A new mechanism for primordial black hole formation during reheating
Luis E. Padilla, Juan Carlos Hidalgo, Karim A. Malik
The Reheating process at the end of inflation is often modeled by an oscillating scalar field which shows a background dust-like behaviour, prompting the analysis of gravitational…
Contributions from primordial non-Gaussianity and General Relativity to the galaxy power spectrum
Rebeca Martinez-Carrillo, Juan Carlos Hidalgo, Karim A. Malik +1
We compute the real space galaxy power spectrum, including the leading order effects of General Relativity and primordial non-Gaussianity from the and $g_{\mathrm…
The intrinsic bispectrum of the CMB from isocurvature initial conditions
Pedro Carrilho, Karim A. Malik
Non-linear effects in the early Universe generate non-zero bispectra of the cosmic microwave background (CMB) temperature and polarization, even in the absence of primordial non-Ga…
Galaxy number counts at second order in perturbation theory: a leading-order term comparison
Jorge L. Fuentes, Juan Carlos Hidalgo, Karim A. Malik
The galaxy number density is a key quantity to compare theoretical predictions to the observational data from current and future Large Scale Structure surveys. The precision demand…
Viable Gauge Choices in Cosmologies with Non-Linear Structures
Timothy Clifton, Christopher S. Gallagher, Sophia Goldberg +1
A variety of gauges are used in cosmological perturbation theory. These are often chosen in order to attribute physical properties to a particular choice of coordinates, or otherwi…
Relativistic and non-Gaussianity contributions to the one-loop power spectrum
Rebeca Martinez-Carrillo, Josue De-Santiago, Juan Carlos Hidalgo +1
We compute the one-loop density power spectrum including Newtonian and relativistic contributions, as well as the primordial non-Gaussianity contributions from and $g_…
