Key Responsibilities

The responsibilities of the selected candidate will include conducting and analysing photometric and spectroscopic observations of microlensing events detected by the Gaia space mission. The project aims to identify black hole microlensing candidates based on astrometric data from Gaia Data Release 4 (DR4). Events observed by the BHTOM telescope network between 2014 and 2019 will be subjected to detailed analysis and additional ground‑based follow‑up observations. As part of the project, the BHTOM.space system, used for coordinating ground‑based observations, will also be further developed.
