BINGO: BI-spectra and Non-Gaussianity Operator

[Dhiraj Kumar Hazra]

Dear All:

It is our pleasure to announce that, we are making the code BI-spectra and Non-Gaussianity Operator, or simply BINGO, publicly available.

BINGO is a Fortran 90 code that numerically evaluates the scalar bi-spectrum and the non-Gaussianity parameter fNL in single field inflationary models involving the canonical scalar field. The code is based on the Maldacena formalism to evaluate the bi-spectrum. The code can evaluate all the contributions to the scalar bi-spectrum and the non-Gaussianity parameter fNL for an arbitrary triangular configuration of the wavevectors.

We have made a limited version of the code, viz. one that focuses on the equilateral limit, available online at the following URL:

The methods and the numerical procedures that BINGO adopts are described in detail in the following paper: D. K. Hazra, L. Sriramkumar and
J. Martin, 1201.0926 [astro-ph.CO].

We welcome comments and suggestions on the code.

Thanking you,

With Regards,

Dhiraj Hazra.
