| 14:00 - 15:30 Weekly Seminar Observational Constraints on the Primordial Curvature Power Spectrum School ASTRONOMY Primordial power-spectrum can be tested using different sets of the observations and at different scales. At large scales, on the one hand, the combination of the CMB temperature fluctuations with that of the galaxy clusters and Lyman-alpha forest could be a good probe of the primordial power-spectrum. At small scales, on the other hand, primordial power-spectrum can be probed using the Primordial Black Holes (PBHs), Ultra Compact Mini Halos (UCMHs) and the CMB spectral distortion (SD). And, they could be complementary to the cosmological probe on the (relatively) large scales. In this talk, we consider the constraints by considering the seco ... |
