In what wavelength range do we detect the cmb
WebThe ground-based detectors LIGO, Virgo and GEO 600 (see [2–5] for recent status reports) are rapidly improving in sensitivity. The search of data from the last science run (LIGO S5, Virgo VSR1) of the initial versions of these detectors is still ongoing (see [6, 7] for upper limits on rates of low-mass binary mergers from the first part of the run). http://122.physics.ucdavis.edu/course/cosmology/sites/default/files/files/CMB/cmb_guide.pdf

WebAbstract. Far infrared cooling lines are ubiquitous features in the spectra of star forming galaxies. Surveys of redshifted fine-structure lines provide a promising new tool to study structure formation and galactic evolution at redshifts including the epoch of reionization as well as the peak of star formation.
