... Most stars form in clusters, so the simple picture of star formation needs to incorporate the impact that young stars have on their environments, and each other. One region we study is NGC 1333, shown to the left as seen by the Spitzer Space Telescope.

A few percent of the total flux from this brightest region in Henize 206 emanates from infrared peaks of subparsec scale. ...

... GSAOI Home . ... Science . ... Deep imaging at J , H , and K is required to identify all stellar objects, brown dwarfs, and planetary mass objects in the central region of the Orion Nebula Cluster down to masses comparable to that of Jupiter. This is required to establish the initial mass function, i.e., the number of stars of each mass that have formed, in this region of intense massive star formation. ... The fields of the GSAOI detectors are shown as four green squares in each frame. ...

... We report on our ongoing project ``Infrared Study of HII Regions Associated with Small Clouds.' ... These IR data, combined with optical imaging (which will be obtained from the IAC-80 telescope), IRAS survey maps, and existing CO observations of the associated clouds, will allow us to undertake a detailed investigation of the gas-to-dust mass ratio, initial mass function and the star-formation efficiency in these complexes. ...

Dense regions reach a maximum size and then fall back into a bound object like a cluster of galaxies. Once the cluster is formed, its physical size remains essentially constant. The space-time diagram below . shows a dense region in blue on the left. ... The galaxies in the blue region are accelerating more just because the region is denser and therefore has higher gravitational forces. ... Tutorial : Part 1 | Part 2 | ...

... Cancellation occurs. ... The cancellation in this small region exists until 08:00 when all the negative fragments disappeared, but rarely see any X-ray response. 02:30 Many small positive fragments emerge at south. Then they become stronger and move toward the preexisting positive ones to form a bigger one. A cluster of negative fragments with some weak positive ones nearby present at the south. ... Some other negative fragments moving from north of the positive one start to take action. ...

... The large field size of UIT is ideal for studies of globular clusters. ... Very metal poor clusters are conducive for the formation of very hot horizontal branch stars which radiate most of that energy in the UV part of the spectrum. ... M31 is the nearest large spiral galaxy to us. ... These are small dwarf galaxies and NGC 205 is a bit unusual because it still has retained some gas for star formation despite its low mass. M33 is an actively star forming spiral galaxy in the local group. ...

... Meta Index / Home Page / Description / Specifying source region shapes . When radiusstyle =`contour', the task calculates the source region shape as an elliptical locus which approximates the contour of the PSF at a given flux value. ... Clearly, in order to calculate the shape of such a flux contour, it is necessary firstly to normalize the PSF to the source brightness and secondly to determine the flux level (in `brightness' units per pixel) at which to find the contour. ...

However others are less pessimistic and it has even been claimed that the mysterious ?Wow! signal? received in 1977 originated from the direction M55.б  Sadly, this still unexplained pulse of radio energy originated from a location rather to the northwest of M55 so I doubt if the source was this cluster (if indeed the signal was genuinely of extraterrestrial origin). ...

. The seminar is supported by the grant of Federal Programm "Integration" . annotation of talk . Yu.N.Efremov "GRBs and triggered star formation" . Evidences are presented that giant arcs of young stars and clusters are formed in the gas swepted-up by GRBs near their centres. Multiple arcs suggested that the source of GRBs progenitors is in the same region, this must be old massive cluster. The candidate cluster for the arcs in the LMC is suggested.

... The dayside auroral precipitation consist of magnetosheath related boundary layer precipitation, and plasma sheet related BPS/CPS precipitation (extensions of the nightside precipitation regions). ... For example, the much lower fluxes from the LLBL region when compared to the cusp are compensated by the bidirectional electron beams found in the LLBL: the precipitating energy fluxes in the LLBL and the cusp are not that different. ... directly through the cusp and plasma mantle . ...
