| Towards detection of radio signatures of cosmic dawn |
| by Ravi Subrahmanyan (Raman Research Institute) |
| Abstract: As first light from the first stars transforms the universe from the dark ages into cosmic dawn, the history may be traced in redshifted 21-cm from neutral hydrogen in the gas. Efforts to build precision radiometers over the 40-200 MHz band to detect this faint signal are beginning to yield results of significance to the theory, thus constraining the starlight of the earliest galaxies. I will review the field and discuss the problems and progress. |
