Ограничения На Особенности В Космологическом Спектре Мощности Из Наблюдений Эпохи Вторичной Ионизации

Key Points

• The central aim is to examine how varying power spectrum features influence the epoch of secondary ionization.
• Analysis of cosmological models with increased amplitude perturbations on dwarf galaxy scales.
• Comparison of early galaxy formation timings with standard power spectrum models.
• Investigation of redshift shifts due to varying power spectrum characteristics.
• Demonstrated that certain models can shift the secondary ionization epoch to higher redshifts.
• Showed that increased power spectrum amplitudes enhance early galaxy formation compared to standard models.
