Primordial non-Gaussianity, scale-dependent bias, and the bispectrum of galaxies
Donghui Jeong, Eiichiro Komatsu
We calculate the bispectrum, B_g(k_1,k_2,k_3), Fourier transform of the three-point function of density peaks (e.g., galaxies), using two different methods: the Matarrese-Lucchin-B…
Infrared divergence of pure Einstein gravity contributions to cosmological density power spectrum
Hyerim Noh, Donghui Jeong, Jai-chan Hwang
We probe the pure Einstein's gravity contributions to the second-order density power spectrum. In the small-scale, we discover that the Einstein's gravity contribution is negligibl…
Perturbation Theory Reloaded II: Non-linear Bias, Baryon Acoustic Oscillations and Millennium Simulation In Real Space
Donghui Jeong, Eiichiro Komatsu
We calculate the non-linear galaxy power spectrum in real space, including non-linear distortion of the Baryon Acoustic Oscillations, using the standard 3rd-order perturbation theo…
Modular Cosmology, Thermal Inflation, Baryogenesis and Predictions for Particle Accelerators
Donghui Jeong, Kenji Kadota, Wan-Il Park +1
Modular cosmology is plagued by overproduction of unwanted relics, gravitinos and especially moduli, at relatively low energy scales. Thermal inflation provides a compelling soluti…
