Direct measurements of galaxy peculiar velocities, i.e., their
motions with respect to us beyond that expected from just the
expansion of the Universe, are undergoing a resurgence. Five years
ago, individual surveys were limited to a few thousand...
Abstract: Liquid crystal elastomers are
rubbery solids with liquid crystal mesogens incorporated into their
polymer chains. These solids combine the entropic elasticity of
rubber with the orientational phase transitions of liquid crystals.
The...
Abstract: A stochastic gravitational wave
background (SGWB) is expected to be generated from a population of
unresolved sources and potentially from early Universe processes.
In the nHz band, supermassive black hole binaries generate a SGWB,
and...
Abstract 1: Massive neutrinos suppress the
growth of cosmic structure on small, non-linear, scales. There is
thus much interest in using statistics beyond the power spectrum to
tighten constraints on the neutrino mass by extracting
additional...
Abstract: We will start discussing a new
method of how to prove exponential decay for the solutions of the
wave equation on a Schwarzschild de Sitter black hole spacetime by
exploiting a novel "relatively non-degenerate" estimate. This
estimate does...
