astronomR: Cosmic Insights: Statistical Frameworks for Astronomers
A comprehensive toolkit for astronomical and cosmological
computations. Provides functions for angular coordinate conversions
(degrees, hours-minutes-seconds, degrees-minutes-seconds, and radians),
Julian Days and the conversion of equatorial (right ascension,
declination) to horizontal (altitude, azimuth) coordinates, access to
fundamental physical constants ('CODATA' 2018), queries to the Gaia
Catalogue of Nearby Stars through the Gaia Archive TAP (Table Access
Protocol) service, a 'Lambda-CDM' cosmology model with comoving,
luminosity and angular-diameter distances, cosmic time and the age of the
universe, early-universe thermal physics including photon density, 'Saha' equation
solutions, and a full thermal-cosmology module covering the Hubble rate in
the radiation-dominated era, effective relativistic degrees of freedom,
entropy density, equilibrium yields, the Boltzmann relic-abundance
('pebble') equation for WIMP freeze-out, the freeze-out temperature solver,
and the Peebles equation for hydrogen recombination. Also includes the
Drake equation for estimating the number of communicating extraterrestrial
civilisations in the Milky Way.
