Dark Matter: The evidence from astronomy, astrophysics and cosmology

, 2010
Dark matter has been introduced to explain many independent gravitational effects at different astronomical scales, in galaxies, groups of galaxies, clusters, superclusters and even across the full horizon. This review describes the accumulated astronomical, astrophysical, and cosmological evidence for dark matter.

ISENTROPIC "SHOCK WAVES" IN NUMERICAL ASTROPHYSICS

Odessa Astronomical Publications, 2016
Numerical simulations of the cold supersonic flows in different astrophysical problems meets with the loss of precision difficulty. For to overcome the difficulty it was suggested earlier to use conservation entropy equation instead of energy ...

Search for double beta decay of 136Xe to the 0 1 + $$ {0}_1^{+} $$ excited state of 136Ba with PandaX-4T

Journal of High Energy Physics
We perform a search of double beta decay of 136Xe to the excited state, 0 1 + $$ {0}_1^{+} $$ , of 136Ba (2νββ- 0 1 + $$ {0}_1^{+} $$ ), using the dual-phase xenon detector of PandaX-4T with the first 94.9-day commissioning data.

Investigating Long-Term Behaviour of X-ray Binaries Using Archival Data

Acta Polytechnica CTU Proceedings, 2015
Long term modulations have been detected in a wide variety of both low and high-mass X-ray binaries. The All Sky Monitor on board the Rossi X-ray Timing Explorer provides the most extensive (~15 years) and sensitive X-ray archive for studying such ...
