Galaxy cluster formation from the large-scale structure: a case study of the Abell 2125 complex at z=0.247
C153 SW cD
2014/12/24
The structure of the universe is believed to have formed by clustering hierarchically from small to large scales. Much of this evolution occurs very slowly but at a few special times more rapid, viole...
Large-scale structure of the molecular gas in Taurus revealed by high linear dynamic range spectral line mapping
molecules structure
2014/12/23
We report the results of a 100 deg2 survey of the Taurus molecular cloud region in 12CO and 13CO J = 1→ 0. The image of the cloud in each velocity channel includes 3 × 106 Nyquist-sampled pixels on a ...
AzTEC Millimetre Survey of the COSMOS field - II. Source count overdensity and correlations with large-scale structure
galaxies submillimeter gravitational lensing
2014/12/22
We report an overdensity of bright submillimetre galaxies (SMGs) in the 0.15 deg2 AzTEC/COSMOS survey and a spatial correlation between the SMGs and the optical-IR galaxy density at z≲ 1.1. This...
Isocurvature modes and Baryon Acoustic Oscillations II: gains from combining CMB and Large Scale Structure
Baryon Acoustic Oscillations combining CMB Large Scale Structure
2011/9/29
We consider cosmological parameters estimation in the presence of a non-zero isocurvature contribution in the primordial perturbations. A previous analysis showed that even a tiny amount of isocurvatu...
