The “toothbrush-relic”: evidence for a coherent linear 2-Mpc scale shock wave in a massive merging galaxy cluster? [PDF]

, 2012
Some merging galaxy clusters host diffuse extended radio emission, so-called radio halos and relics. Here we present observations between 147 MHz and 4.9 GHz of a new radio-selected galaxy cluster 1RXS J0603.3+4214 (z=0.225). The cluster is also detected

Evolution of galaxies in clusters [PDF]

Proceedings of Baryons in Dark Matter Halos — PoS(BDMH2004), 2004
I summarize what is know about the evolution of galaxies in clusters from the observational point of view presenting results at high (z~1), intermediate (z~0.5) and low (z~0) redshifts. I comment on the comparison between observations and predictions of CDM models, highlighting the observational landmarks more relevant for this comparison, such as the ...

From Fabrication to Failure—Aqueous Processing, Electrolyte Tuning, and Degradation Mechanism Elucidation in Poly(3‐Vinyl‐N‐Methylphenoxazine) Positive Electrodes

ChemSusChem, EarlyView.
Organic electrode materials are considered the next generation of battery electrode materials due to their environmental friendliness, low toxicity and competitive specific capacities. Herein, we report on a systematic study of processing of the redox polymer poly(3‐vinyl‐N‐methylphenoxazine) (PVMPO) using water processable binders, achieving ...

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.

X-ray observations of the galaxy cluster Abell 2029 to the virial radius [PDF]

, 2012
We present Suzaku observations of the galaxy cluster Abell 2029, which exploit Suzaku’s low particle background to probe the intracluster medium at radii beyond that which is possible with previous observations, and with better azimuthal coverage.

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Characterising galaxy clusters’ completeness function in Planck [PDF]

EPJ Web of Conferences
Galaxy cluster number counts are an important probe to constrain cosmological parameters. One of the main ingredients of the analysis is the selection function, and in particular the completeness, associated to the cluster sample one is considering ...

IDCS J1433.2+3306: AN INFRARED-SELECTED GALAXY CLUSTER AT z = 1.89 [PDF]

, 2012
We report the discovery of an IR-selected galaxy cluster in the IRAC Distant Cluster Survey (IDCS). New data from the Hubble Space Telescope spectroscopically confirm IDCS J1433.2+3306 at z = 1.89 with robust spectroscopic redshifts for seven members ...
