Cosmic Explosions (Optical)
One of the principal motivations of wide-field and synoptic surveys is the search for, and study of, transients. By transients I mean those sources that arise from the background, are detectable for some time, and then fade away to oblivion. Transients in distant galaxies need to be sufficiently bright as to be detectable, and in almost all cases those transients are catastrophic events, markin...

متن کاملCosmic Explosions: Rapporteur Summary of the 10th Maryland Astrophysics Conference
This meeting covered the range of cosmic explosions from solar flares to γray bursts. A common theme is the role of rotation and magnetic fields. New information from the Sun shows that a “magnetic carpet” contains most of the surface field that feeds the corona. Disk instabilities in protostellar disks may provide most of the growth of a protostar. Type Ia supernovae continue to give evidence ...
متن کاملLimits on the detectability of cosmic topology in hyperbolic universes
We reexamine the possibility of the detection of the cosmic topology in nearly flat hyperbolic Friedmann-Lemâıtre-Robertson-Walker (FLRW) universes by using patterns repetition. We update and extend our recent results in two important ways: by employing recent observational constraints on the cosmological density parameters as well as the recent mathematical results concerning small hyperbolic ...
متن کاملThe First Supernova Explosions in the Universe
We investigate the supernova explosions that end the lives of massive Population III stars in low-mass minihalos (M ∼ 10M⊙) at redshifts z ∼ 20. Employing the smoothed particle hydrodynamics method, we carry out numerical simulations in a cosmological set-up of pair-instability supernovae with explosion energies of ESN = 10 51 and 10 ergs. We find that the more energetic explosion leads to the ...
