Late-time Cosmology without Dark Sector but with Closed String Massless Sector
Hocheol Lee, Jeong-Hyuck Park, Liliana Velasco-Sevilla +1
We explore the possibility of solving the dark energy and the coincidence problems by postulating the massless sector of closed strings. This sector constitutes the gravitational m…
Cosmic-Dawn 21-cm Signal from Dynamical Dark Energy
Lu Yin
The 21-cm signal is the most important measurement for us to understand physics during cosmic dawn. It is the key for us to understand the expansion history of the Universe and the…
Is Cosmic Birefringence model-dependent?
Lu Yin, Joby Kochappan, Tuhin Ghosh +1
Exciting clues to isotropic cosmic birefringence have recently been detected in the cross-power spectra of the polarization data of the cosmic microwave background (CMB). Earl…
WIMPs in Dilatonic Einstein Gauss-Bonnet Cosmology
Anirban Biswas, Arpan Kar, Bum-Hoon Lee +5
We use the Weakly Interacting Massive Particle (WIMP) thermal decoupling scenario to probe Cosmologies in dilatonic Einstein Gauss-Bonnet (dEGB) gravity, where the Gauss-Bonnet ter…
