Dark matter is likely ‘cold,’ not ‘fuzzy,’ scientists report after new simulations（图）
Dark matter cold not fuzzy scientists new simulations
2017/7/24
Scientists have never directly detected dark matter. But over decades, they have proposed a variety of theories about what type of material — from new particles to primordial black holes — could compr...

We examine the velocity structure in the gas associated with \ion{H}{1} in the damped Ly$\alpha$ absorption system at redshift $z=1.7764$ towards the QSO $1331+170$ using 21cm data, optical and STIS s...
Large Scale Traces of Solar System Cold Dust on CMB Anisotropies
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Earth and Planetary Astrophysics (astro-ph.EP)

We explore the microwave anisotropies at large angular scales produced by the emission from cold and large dust grains, expected to exist in the outer parts of the Solar System, using a simple toy mod...
The spatial distribution of cold gas in hierarchical galaxy formation models
galaxy clustering
2010/2/26
The distribution of cold gas in dark matter haloes is driven by key processes in galaxy formation: gas cooling, galaxy mergers, star formation and reheating of gas by supernovae. We compare the predic...
