R. Fraga Encinas MSc (Raquel)
PhD candidate - Astrophysics
I am a member of the Event Horizon telescope (EHT) Collaboration which took the first ever direct images of the black holes M87* and Sagittarius A*. My research is focused around Sagittarius A*, the black hole at the heart of our own Milky Way Galaxy and its properties. I do modelling and analyze observations of Sagittarius A* at radio wavelengths.
I am also involved in communications and outreach activities for the EHT collaboration as part of the Communication Working Group, Outreach Working Group, Social Media WG and the EHT Speakers Bureau, which is a panel that selects scientists to represent our collaboration at professional conferences.
My interests are:
- Black holes, accretion processes and plasma physics.
- Very Large Baseline Interferometry (VLBI), radioastronomy.
- Data analysis, image processing and modelling.
- Communications & outreach activities.
- Social Media Management (manager of the European accounts).
- Graphic design & creation of visual material for outreach.

- The EHT is an international collaboration that has formed to continue the steady long-term progress on improving the capability of Very Long Baseline Interferometry (VLBI) at short wavelengths in pursuit of this goal. This technique of linking radio dishes across the globe to create an Earth-sized interferometer has been used to measure the size of the emission regions of the two supermassive black holes with the largest apparent event horizons: SgrA* at the center of the Milky Way and M87* in the center of the Virgo A galaxy. In both cases, the sizes match that of the predicted silhouette caused by the extreme lensing of light by the black hole. In 2019 and 2022 our project revealed the first direct images of a black hole. More information
- BlackHoleCam is a EU-funded project to image, measure and understand the astrophysical properties of black holes. Our research tests fundamental predictions of Einstein’s theory of General Relativity. The BlackHoleCam team members are active partners of the global Event Horizon Telescope Consortium (EHT), we are the European branch of this collaboration. More information
