Prospects of Detecting a Jet in Sagittarius A* with Very-long-baseline Interferometry
Event Horizon Telescope (EHT) images of the horizon-scale emission around the Galactic center supermassive black hole Sagittarius A* (Sgr A*) favor accretion flow models with a jet component. However, this jet has not been conclusively detected.

The inner 300 parsecs of the Milky Way seen by H.E.S.S.: a Pevatron in the Galactic Centre
The Galactic Centre region has been observed by the High Energy Stereoscopic System (H.E.S.S.) array of ground-based Cherenkov telescopes since 2004 leading to the detection of the very-high-energy γ-ray source HESS J1745-290 spatially coincident with ...

Probabilistic Interpolation of Sagittarius A*’s Multiwavelength Light Curves Using Diffusion Models
Understanding the variability of Sagittarius A* (Sgr A*) requires coordinated, multiwavelength observations that span the electromagnetic spectrum. In this work, we focus on data from four key observatories: Chandra in the X-ray (2–8 keV), GRAVITY on the

On Sagittarius A* - Theory and Observations
Massive and supermassive dust spheres (with a zero internal pressure) collapse to full globes of finite volumes, whose surfaces have the properties of the event horizon around a mass-point. This fact explains the observational data concerning Sagittarius A* (SgrA*). By virtue of Hilbert's repulsive effect, both the event horizon of a mass-point and the
