Title: Gravitational waves from primordial black holes and new weak scale phenomena

Abstract

Here, we entertain the possibility that primordial black holes of mass ~ (10²⁶–10²⁹)g, with Schwarzschild radii of O(cm), constitute ~ 10% or more of cosmic dark matter, as allowed by various constraints. These black holes would typically originate from cosmological eras corresponding to temperatures O(10-100)GeV, and may be associated with first order phase transitions in the visible or hidden sectors. In case these small primordial black holes get captured in orbits around neutron stars or astrophysical black holes in our galactic neighborhood, gravitational waves from the resulting “David and Goliath (D&G)” binaries could be detectable at Advanced LIGO or Advanced Virgo for hours or more, possibly over distances of O(10)Mpc encompassing the Local Supercluster of galaxies. The proposed Einstein Telescope would further expand the reach for these signals. A positive signal could be further corroborated by the discovery of new particles in the O(10-100)GeV mass range, and potentially also the detection of long wavelength gravitational waves originating from the first order phase transition era.

Gravitational wave background from mergers of large primordial black holes

Journal Article Deng, Heling - Journal of Cosmology and Astroparticle Physics

The Peters formula, which tells how the coalescence time of a binary system emitting gravitational radiation is determined by the initial size and shape of the elliptic orbit, is often used in estimating the merger rate of primordial black holes and the gravitational wave background from the mergers. Valid as it is in some interesting scenarios, such as the analysis of the LIGO-Virgo events, the Peters formula fails to describe the coalescence time if the orbital period of the binary exceeds the value given by the formula. This could underestimate the event rate of mergers that occur before the cosmic time t ~ 10¹³ s. As a result, the energy density spectrum of the gravitational wave background could develop a peak, which is from mergers occurring at either t ~ 10¹³ s (for black holes with mass M ≳ 10⁸ M_⊙) or t ~ 10²⁶(M/M_⊙)^-5/3 s (for 10⁵ M_⊙ ≲ M ≲ 10⁸ M_⊙). This can be used to constrain the fraction of dark matter in primordial black holes (denoted by f) if potential probes (such as SKA and U-DECIGO) do not discover such a background, with the result f ≲ 10^-6–10^-4 for the mass range 10– 10⁹ M_⊙. We then consider the effect of mass accretion onto primordial black holes at redshift z ~ 10, and find that the merger rate could drop significantly at low redshifts. The spectrum of the gravitational wave background thus gets suppressed at the high-frequency end. This feature might be captured by future detectors such as ET and CE for initial mass M = Scriptmore »« less

Is GW170817 a Multimessenger Neutron Star-Primordial Black Hole Merger?

Journal Article Tsai, Yu-Dai ; Palmese, Antonella ; Profumo, Stefano ; ... - TBD

We investigate the possibility of the gravitational-wave event GW170817 being a light, solar-mass black hole (BH) - neutron star (NS) merger. We explore two exotic scenarios involving primordial black holes (PBH) that could produce such an event, taking into account available observational information on NGC 4993. First, we entertain the possibility of dynamical NS-PBH binary formation where a solar-mass PBH and a NS form a binary through gravitational interaction. We find that while dynamical NS-PBH formation could account for the GW170817 event, the rate is highly dependent on unknown density contrast factors and could potentially be affected by galaxy mergers.more »« less

Transmuted gravity wave signals from primordial black holes

Journal Article Takhistov, Volodymyr - Physics Letters B

Primordial black holes (PBHs) interacting with stars in binaries lead to a new class of gravity wave signatures that we explore. A small 10^-16-10^-7M_⊙ PBH captured by a neutron star or a white dwarf will eventually consume the host. The resulting black hole will have a mass of only ~0.5-2.5M_⊙, not expected from astrophysics. For a double neutron star binary system this leads to a transmutation into a black hole–neutron star binary, with a gravity wave signal detectable by the LIGO-VIRGO network. For a neutron star–white dwarf system this leads to a black hole–white dwarf binary, with a gravity wavemore »« less

Induced gravitational wave background and primordial black holes

Journal Article Bugaev, Edgar ; Klimai, Peter - Physical Review. D, Particles Fields

We calculate the frequency dependence of the gravitational wave background arising at second order of cosmological perturbation theory due to mixing of tensor and scalar modes. The calculation of the induced gravitational background is performed for two special cases: for the power spectrum of scalar perturbations which has a peak at some scale and for the scalar spectrum predicted by the inflationary model with the running mass potential. We show that the amplitudes of the induced gravitational background, in the frequency region {approx}10{sup -3}-10{sup 3} Hz, are effectively constrained by results of studies of primordial black hole production in themore »« less

Solar mass primordial black holes in moduli dominated universe

Journal Article Bhattacharya, Sukannya ; Das, Anirban ; Dutta, Koushik - Journal of Cosmology and Astroparticle Physics

In this report we explore the prospect of producing primordial black holes around the solar mass region during an early matter domination epoch. The early matter-dominated epoch can arise when a moduli field comes to dominate the energy density of the Universe prior to big bang nucleosynthesis. The absence of radiation pressure during a matter-dominated epoch enhances primordial black hole formation from the gravitational collapse of primordial density fluctuations. In particular, we find that primordial black holes are produced in the 0.1 - 10M^⊙ mass range with a favorable choice of parameters in the theory. However, they cannot explain allmore »« less
