We consider the detection of cosmic strings using observations of the anisotropy of the Cosmic Microwave Background. Several methods for detecting cosmic strings are analyzed, using a threshold filter and expansion in orthogonal Haar functions. Computer simulation provides estimates of the noise present in experiments aimed at detection of cosmic strings. Attempts to detect cosmic strings were carried out using the full-sky ILC map obtained as a result of the WMAP space mission. A list of cosmic string candidates has been compiled using the Haar function method. 相似文献

Binary stars are considered as possible sources of monochromatic gravitational waves. The amplitude of corrections to the metric generated by such sources is discussed. Three systems that have amplitudes for stresses of the metric exceeding 10?20 are identified (V1182 Aql, V3903 Sgr, and DH Cep). 相似文献

We have obtained an analytical solution to the problem of determining the initial elevation at the tsunami source, which was formed by small residual deformations of a flat sloping bottom. This solution, which is newly derived, is compared with the known analytical solution of an equivalent problem over a horizontal bottom. It is shown that applying an analytical solution over a horizontal bottom for calculating the initial perturbations in the sources of realistic tsunami provides sufficient accuracy. 相似文献

The conference “Modern Astrometry 2017,” which took place on Octobr 23–25, 2017 at the Sternberg Astronomical Institute of Lomonosov Moscow State University, was dedicated to the memory of the eminent astrometrist, teacher, and outstanding scientist and Doctor of Physical–Mathematical Siences Konstantin Vladslavovich Kuimov, who worked at the Sternberg Astronomical Institute during 1962–2017. This article is based on a presentation made at this conference. 相似文献
