ANN ARBOR—A comet-bound spacecraft that spent more than two years in a deep sleep mode woke up on Jan. 20 to begin the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice...
The contribution from blazar cascade emission to the extragalactic gamma-ray background: What a role does the extragalactic magnetic field play?
diffuse radiation galaxies active gamma rays general
2012/2/21
We estimate the contribution to the extragalactic gamma-ray background (EGRB) from both intrinsic and cascade emissions produced by blazars using a simple semi- analysis method for two models of the b...

We model the latest HST WFPC3/IR observations of > 100 galaxies at redshifts z=7-8 in terms of a hierarchical galaxy formation model with starburst activity. Our model provides a distribution of UV lu...

Some Doubts on the Validity of the Foreground Galactic Contribution
Cosmic microwave background—ISM clouds—dust extinction—ISM structure
2009/5/12
The Galactic foreground contamination inCMBRanisotropies,
especially from the dust component, is not easily separable from the cosmological
or extragalactic component. In this paper, some doubts wi...
