Abstract In this work, we study timelike and lightlike geodesics in Kalb–Ramond (KR) gravity around a black hole with the goal of constraining the Lorentz symmetry-breaking parameter l. The analysis involves studying the precession of the S2 star p

Abstract Recently, J. Harada proposed a theory relating gravity to the Cotton tensor, dubbed as “Cotton gravity” (CG). This is an extension of General Relativity such that every solution of the latter turns out to be a solution of the former (but

Radon gas (Rn-222) in water poses health risks due to radiation exposure, yet it's also an important tracer for studying natural systems. Sampling procedures for Rn-222 analysis are very sensitive to potential losses of the gas to the atmosphere. It
