About the Fast Radio Burst Calculator

The Fast Radio Burst Calculator is a scientifically rigorous, peer-reviewed tool that instantly computes key astrophysical parameters of Fast Radio Burst events using the latest ΛCDM cosmology (Planck 2018 parameters). Designed for astronomers, students, and citizen scientists, this calculator delivers publication-ready results for luminosity distance, isotropic energy, peak luminosity, and cosmological redshift effects.

Scientific Foundation

All calculations follow standard formulas published in Nature, ApJ, and MNRAS:

Luminosity Distance D_L = (1+z) × D_C
Isotropic Energy E_iso = 4π D_L² × Fluence × Bandwidth (Δν)
Peak Luminosity L = E_iso / Duration

Key Features

Exact integration of comoving distance using Planck 2018 cosmology
Automatic DM to redshift estimation (NE2001 + Macquart relation)
Real-time calculation of rest-frame properties
Copy-paste ready numbers for papers and proposals

User Guidelines

Enter any known parameters (redshift, fluence, frequency, DM). Leave unknown fields blank or use defaults. The calculator will compute everything else instantly.

When to Use This Tool

Ideal for FRB papers, telescope proposals (CHIME, ASKAP, MeerKAT), student projects, and public outreach.

Importance of Fast Radio Bursts

Since the first discovery in 2007 by Duncan Lorimer, Fast Radio Bursts have revolutionized cosmology. They probe the “missing baryons,” test fundamental physics, and may soon become standard candles rivaling Type Ia supernovae.

Detailed Parameter Explanations

• Redshift (z): Cosmological stretching factor
• Fluence: Total energy received per unit area (Jy ms)
• Luminosity Distance: Distance accounting for expansion
• Isotropic Energy: Total energy if emitted uniformly in all directions (typically 10³⁸–10⁴⁴ erg)
