Weak Cosmic Censorship: As Strong as Ever
Shahar Hod
Spacetime singularities that arise in gravitational collapse are always hidden inside of black holes. This is the essence of the weak cosmic censorship conjecture. The hypothesis,…
Bounds on the mass-to-radius ratio for non-compact field configurations
Shahar Hod
It is well known that a spherically symmetric compact star whose energy density decreases monotonically possesses an upper bound on its mass-to-radius ratio, . Howeve…
Einstein-Yang-Mills Solitons: The Role of Gravity
Shahar Hod
The canonical Bartnik-McKinnon solitons are regular solutions of the coupled Einstein-Yang-Mills system in which gravity may balance the repulsive nature of the Yang-Mills field. W…
Does a particle swept by a turbulent liquid diffuse?
Moshe Schwartz, Gad Frenkel, S. F. Edwards
Since the famous 1926 paper by Richardson, the relative diffusion of two particles in a turbulent liquid has attracted a lot of interest. The motion of a single particle on the oth…
Near-Extreme Black Holes and the Universal Relaxation Bound
Shahar Hod
A fundamental bound on the relaxation time τof a perturbed thermodynamical system has recently been derived, τ\geq \hbar/πT, where is the system's temperature. We demonstrate a…
