... The Role of Feedback and Dark Matter on the Evolution of Dwarf Galaxies . ... Our approach follows naturally from the evidence that supernova explosions (SNe) and superbubbles (SB) are the main contributors to the galaxy energy budget, and are easily able to regulate the its metal content. ... On this basis, we predict the correlations between overall properties of the galaxy like metallicity, dark matter content, gas mass and velocity dispersion. ...

... Ever wonder how solar-mass stars form?. ... In order for material to accrete onto a protostar it has to lose angular momentum. The angular momentum of a large natal cloud leads to the formation of a circumstellar disk and inner accretion disk as the cloud collapses. ... Winds generated in the inner disk or close to the stellar surface (we don't know which) expel material along the disk rotation axis. ... This provides the highest resolution observational data on nearby young stars. ...

... They cover a period of 4 days in which the Supernova continues to rise in brightness (what astronomers call magntiude). ... First Image Taken on March 11 at 8:22 UT. Second Image Taken on March 12 at 8:52 UT. ... The supernova is the same brightness as in the previous image taken 2 hours ago . ... This image, taken 24 hours after the previous image, shows the supernova to be another 0.21mag (or about 25%) brighter. ... Hopefully the images do show that the brightness of the Supernova is changing. ...

Detection technique . We are using ISIS , the optimal image subtraction method developed by C. Alard & R.H. Lupton, to search for SNe in our images. ... The second image shows the same subtraction, but after the convolution of the best image with ISIS: . ... For this reason, we are suggested to search for nuclear SNe with NICMOS on HST, to exploit its stable PSF, sensitivity and angular resolution to detect from space nuclear obscured SNe which might have been missed by ground-based surveys. ...

ChASeM33 . The Chandra ACIS Survey of M33 - . ... The major sources of feedback into the ISM are massive OB stars, which inject energy via Lyman continuum photons, stellar winds and, finally, supernova explosions. ... SB interiors are generally more efficient than individual SNRs in converting thermal into kinetic energy of expansion, because radiative losses are smaller in SBs than for the same number of isolated explosions. ... 1) Is the diffuse hot ISM shaped predominantly by SNRs or by SBs? ...

To locate it, look along the imaginary line between the two end stars on the leading edge of the PloughтАЩs blade (Merak and Dubhe) and Polaris (the North Star), the galaxy M82 (also known as the Cigar Galaxy) along with its companion M81, lies just off this line about a third of the way between the Plough and Polaris. €а€аAs usual, the supernova is far brighter than its home galaxy, appearing as an extra star. ...

Next: Fringe correction Up: Special Processing Options Previous: Sky Illumination Corrected . A third method to account for illumination problems in the flat fields is to remove the large scale pattern from the flat field itself. This is useful if there are no reasonable blank sky calibration frames and the astronomical exposures are evenly illuminated but the flat fields are not. This is done by smoothing the flat field frames instead of blank sky frames. ...
