Masers are a unique tool with which to investigate the emitting gas in the innermost regions of active galactic nuclei (AGNs) and to map accretion discs and tori orbiting around supermassive black holes (SMBHs).
This is possible thanks to the high-angular-resolution measurements made with the very long baseline interferometry (VLBI) technique.
Our regular proposal for observations is a formal request submitted by astronomers and researchers seeking to observe with the EVN. These proposals cover a variety of observational modes, including both disk-recorded and real-time electronic (e-EVN) sessions, following the current capabilities of the network. They are evaluated based on their scientific merit and technical feasibility, and successful proposals are granted access to the EVN's array of telescopes spread across Europe and beyond.
We have confirmed the association of a second FRB source, called FRB 20190520B, with a potential hypernebula. This FRB was discovered using the 500-m FAST telescope in China and appeared to be associated with a more constant source of radio waves. This more constant source of radio waves hints at a hypernebula powered by the same object that makes the bright radio bursts.

Supermassive black holes at the center of active galactic nuclei (AGN) power some of the most luminous objects in the Universe). In particular, blazars are a subclass of AGNs where a relativistic jet of plasma is ejected from the surroundings of the central engine and points towards Earth with a very low inclination angle, which makes them very bright at radio wavelengths as a consequence of Doppler beaming and suitable for very long baseline interferometric (VLBI) observations.
