Cosmic Strings and Structure Formation
We discuss structure formation in cosmic string theories. Emphasis is laid on the properties of the peculiar velocity field, non–gaussian features and clusters of galaxies. It is found that the predicted peculiar velocity field is quiet (v < 150 km/s for L > 30h Mpc) for models with (Ω0h ≤ 0.2) which is in disagreement with the results from POTENT at large scales (> 30h Mpc), consistent, howeve...
متن کاملGalaxy formation spanning cosmic history
Over the past several decades, galaxy formation theory has met with significant successes. In order to test current theories thoroughly we require predictions for as yet unprobed regimes. To this end, we describe a new implementation of the GALFORM semi-analytic model of galaxy formation. Our motivation is the success of the model described by Bower et al. in explaining many aspects of galaxy f...
متن کاملMicrolensing by cosmic strings
We consider the signature and detectability of gravitational microlensing of distant quasars by cosmic strings. Because of the simple image configuration such events will have a characteristic lightcurve, in which a source would appear to brighten by exactly a factor of 2, before reverting to its original apparent brightness. We calculate the optical depth and event rate, and conclude that curr...
متن کاملFormation of primordial black holes by cosmic strings.
We show that in a pioneering paper by Polnarev and Zembowicz, some conclusions concerning the characteristics of the Turok-strings are generally not correct. In addition we show that the probability of string collapse given there, is off by a large prefactor (∼ 103). ∗Electronic address: [email protected] †Electronic address: [email protected] ‡Electronic address: [email protected]
متن کاملFormation of Wakes by Chiral Conducting Cosmic Strings
Topological defects are predicted in many gauge models as solitonic solutions resulting from spontaneous breaking of gauge or global symmetries. Among all these solutions, cosmic strings, and in particular those with conducting properties, have a number of cosmological applications.1 The possible scenarios for structure formation by cosmic strings depend very much in the detail of the model. On...
