Simulations of damped Ly alpha and Lyman limit absorbers in different cosmologies: Implications for structure formation at high redshift
formation large scale structure of the Universe
2014/12/26
We use hydrodynamic cosmological simulations to study damped Lyα (DLA) and Lyman limit (LL) absorption at redshifts z = 2-4 in five variants of the cold dark matter scenario: COBE-normalized (CCDM), c...
Using data from the Two Micron All Sky Survey, we identify a population of infrared carbon stars with J-KS ≥ 2 in the Milky Way. These stars are shown to trace the stellar bar previously identified in...
The fate of Cyg X-1: an empirical limit on BH-NS merger rate
Cyg X-1:empirical limit BH-NS merger rate
2011/10/12
The recent distance determination allowed precise estimation of the orbital parameters of Cyg X-1, which contains a massive 14.8 Msun BH with a 19.2 Msun O star companion. This system appears to be th...
Weak-field limit of Kaluza-Klein models with spherical compactification II: agreement with the observations
Weak-field limit Kaluza-Klein models spherical compactification agreement observations
2011/10/17
We investigate the classical gravitational tests for the Kaluza-Klein model with spherical (of a radius $a$) compactification of the internal space. The model contains also a bare cosmological constan...
