In this study, Riess and his SH0ES (Supernovae, H0, for the Equation of State) Team analyzed light from 70 stars in our neighboring galaxy, the Large Magellanic Cloud, with a new method that allowed for capturing quick images of these stars.
The enhanced capabilities afforded by ALIGO+ are expected to illuminate the origins and evolution of stellar-mass black holes, allow precision tests of extreme gravity, enable detailed study of the equation of state of neutron stars, and permit new tests of cosmology, including fully independent constraints on the Hubble constant.
Using this effective potential and by incorporating quasi-particle Debye mass, we have then developed the equation of state for strongly interacting matter and have shown our results on pressure, energy density, and speed of sound along with the lattice data.
