The recent discovery of gravitational waves from merging black holes has generated interest in primordial black holes as a possible component of the dark matter. In this paper, we show that pulsar timing may soon have sufficient data to constrain $1$-$1000\,M_{\odot}$ primordial black holes via the non-detection of a third-order Shapiro time delay as the black holes move around the Galactic halo. We present the results of a Monte Carlo simulation which suggests that future data from known…

Pulsar Timing Array Constraints on Primordial Black Holes with NANOGrav 11-Year Dataset.

This work performs the first direct search for the signals of SIGWs accompanying the formation ofPBHs in the North American Nanohertz Observatory for Gravitational waves (NANOGrav) 11-year dataset, and places a stringent upper limit on the abundance of PBHs at 95% confidence level.

Pulsar timing probes of primordial black holes and subhalos

Pulsars act as accurate clocks, sensitive to gravitational redshift and acceleration induced by transiting clumps of matter. We study the sensitivity of pulsar timing arrays (PTAs) to single

Merger rate of primordial black-hole binaries

Primordial black holes (PBHs) have long been a candidate for the elusive dark matter (DM), and remain poorly constrained in the ~20-100 Msun mass range. PBH binaries were recently suggested as the

Solving puzzles of GW150914 by primordial black holes

The black hole binary properties inferred from the LIGO gravitational wave signal GW150914 posed several serious problems. The high masses and low effective spin of black hole binary can be explained

Primordial-black-hole mergers in dark-matter spikes

It has been suggested that primordial black holes (PBHs) of roughly 30 solar masses could make up the dark matter and if so, might account for the recent detections by LIGO involving binary black

Constraints on primordial black holes

The constraints on the fraction of the Universe that may have gone into primordial black holes (PBHs) over the mass range 10−5 to 1050 g are updated and even if PBHs make a small contribution to the DM, they could play an important cosmological role and provide a unique probe of the early Universe.

Primordial black holes as a dark matter candidate

The detection of gravitational waves from mergers of tens of Solar mass black hole binaries has led to a surge in interest in Primordial Black Holes (PBHs) as a dark matter candidate. We aim to

Early structure formation in primordial black hole cosmologies

Cold dark matter (CDM) could be composed of primordial black holes (PBH) in addition to or instead of more orthodox weakly interacting massive particle dark matter (PDM). We study the formation of

Cosmological implications of primordial black holes

The possibility that a relevant fraction of the dark matter might be comprised of Primordial Black Holes (PBHs) has been seriously reconsidered after LIGO's detection of a ∼ 30 M⊙ binary black holes

Searching for Primordial Black Hole Dark Matter with Pulsar Timing Arrays

We discuss the possibility of detecting the presence of primordial black holes (PBHs), such as those that might account for galactic dark matter, using modification of pulsar timing residuals when

Did LIGO Detect Dark Matter?

It is considered that the black-hole (BH) binary detected by LIGO may be a signature of dark matter, and reasonable estimates span a range that overlaps the 2-53  Gpc^{-3} yr^{-1} rate estimated from GW150914, thus raising the possibility that LigO has detected PBH dark matter.

The recent discovery of gravitational waves from mergers of ∼10 M⊙ black hole binaries has stimulated interested in primordial black hole (PBH) dark matter in this mass range. Microlensing and

Primordial Black Hole Scenario for the Gravitational-Wave Event GW150914.

The abundance of PBHs required to explain the suggested lower bound on the event rate roughly coincides with the existing upper limit set by the nondetection of the cosmic microwave background spectral distortion, which implies that the proposed PBH scenario may be tested in the not-too-distant future.

Enhanced exploration for primordial black holes using pulsar timing arrays

We investigate the capability of pulsar timing arrays as a probe of primordial black holes (PBHs), which might constitute the Galactic dark matter. A PBH passing nearby the Earth or a pulsar gives an

Can the known millisecond pulsars help in the detection of intermediate-mass black holes at the centers of globular clusters?

We consider the possibility of detecting intermediate-mass (103–104M⊙) black holes, whose existence at the centers of globular clusters is expected from optical and infrared observations, using

Pulsar timing arrays (PTAs) are placing increasingly stringent constraints on the strain amplitude of continuous gravitational waves emitted by supermassive black hole binaries on subparsec scales.

Gravitational-wave background as a probe of the primordial black-hole abundance.

It is shown that pulsar timing data essentially rule out PBHs with 10;{2}-10;{4}M_{middle dot in circle}, which were previously considered as a candidate of intermediate-mass black holes, and that PBHS with a mass range of 10;20 to 10;26 g, which serves as a candidates of dark matter, may be probed by future space-based laser interferometers and atomic interferometer.
