These clusters are probably young versions of globular clusters, but they are commonly called super star clusters. Seven dwarf galaxies within 16 million light-years have formed super star clusters, with one of these galaxies, NGC 1569, possessing two young clusters. ... Super star clusters have a lot to tell us about star formation. ...

... Ultraluminous X-ray sources (ULXs) are located in external galaxies, their X-ray luminosities (10 39 - 10 41 erg/s) are thousand times greater than those of brightest black holes in the Galaxy. ULXs may be supercritical accretion disks around black holes of stellar masses (~10 Solar masses) like that in SS433, or they may be a hypothetical intermediate-mass black holes (hundreds - thousands Solar masses) with standard accretion disks. ... 2) The ULX progenitors were ejected from the star clusters. ...

... Astrophysics Group . ... AMI Science . ... Observations of galaxy clusters are central to the AMI science programme. The AMI Small Array is used to observe already-known clusters with high-sensitivity and resolution, allowing us to extract detailed information about individual clusters and to build up statistics about the cluster population. ... Observing galaxy clusters at 15 GHz is tricky because of the contamination from foreground radio sources, which is where the Large Array comes in! ...

... On exposures affected by it, the warning InvalidObtValue is generated during the processing. This will be fixed with a software update, available in future SAS versions. ... If this problem occurs, you should process the affected pn exposures with SAS versions older than v6.0.0 (indeed, it is enough to run the SAS v5.4.1 epframes , and then, for instance, re-use the output files in a subsequent epchain run, specifying the parameter runepframes=N ).

... We found that 10 metal-poor globular clusters are greately distinguished for anomalously small masses on the "destruction rate-mass" plain. As it turned out, these poor clusters, situated 15 kpc farther from the Galactic centre, are somewhat younger than the bulk of the metal-poor globulars, and have anomalously red horizontal branches. ... At the same time, deficiency of distant massive clusters is noticeable with increasing distance from the galactic centre. ...

... Magnetic compass discovered in China . ... Richard Carrington in England observes a violent and rapid eruption near a sunspot; 17 hours later a large magnetic storm begins. ... The electrons hit near the magnetic poles, leading him to propose that the polar aurora is created by electron beams from the Sun. ... Syun-Ichi Akasofu (Japan-US) and Sydney Chapman revive and expand Birkeland's notion of a "polar magnetic storm", now named "magnetospheric substorm." ...

... Tidal circularisation of white dwarfs and formation of sources of gravitational waves in globular clusters . ... I point out that a major fraction of white dwarfs tidally captured by the black hole may be destroyed by tidal inflation and rotational break-up during ongoing tidal circularisation, and therefore the formation of tight binaries is inhibited. However, some fraction may survive tidal circularisation through being spun up to high rotation rates where tidal interactions are less effetive. ...

... We report on the preliminary results of experiments using a Bayesian cluster method to cluster objects present in photographic images of the POSS-II. ... We believe that the application of such algorithms to large-scale astronomical sky surveys can aid in cataloging the detected objects, and may even have the potential to discover new categories of objects. ... We have thus started to explore new clustering analysis and unsupervised classification techniques for this task. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

... V79 was known as an RRab type star or fundamental mode pulsator with the period of about 0.483 day during the century after its discovery by S.I.Bailey in 1895. ... The first overtone with the period of 0.359 day became the dominant mode. ... Periodogram analysis gives the only period of 0.4825 day, but not of 0.359 day. ... The period of this modulation is unusually small and equal to 1.389 day, that suggests the beat period or resonance motion between the fundamental mode and the first overtone. ...
