ICTP-SAIFR is promoting monthly one-day meetings of the São Paulo community working in the related areas of Cosmology/Astrophysics/Astroparticles/Gravity to be held at the Instituto Principia. The idea is to have a light schedule, with a couple of talks and plenty of time for discussion. The main purpose is to explore synergies of the different groups.
The activity will be transmitted online by Zoom.
Next Meetings:
- April 27
- May 18

Additional Information
How to reach the Principia Institute: The meeting will be held in the first-floor auditorium of the Science Center at Principia Institute located at Rua Pamplona, 145 near the Trianon-Masp metro station.
Security issues: Although São Paulo is a relatively safe city, be careful when using cellphones on the street, avoid isolated areas at night, and be aware when crossing the street that cars may not stop for pedestrians. Also, please do not leave valuable items like laptops unattended even for short breaks.
