Distinguishing between Dark Energy Models
Houri Ziaeepour
Recent data and new data analysis methods show that most probably the parameter in the equation of state of the dark energy is smaller than -1 at low redshifts. We briefly revi…
Nonparametric determination of redshift evolution index of Dark Energy
Houri Ziaeepour
We propose a nonparametric method to determine the sign of γ- the redshift evolution index of dark energy. This is important for distinguishing between positive energy models, a co…
Quest for Fats: Roles for a Fat Dark Matter (WIMPZILLA)
Houri Ziaeepour
Since 1990's the detection of extremely energetic air showers and precise astronomical measurements have proved that our knowledge about fundamental laws of Nature is far from bein…
Solving Two Puzzles in One Go: Quintessence from a Decaying Dark Matter
Houri Ziaeepour
The mystery of the Dark energy is not just its smallness. The extreme fine tuning of its density in the Early Universe such that it permits galaxy formation before creating a new i…
Quintessence From a Decaying Dark Matter
Houri Ziaeepour
It is a known fact that a quintessence model with fits the publicly available Super Nova (SN) type Ia data better than a model with cosmological constant or .…
The XMM-Newton Bright Serendipitous Source Sample (XMM-Newton BSS)
R. Della Ceca, T. Maccacaro, A. Caccianiga +15
The XMM-Newton Survey Science Center is constructing a large (~1000 sources) and complete sample of bright serendipitous XMM-Newton sources at high galactic latitude, so as to allo…
