Primordial black holes generated by the non-minimal spectator field [PDF]

Science China Physics Mechanics and Astronomy, 2022
We improve and generalize the non-minimal curvaton model originally proposed in arXiv: 2112.12680 to a model in which a spectator field non-minimally couples to an inflaton field and the power spectrum of the perturbation of spectator field at small ...

No evidence for synchronization of the solar cycle by a "clock" [PDF]

Astronomy & Astrophysics, 2023
The length of the solar activity cycle fluctuates considerably. The temporal evolution of the corresponding cycle phase, that is, the deviation of the epochs of activity minima or maxima from strict periodicity, provides relevant information concerning ...

Fragmentation of a dynamically condensing radiative layer [PDF]

, 2009
In this paper, the stability of a dynamically condensing radiative gas layer is investigated by linear analysis. Our own time-dependent, self-similar solutions describing a dynamical condensing radiative gas layer are used as an unperturbed state.

Tensor perturbations from bounce inflation scenario in f(Q) gravity [PDF]

Science China Physics, Mechanics & Astronomy, 2023
In this paper, we construct a bounce inflation cosmological scenario in the framework of the modified symmetric teleparallel gravity, namely f(Q) theory, and investigate the tensor perturbations therein.

OGLE-2009-BLG-092/MOA-2009-BLG-137: A Dramatic Repeating Event With the Second Perturbation Predicted by Real-Time Analysis [PDF]

, 2010
We report the result of the analysis of a dramatic repeating gravitational microlensing event OGLE-2009-BLG-092/MOA-2009-BLG-137, for which the light curve is characterized by two distinct peaks with perturbations near both peaks.

Quasi-radial modes of pulsating neutron stars: numerical results for general-relativistic rigidly rotating polytropic models [PDF]

, 2014
In this paper we compute general-relativistic polytropic models simulating rigidly rotating, pulsating neutron stars. These relativistic compact objects, with a radius of $\sim 10 \, \mathrm{km}$ and mass between $\sim 1.4$ and $3.2$ solar masses, are ...

Gauge invariant perturbations of general spherically symmetric spacetimes [PDF]

Science China Physics Mechanics and Astronomy, 2022
In this paper, the gauge choices in general spherically symmetric spacetimes are explored. In particular, we construct the gauge invariant variables and the master equations for both the Detweiler easy gauge and the Regge-Wheeler gauge, respectively. The
