The shadows and observational appearance of a noncommutative black hole surrounded by various profiles of accretions

open access: yesNuclear Physics B, 2022
The accretion around the black hole plays a pivotal role in the theoretical analysis of black hole shadow, and of the black hole observation in particular.

On tea, donuts and non-commutative geometry [PDF]

open access: yesSurveys in Mathematics and its Applications, 2018
As many will agree, it feels good to complement a cup of tea by a donut or two. This sweet relationship is also a guiding principle of non-commutative geometry known as Serre Theorem.

Gravitational probe of ꝗuantum spacetime

open access: yesPhysics Letters B
A quest for phenomenological footprints of quantum gravity is among the central scientific tasks in the rising era of gravitational wave astronomy. We study gravitational wave dynamics within the noncommutative geometry framework, based on a Drinfeld ...

On the Stability of Thin-Shell Wormholes in Noncommutative Geometry

open access: yesAdvances in High Energy Physics, 2012
This paper reexamines a special class of thin-shell wormholes that are unstable in general relativity in the framework of noncommutative geometry. It is shown that, as a consequence of the intrinsic uncertainty, these wormholes are stable to small ...
