A catalogue of 74 new open clusters found in Gaia Data-Release 2

نویسندگان

چکیده

Based on astrometric data from Gaia DR2, we employ an unsupervised machine learning method to blindly search for open star clusters in the Milky Way within Galactic latitude range of |b| < 20 degrees. In addition 2,080 known clusters, 74 new cluster candidates are found. this work, present positions, apparent radii, parallaxes, proper motions and member stars these (https://cdsarc.u-strasbg.fr/ftp/vizier.submit//new_OC/). Meanwhile, obtain physical parameters each candidate cluster, stellar isochrones fit photometric data. The results show that radii observed motion dispersions consistent with those previously identified DR2.

Parallaxes and proper motions for 20 open clusters as based on the new Hipparcos catalogue

Context. A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming that the accuracies for nearly all stars brighter than magnitude Hp = 8 are improved, by up to a factor 4, compared to the original catalogue. As correlations between the underlying abscissa residuals have also been reduced by more than an order of magnitude to an insignificant lev...

Testing the significance of clusters found in gene expression data

A challenge in bioinformatics is the identification of coexpressed genes or particular types of tissue based on microarray data. The most prominent approach for this task is cluster analysis. It has been increasingly applied to gene expression data sets during the last few years. However, bioscientists who consider clustering as potentially useful for their studies, have the problem that the ob...

WINGS Data Release: a database of galaxies in nearby clusters

Context. To effectively investigate galaxy formation and evolution, it is of paramount importance to exploit homogeneous data for large samples of galaxies in different environments. Aims. The WINGS (WIde-field Nearby Galaxy-cluster Survey) project aim is to evaluate physical properties of galaxies in a complete sample of low redshift clusters to be used as reference sample for evolutionary stu...
