Dear all, We are pleased to announce that the IV VISCACHA meeting will take place at UFABC, Santo André, Brazil from 6-11 August 2023. Registration* is now officially open and the conference website is released: http://www.astro.iag.usp.br/~viscacha/ivmeeting.html *even if you did not fill in the pre-registration form you are welcome to register now. The pre-registration is not a condition for the registration. See you all in Santo André! Pieter, on behalf of the LOC. =*.*= Important dates =*.*= 16/Jun: Abstract submission deadline 07/Jul: Registration deadline 14/Jul: Programme release 06/Ago: Meeting starts. =*.*= Financial support application =*.*= We applied for financial support with the Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP). However, we don't know when we will recieve their answer, it may be as late as only a month before the meeting. Therefore, we cannot count on this support, and we strongly recommend you to look for support from other sources. Participants from São Paulo state who do not have any funding sources can request financial support to the LOC [viscacha.project@gmail.com]. There will be limited resources from FAPESP, depending on FAPESP approval. The LOC recommends that if you intend to apply for this, please make a full registration now and send your request to the LOC. =*.*= Abstract submission and registration =*.*= The meeting is planned to have approximately 12 talks, 2 round tables and 3 sprint sessions between Monday and Wednesday (no posters). Thursday and Friday will be dedicated to collaborative work having all experts together, which makes it more efficient. We encourage everyone to submit an abstract for a talk. If you think that your contribution is not developed enough for a talk, feel free to contact us in advance at viscacha.project@gmail.com. It may be that your contribution is indeed valid and useful for the discussions, as this is a collaboration meeting. The deadline for registration with an abstract is 15/Jun. If you still do not want to present a talk, but would like to participate, you are more than welcome. The round tables, sprint sessions and collaborative environment will benefit a lot from your participation. The deadline for registration without an abstract is 03/Jul. The registration fee is R$150 for undergraduate or masters students, R$250 for PhD students, R$400 for post-docs, R$600 for faculty. For non-members of the VISCACHA collaboration, the registration fee is according to their category plus R$50 extra. The registration fee must be paid upon arrival. Registration form can be found in here (it works well with Chrome and Safari, there are some reports of Firefox not working). http://www.astro.iag.usp.br/~viscacha/ivmee_registration.html Alternative link for registration: https://forms.gle/kdy2Eg1qwxRD2WH99 =*.*= Logistics: flights and hotel =*.*= We strongly recommend you to book your flights as soon as possible, because the prices are increasing fast. However, if you depend upon support from FAPESP, you can only buy it after we have their approval. Please contact the LOC if this is your case. Do not book any hotel for now, because we are talking to the nearby options to try a good agreement for all the participants.
