BINGO-2.0: BI-spectra and Non-Gaussianity Operator (The seco

Post by Dhiraj Kumar Hazra » October 02 2014

Dear all:

It is a pleasure to announce the second release of BI-spectra and non-Gaussianity Operator, BINGO-2.0. The description of the code can be found in both the websites provided below. You can use either of them to download the code.

1. http://www.physics.iitm.ac.in/~sriram/bingo/bingo.html

2. https://sites.google.com/site/codecosmo/bingo

Note that in case of the first mirror, due to some security certificate problem, sometimes the automated reply upon registration does not work for some e-mails. The second mirror is expected to work well. However, since the second mirror is relatively new, I would like to request you to write to me if you face any problem.

The following paper contains the results and analysis of BINGO-2.0.

"On the scalar consistency relation away from slow roll", V. Sreenath, Dhiraj Kumar Hazra, L. Sriramkumar, 1410.0252 [astro-ph.CO].

--------------------------------------------------------------------------------------------------

The history of the two versions and the changelog are as follows:
Version 2.0: October 2014

The bi-spectrum can be calculated for an arbitrary triangular configurations of the wavenumbers.

The bi-spectrum can be obtained in squeezed limit to, say, examine the consistency relation.

Python scripts have been included to create two-dimensional density plots and three-dimensional contour plots of bi-spectrum.

Added mpif90 option to run BINGO in multiple nodes.

Term = 0 calculates the total f_nl from all terms in the bi-spectrum.



Version 1.0: February 2013

The first release of BINGO.

The scalar bi-spectrum is evaluated in the equilateral configurations of wavenumbers.

It also includes calculations of the scalar power spectrum.

We welcome comments and suggestions on the code.

With Regards,

Dhiraj Hazra
