall not physically attend the School and inform us as soon as possible to protect the health of the other attendants. If you have any special health concerns or needs, please reach out to us.


June is considered touristic high season for Crete: attendees are advised to book their accommodation well in advance. To facilitate the search, in our subscription FORM we invite the participants to indicate whether they would like to share a room. If necessary, the organizers might further help in arranging room sharing amongst interested participants.

Ideal locations to seek for an accommodation would be: 1) the old city center within the Venetian walls, or 2) along the line of the city bus route #11 or #20 for ease of transportation.


A variety of accommodations are rentable in the form of rooms or private apartments. As of the beginning of February, several options below 50€/night are still available through the common search engines, e.g. Booking or AirBnB, but the ones located in the city center will probably be fully booked soon.


The hotels listed below provide an affordable accommodation in the city center. An additional list of hotels can be found on the visitor's page of the Department of Physics of the University of Crete.


  • All the Jupyter notebooks presented at the school are publicly available at our github repository
    Follow the instructions in the README file to setup the necessary libraries and download the relevant data sets.
