Precision cosmology with voids: definition, methods, dynamics
We develop a new cosmic void finding technique based on methods of Lagrangian orbit reconstruction. We propose to define voids as the source point of repulsion of the comoving motion of galaxies in the Universe. We re-define the position and the ellipticity of voids in this Lagrangian framework. We discuss the advantage of this new void finder compared to existing Eulerian techniques. We then d...
متن کاملElectrical Characterization of 3d Stacked Tsv with Voids
Through-silicon via (TSV) is a key component for the vertical interconnection of a 3D IC which can provide a significant performance improvement with greatly reduced physical length of channels among vertically integrated chips. TSV technology is used both in three-dimensional stacked ICs (3D-SICs), as well as in so-called 2.5D-SICs and supports high performance, small footprint and lower power...

متن کاملCosmography with the Einstein Telescope
The Einstein Telescope, a third-generation gravitational-wave detector under a design study, could detect millions of binary neutron star inspirals each year. A small fraction of these events might be observed as gamma-ray bursts, helping to measure both the luminosity distance DL to and redshift z of the source. By fitting these measured values of DL and z to a cosmological model, it would be ...
متن کاملCosmography with cluster strong lensing
By stacking an ensemble of strong lensing clusters, we demonstrate the feasibility of placing constraints on the dark energy equation of state. This is achieved by using multiple images of sources at two or more distinct redshift planes. The sample of smooth clusters in our simulations is based on observations of massive clusters and the distribution of background galaxies is constructed using ...
