Two post-doctoral positions (FAPESP fellowships) in São Paulo, Brazil, are available to work at the interface between Rubin/LSST observatory and standard sirens from 3rd generation gravitational wave observatories.

Applications are open for two postdoctoral positions to work on multi-messenger science, with focus on the exploitation of data from the Vera Rubin Legacy Survey of Space and Time (LSST) and 3rd generation GW observatories (Einstein Telescope/Cosmic Explorer). Combining galaxies, quasars and other sources detected with the LSST, with mergers of compact objects (black holes and neutron stars) detected by present and future facilities, represents a new frontier for connecting cosmology and fundamental physics. The synergies between maps of electromagnetic sources and gravitational wave sources offer new opportunities for probes of the universe at low and high redshifts, structure formation and the merger history traced by stellar-mass objects as well as galaxies, among other areas.

The candidates should have a solid background in at least one of the two areas of this call (gravitational waves and/or cosmology).

The FAPESP postdoctoral fellowships pay an annual tax-free salary of 120,000 Brazilian reais as well as moving costs and 12,000 reais per year for research expenses. Postdocs will also receive additional funds for travel to conferences, to invite visitors, and to organize schools and workshops.

Candidates are recommended to apply before April 30th, 2025 by sending to raulabramo@usp.br or riccardo.sturani@unesp.br their Curriculum vitae with publication list and a statement of research interests. In addition, they should arrange 2-3 researchers to send recommendation letters to either one of the above email addresses. Any questions can be sent to the same email-addresses.

Successful candidates are expected to start the postdoc before the end of the current year 2025, but otherwise the starting date is flexible.
