Milky Way-like Galaxies in Early Universe Embedded in 'Super Halos'
Milky Way-like Galaxies Early Universe Embedded Super Halos
2017/3/30
By harnessing the extreme sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only e...
Radio continuum observations of new radio halos and relics from the NVSS and WENSS surveys
Radio Continuum: galaxies – Galaxies: Clusters: general, intracluster medium – Cosmology: large-scale structure of Universe
2011/10/20
Radio halos and relics are diffuse radio sources found in galaxy clusters showing significant substructure at X-ray wavelengths. These sources provide important information about non-thermal processes...
Pairwise Velocities of Dark Matter Halos: a Test for the Lambda Cold Dark Matter Model using the Bullet Cluster
method : N-body simulations — galaxies : evolution — galaxies : for-mation — galaxies: clusters — cosmology : theory — cosmology : dark matter
2011/10/13
The existence of a bullet cluster (such as 1E0657-56) poses a challenge to the concordance Lambda cold dark matter model. Here we investigate the velocity distribution of dark matter halo pairs in lar...

Frozen Hydrocarbon Particles of Cometary Halos as Carriers of Unidentified Emissions
Comet ice luminescence frozen hydrocarbon particles unidentified lines
2009/5/12
The possible nature of unidentified cometary emissions is
under discussion.We propose a new model of the ice particles in cometary
halos as a mixture of frozen polycyclic aromatic hydrocarbons and a...
