In the last decade a large effort has been dedicated to detect one of the last phase transitions in the Universe called the Epoch of Reionization and its preceding epoch know as the Cosmic Dawn, specially with the redshifted 21 cm probe.
I will review the status of the various constraints that we currently have on reionization. I will also show the current results from a number operating telescopes in the 2 meter wavelength, a special attention will be paid to the recent results obtained with the LOFAR telescope. A discussion about the future of this effort will conclude my talk. |
