Cosmology with Clusters of Galaxies [PDF]

Particle Physics and the Universe, 2000
I show that three independent methods utilizing clusters of galaxies - cluster dynamics and mass-to-light ratio, baryon fraction in clusters, and cluster evolution - all indicate the same robust result: the mass-density of the universe is low, Omega ~ 0.2, and the mass approximately traces light on large scales.

Improving Cycle Life and Capacity Retention in PVMPO‖Li Dual‐Ion Lithium‐Organic Batteries Using an EC‐Free and FEC Additive Containing Electrolyte

Small Methods, EarlyView.
The major bottleneck of PVMPO‐based positive electrodes is electrode degradation during extended cycling with EC‐containing electrolytes. This issue is mitigated by using EC‐free electrolytes with FEC additives, which exhibit reduced interfacial resistance, fewer surface cracks, improved capacity retention, and suppressed electrode degradation, thereby

Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX) [PDF]

EPJ Web of Conferences
Galaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster medium.

‘FROM GHETTO TO HABITUS FACTORY’ ROMA CAMPS IN ITALY: An Empirical Extension of Loïc Wacquant's Theorization

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article we apply Wacquant's conceptualization of the ghetto to an analysis of interviews conducted with Roma people living in the state‐enforced camps of Turin, Italy. We illustrate how the elements characterizing a ghetto according to Wacquant (i.e.

COMPARISON OF OPTICAL AND X-RAY MASS ESTIMATES OF THE CHANDRA GALAXY CLUSTERS AT Z < 0.1

Odessa Astronomical Publications, 2013
We used the optical data taken from SDSS DR7 galaxy and group catalog to determine the optical mass of 37 nearer Chandra galaxy clusters for comparison with the X-ray mass estimates.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

The Clustering of Galaxies

Publications of the Astronomical Society of the Pacific, 1961
Inspecti of photographs obtained with wide-angle telescopes sho' that the distribution of galaxies over the sky is distinctly nt miform. The observed dumpiness of the distribution of ga ies is believed to be due to a tendency for galaxies to occur in sters. A cluster of galaxies is usually regarded as a distinct >e of aggregate of matter.
