Open clusters in the third galactic quadrant - II. The intermediate age open clusters NGC 2425 and NGC 2635
(EDP SCIENCES, 2006-01)
We analyse CCD broad band (UBV(RI)(C)) photometric data obtained in the fields of the poorly studied open clusters NGC 2425 and NGC 2635. Both clusters are found to be of intermediate age thus increasing the population of ...
Big bang methodology applied to atomic clusters
(2011)
An implementation of a novel strategy for cluster geometry optimization, using a stochastic method, is applied. This algorithm is based on the spirit of Big Bang theory. The strategy consists on a three-step procedure; a ...
Electronic properties of small bimetallic LinCum (n, m ≤ 4) clusters. A comparison with Lin and Cun clusters
(2005)
The electronic structure and geometry of clusters of the type Li nCum, LinCum+1 (n, m ≤ 4), Lin, and Cun (n ≤ 8) were theoretically investigated using density functional methods. The LinCum bimetallic system is important ...
On the role of PES data in the identification of metal-metal charge transfer bands in clusters of clusters
(Elsevier Science Publ. B.V., 1993)
The clusters of M2[O2CCCo3(CO)9]4-n[O2CR]n, where M is Cr, n= O; where M is Mo, n = 0,1, R is CH3; where M is W, n=0; exhibit allowed transitions with absorvance maxima that correlate with the lowest ionization energy of ...
Signatures of galaxy-cluster interactions: Spiral galaxy rotation curve asymmetry, shape, and extent
(UNIV CHICAGO PRESS, 2001-04)
The environmental dependencies of the characteristics of spiral galaxy rotation curves are studied in this work. We use our large, homogeneously collected sample of 510 cluster spiral galaxy rotation curves to test the ...
A Rough-Fuzzy approach for Support Vector Clustering
(Elsevier, 2016)
Support Vector Clustering (SVC) is an important density-based clustering algorithm which can be applied in many real world applications given its ability to handle arbitrary cluster silhouettes and detect the number of ...
Effect of mitochondrial complex I inhibition on Fe-S cluster protein activity
(2011)
Iron-sulfur (Fe-S) clusters are small inorganic cofactors formed by tetrahedral coordination of iron atoms with sulfur groups. Present in numerous proteins, these clusters are involved in key biological processes such as ...
Strong lensing in the inner halo of galaxy clusters
(Oxford Univ. Press, 2016)
We present an axially symmetric formula to calculate the probability of finding gravitational arcs in galaxy clusters, being induced by their massive dark matter haloes, as a function of clusters redshifts and virial masses. ...
A 3D Voronoi+Gapper Galaxy Cluster Finder in Redshift Space to z ∼ 0.2. II. An Abundant Cluster Population Dominated by Late-type Galaxies Unveiled
(IOP, 2020)
We identify 1901 galaxy clusters (N-g >= 2) with the VoML+G algorithm (Paper I) on the Two-Degree Field Galaxy Redshift Survey. We present the 341 clusters with at least 10 galaxies that are within 0.009 < z < 0.14 (the ...
Ferromagnetic bond of Li-10 cluster: An alternative approach in terms of effective ferromagnetic sites
(2016)
In this work, a model to explain the unusual stability of atomic lithium clusters in their highest spin multiplicity is presented and used to describe the ferromagnetic bonding of high-spin Li-10 and Li-8 clusters. The ...
