Astrophysicists from Johns Hopkins University have proposed a clever new way of shedding light on the mysterious dark matter believed to make up most of the universe. The irony is they want to try to ...
Stellar parenting:Making new stars by 'adopting' stray cosmic gases
Stellar parenting Making new stars adopting stray cosmic gases
2016/1/27
Among the most striking objects in the universe are glittering, dense swarms of stars known as globular clusters. Astronomers had long thought globular clusters formed their millions of stars in bulk ...
Halo based reconstruction of the cosmic mass density field
galaxies: haloes – groups: general– cosmology: dark matter – large-scale structure of Universe – methods: numerical
2011/7/6
We present the implementation of a halo based method for the reconstruction of the cosmic mass density field. The method employs the mass density distribution of dark matter haloes and its environment...
Formation & evolution of cosmic superstrings: a short review
cosmic superstrings cosmic strings brane inflation M-theory
2010/1/11
I will briefly review the formation and evolution of cosmic superstrings, in the context of brane-world cosmological models within M-theory. These objects can play the role of cosmic strings, offering...
Cosmologies with running cosmological term (Lambda) and gravitational Newton's coupling (G) may naturally be expected if the evolution of the universe can ultimately be derived from the first principl...

Forbush decrease of the galactic cosmic ray intensity：experimental study and theoretical modeling
cosmic ray intensity theoretical modeling
2009/5/27
We study the temporal changes of the power law rigidity spectrum of the Forbush decrease (Fd) of the galactic cosmic ray (GCR) intensity. We show that the power law rigidity spectrum of Fd for the pe...
27-day variations of the galactic cosmic ray intensity and anisotropy
cosmic ray intensity 27-day variations
2009/5/27
We study the 27-day variations of the galactic cosmic ray (GCR) intensity and three dimensional (3-D) anisotropy in different polarity periods of the solar magnetic cycle. We found that the larger am...

Long-term Modulation of Cosmic Ray Intensity in relation to Sunspot Numbers and Tilt Angle
Cosmic ray intensity sunspot numbers tilt angle
2006/10/30
Adetailed correlative analysis between sunspot numbers (SSN)and tilt angle (TA) with cosmic ray intensity (CRI) in the neutron monitor energy range has been performed for the solar cycles 21, 22 and 2...
Exact Solutions of Brans-Dicke Cosmology and the Cosmic Coincidence Problem
Brans-Dicke Cosmology the Cosmic Coincidence Problem
2005/12/31
We present some cosmological solutions of Brans-Dicke theory, characterized by a decaying vacuum energy density and by a constant relative matter density. With these features, they shed light on the c...
