Cosmological Imprints of Pre-Inflationary Particles

Fialkov, Anastasia, Itzhaki, Nissan, Kovetz, Ely D.

Understand

We study some of the cosmological imprints of pre-inflationary particles.

We show that each such particle provides a seed for a spherically symmetric cosmic defect.
The profile of this cosmic defect is fixed and its magnitude is linear in a single parameter that is determined by the mass of the pre-inflationary particle.
We study the CMB and peculiar velocity imprints of this cosmic defect and suggest that it could explain some of the large scale cosmological anomalies.
