Gully heads suffer hydraulic and gravitational erosion triggered by rainstorms. However, how hydraulic and gravitational erosion affect the morphology evolution of the vegetation-covered loess gully heads is unclear.

Nonequilibrium thermodynamics of gravitational objective-collapse models
We investigate the entropy production in the Diósi-Penrose (DP) model, one of the most extensively studied gravity-related collapse mechanisms, and one of its dissipative extensions.

Quantum correlations in a gravitational collapse simulation with SpheriCo.jl
We report on work using a newly developed code, SpheriCo.jl, that computes the gravitational collapse of a spherical scalar field, where the scalar can be either a classical field, or a quantum field operator.

Gravitational collapse in energy-momentum squared gravity: Nature of singularities
In this paper we explore a collapsing scenario in the background of energy-momentum squared gravity (EMSG). EMSG claims to have terms that originate from the quantum gravity effects mimicking loop quantum gravity.

Gravitational collapse in pure Gauss–Bonnet theory
In this paper, we study the gravitational collapse of matter fields, which include dust, perfect fluids as well as fluids admitting bulk and shear viscosity.

Non-singular gravitational collapse through modified Heisenberg algebra
We study the effects of cut-off physics, in the form of a modified algebra inspired by Polymer Quantum Mechanics and by the Generalized Uncertainty Principle representation, on the collapse of a spherical dust cloud.

Primordial black holes at the junction
Primordial black holes (PBHs) formed during first-order phase transitions provide a powerful link between the early-universe microphysics and observable signatures today, including dark matter and gravitational waves.
