The Atacama Cosmology Telescope: Physical Properties and Purity of a Galaxy Cluster Sample Selected via the Sunyaev-Zel'dovich Effect
(2010)
We present optical and X-ray properties for the first confirmed galaxy cluster sample selected by the Sunyaev-Zel'dovich Effect from 148 GHz maps over 455 square degrees of sky made with the Atacama Cosmology Telescope. ...
Cluster Ages Experiment (CASE): deficiency of observed dwarf novae in globular clusters
(2008)
We present the results of a search for dwarf novae (DNe) in globular clusters (GCs). It is based on the largest available homogeneous sample of observations, in terms of the time span, number of observations and number of ...
The effective sample size for multivariate spatial processes with an application to soil contamination
(2021)
Effective sample size accounts for the equivalent number of independent observations contained in a sample of correlated data. This notion has been widely studied in the context of univariate spatial variables. In that ...
Low X-Ray Luminosity Galaxy Clusters. IV. SDSS galaxy clusters at z < 0.2
(Wiley Blackwell Publishing, Inc, 2019-06)
This is the fourth of a series of papers on low X-ray luminosity galaxy clusters. The sample comprises 45 galaxy clusters with X-ray luminosities fainter than 0.7 × 1044 erg s.1 at redshifts lower than 0.2 in the regions ...
A sample of relatively unstudied star clusters in the Large Magellanic Cloud: fundamental parameters determined from Washington photometry
(EDP Sciences, 2013-07)
Aims. To enlarge our growing sample of well-studied star clusters in the Large Magellanic Cloud (LMC), we present CCD Washington CT1 photometry to T1 ∼ 23 in the fields of twenty-three mostly unstudied clusters located in ...
Different clusters in patients with chronic obstructive pulmonary disease (Copd): A two-center study in brazil
(2020-01-01)
Background: Chronic obstructive pulmonary disease (COPD) has a functional definition. However, differences in clinical characteristics and systemic manifestations make COPD a heterogeneous disease and some manifestations ...
Imaging of star clusters in unperturbed spiral galaxies with the Advanced Camera for Surveys. II. A comparison of star cluster systems in five late type spirals
(2009)
Aims. Our goal is to investigate the formation of star clusters in relatively unperturbed environments. To do this, we studied the five nearby spiral galaxies: NGC 45, NGC 1313, NGC 4395, NGC 5236, and NGC 7793. Methods. ...
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 ...
On the formatión epoch of cluster galaxies and the growth of the red-sequence from a sample of rich clusters at z - 1.
(2009)
Galaxy clusters, the most massive virialized structures in the Universe, are ideal systems to study the formation and evolution of galaxies in high density environments.
Their cores are dominated by early-type galaxies, ...
Open clusters: III. Fundamental parameters of B stars in NGC 6087, NGC 6250, NGC 6383 and NGC 6530. B type stars with circumstellar envelopes.
(EDP Sciences, 2018-02)
Context. Stellar physical properties of star clusters are poorly known and the cluster parameters are often quite uncertain.Aims. Our goals are to perform a spectrophotometric study of the B star population in open clusters ...
