Session 10
- Chair: Anirban Chakraborty (NCRA)
We aim to investigate the influence on the 21cm brightness temperature for a non LCDM cosmology.The temperature dip,free electron fraction and the 21cm power spectrum is observed to change in the presence of a scalar field regime which shall be discussed throughout the talk.Alternatively a comparison with the JWST observation will also be made to investigate the contribution of the scalar field.
Recent observations with the James Webb Space Telescope (JWST) indicate a higher-than-expected abundance of galaxies at high redshifts (z > 10), potentially suggesting galaxy formation models with an enhanced star formation efficiency during the Cosmic Dawn (CD). These galaxy formation models are expected to leave their imprints on the thermal and ionization history of the intergalactic medium...
