Astro-GR@Cuba 2021



Organised by Pau Amaro Seoane, Hannes Jung, Leonel Morejón and Fernando Guzmán at the Instituto Superior de Tecnologías y Ciencias Aplicadas (InSTEC) de la Universidad de La Habana, from 18-29 May 2021.

The idea of this meeting is to broaden the knowledge of topics that Cuban students of the InSTEC and other research institutes of Cuba as a way to choose their future interests. Obviously, this is not only restricted to them, so that if you are interested in the topics, please drop us an e-mail to let us know. Depending on the connection limits, we will have to select the number of attendees. We will give preference to students, then postdocs and finally professors, in that order.

The talks will not be classical talks, but “constantly-interrupted-ones“, in the sense that the speakers will have to address as many questions as the students see fit to ask to understand the topic being presented, instead of just hearing a talk. There is a difference.

Because we want to share this opportunity with any interested student, we will open the participation also to non-Cuban students. However, only Cuban students will be allowed to interrupt the speaker during the talk. The reason for this is two-fold: First, the very reason of the workshop is that they have this chance and, second, we cannot have any given number of people connecting to the talk due to the limit of attendees that jitsi has.

Non-Cubans will be able to ask questions after the conclusion of the talk.

Purpose of the transfer: Participation in Astro-GR 2021 workshop
Amount: At least 10EUR, up to you to transfer more to help

in order to cover the local expenses in Cuba to organise the workshop and to improve the internet connection of students there.

Deadline for registration: 01 May 2021

Because of the pandemic, all participants will connect via jitsi.

The details will be sent per e-mail a few days before the talks start. The password for the lectures will change daily. We ask you to please pay the fee if you want to participate in the talk and not to forward the password to anyone, since the number of connections will be limited.
