Cosmic Mach Number as a Function of Overdensity and Galaxy Age
We carry out an extensive study of the cosmic Mach number (M) on scales of R = 5, 10 and 20hMpc using a LCDM hydrodynamical simulation. We particularly put emphasis on the environmental dependence of M on overdensity, galaxy mass, and galaxy age. We start by discussing the difference in the resulting M according to different definitions of M and different methods of calculation. The simulated M...
متن کاملCalculation of nuclear level density parameter as a function of tmperature and mass number
Nuclear level density is one of the most important concepts in nuclear physics; basically, it is the key in dealing with nuclear statistical problems. This quantity plays an essential role in the statistical calculation of reactor physics, astrophysics, researches in the average energy of heavy- ion collision and calculations related to neutron evaporation and other applications. This quantity ...
متن کاملGamma-ray Bursts as a Cosmic Window for Galaxy Evolution
Present knowledge indicates that gamma-ray bursts are linked with massive stars. They will become invaluable probes of the early universe and galaxy formation. In the future, it will be possible to use gamma-ray bursts for two purposes: 1) to probe the history of massive star formation in the Universe by the rate of occurence of gamma-ray bursts, and 2) for the study of galaxy evolution at all ...
متن کاملa fundamental study of "histiriographic metafiction", and "literary genres", as introduced in "new historical philosophy", and tracing them in the works of julian barnes.
abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
15 صفحه اولSeparating cosmic shear from intrinsic galaxy alignments: correlation function tomography
During the past couple of years, secure detections of cosmic shear have been obtained, manifest in the correlation of the observed ellipticities of galaxies. Constraints have already been placed on cosmological parameters, such as the normalisation of the matter power spectrum σ8. One possible systematic contaminant of the lensing correlation signal arises from intrinsic galaxy alignment, which...
