Dynamics of Reheating in Modified Loop Quantum Cosmologies: mLQCI-I

Jared Fier, Rui Pan, Jamal Saeed +1

We study the reheating epoch and total bounce-to-present expansion in modified loop quantum cosmology using current observational determinations of the scalar amplitude and spectra…

Effects of the Ekpyrotic Mechanism on Inflationary Phase in mLQC-II

Jared Fier, Aqsa Fareed, Reena Danika Bendukuri +1

Bouncing cosmological models replace the big bang singularity with a regular bounce, but face a well-known obstacle: the anisotropic shear grows as a^(-6) during contraction, where…

Probing the Distribution and Nature of Dark Matter Around Supermassive Black Holes from EMRI and IMRI Gravitational Waves

Jared Fier, Farah Abdelshahed, Lilly Kowalczyk +2

The distribution of dark matter in the immediate vicinity of supermassive black holes remains poorly understood despite its importance for galaxy evolution and precision tests of g…

Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies

Christian Brown, Jared Fier, Brian Phillips +2

In bouncing cosmological models, either classical or quantum, the big bang singularity is replaced by a regular bounce. A challenging question in such models is how to keep the she…

Gravitational wave cosmology in Einstein-scalar-Gauss-Bonnet gravity

Jared Fier, Henry Han, Bowen Li +3

In the framework of Einstein-scalar-Gauss-Bonnet (EsGB) gravity, we systematically study gravitational waves (GWs), first produced by remote compact astrophysical sources and then…

Gravitational wave cosmology I: high frequency approximation

Jared Fier, Xiongjun Fang, Bowen Li +3

In this paper, we systematically study gravitational waves (GWs) produced by remote compact astrophysical sources. To describe such GWs properly, we introduce three scales, $λ, \;…

Singularities of plane gravitational waves and their memory effects

Tongzheng Wang, Jared Fier, Bowen Li +4

Similar to the Schwarzschild coordinates for spherical black holes, the Baldwin, Jeffery and Rosen (BJR) coordinates for plane gravitational waves are often singular, and extension…
