Abstract: The intrinsic peak luminosity of Type Ia supernovae (SNIa) depends on the value of Newton's gravitational constant G, through the Chandrasekhar mass MCh∝ G−3/2. If the luminosity distance can be independently determined, the SNIa can… read more here.

DOI: 10.1088/1475-7516/2019/07/037
Abstract: We consider two stable Interacting Dark Matter -- Dark Energy models and confront them against current Cosmic Microwave Background data from the \textit{Planck} satellite. We then generate luminosity distance measurements from ${\cal O}(10^3)$ mock Gravitational… read more here.

Abstract: Standard sirens are the gravitational wave (GW) analog of the astronomical standard candles, and can provide powerful information about the dynamics of the Universe. In this work, we simulate a catalog with 1000 standard siren… read more here.
