Microlensing effects of wormholes associated to blackhole spacetimes
Ke Gao, Lei-Hua Liu, Mian Zhu
In this paper, we investigate the microlensing effects of wormholes associated to black hole spacetimes. Specifically, we work on three typical wormholes (WH): Schwarzschild WH, Ke…
Sudden braking and turning with a two-field potential bump: primordial black hole formation
Chengjie Fu, Chao Chen
We investigate the amplification of curvature perturbations in a two-field inflation model featuring a Gaussian potential bump. When the inflaton encounters a potential bump along…
Missing one-loop contributions in secondary gravitational waves
Chao Chen, Atsuhisa Ota, Hui-Yu Zhu +1
We find several missing one-loop-order contributions in previous considerations about secondary gravitational waves induced at nonlinear order in cosmological perturbations. We con…
JWST's PEARLS: Prime Extragalactic Areas for Reionization and Lensing Science: Project Overview and First Results
Rogier A. Windhorst, Seth H. Cohen, Rolf A. Jansen +82
We give an overview and describe the rationale, methods, and first results from NIRCam images of the JWST "Prime Extragalactic Areas for Reionization and Lensing Science" ("PEARLS"…
Microlensing effect of charged spherically symmetric wormhole
Lei-Hua Liu, Mian Zhu, Wentao Luo +2
We systematically investigate the microlensing effect of charged spherically symmetric wormhole, where the light source is remote from the throat. Remarkably, there will be at most…
A Novel Solution to the Gravitino Problem
Yu-Cheng Qiu, S. -H. Henry Tye
In a general phenomenological model with local supersymmetry, the amount of massive gravitinos produced in early universe tends to violate the known dark matter density bound by ma…
Toward Cosmological Standard Timers in Primordial Black Hole Binaries
Qianhang Ding
We propose that primordial black hole (PBH) binary systems can lead to standard timers in tracking the evolution of the Universe. Through gravitational waves from monochromatic PBH…
Induced gravitational waves from statistically anisotropic scalar perturbations
Chao Chen, Atsuhisa Ota
Scalar-induced gravitational waves (SIGWs) are attracting growing attention for probing extremely short-scale scalar perturbations via gravitational wave measurements. In this pape…
Numerical prescriptions of early-time divergences of the in-in formalism
Duc Huy Tran, Yi Wang, Juanyi Yang +1
In quantum field theory, the in and out states can be related to the full Hamiltonian by the prescription. A Wick rotation can further bring the correlation functions to Eucli…
Obstacles from interstellar matters and distortion in warp drive superluminal travel scenario
Siyu Bian, Yi Wang, Zun Wang +1
We investigate obstacles of superluminal "warp drive" travels from interactions with interstellar matter and from curvature effects. The effect of collision of interstellar dust pa…
