The discovery of gravitational waves from binary black hole mergers has renewed interest in primordial black holes forming a part of the dark matter density of our Universe. Various tests have been proposed to test this hypothesis. One of the cleanest tests is the lensing of fast radio bursts. In this situation, the presence of a compact object near the line of sight produces two images of the radio burst. If the images are sufficiently separated in time, this technique can constrain the…

Constraints on the abundance of primordial black holes with different mass distributions from lensing of fast radio bursts
Primordial black holes (PBHs) has been considered to form a part of dark matter for a long time but the possibility has been poorly constrained over a wide mass range, including the stellar mass
First Constraints on Compact Dark Matter from Fast Radio Burst Microstructure
Despite existing constraints, it remains possible that up to 35% of all dark matter is comprised of compact objects, such as the black holes in the 10–100 M⊙ range whose existence has been confirmed
Looking for MACHOs in the spectra of fast radio bursts
We explore a novel search strategy for dark matter in the form of massive compact halo objects (MACHOs) such as primordial black holes or dense mini-haloes in the mass range from $10^{-4}\,
Gravitational microlensing constraints on primordial black holes by Euclid
Primordial black holes (PBHs) may form in the early stages of the Universe via the collapse of large density perturbations. Depending on the formation mechanism, PBHs may exist and populate today the
Low Mass Black Holes from Dark Core Collapse.
It is shown that redshift dependence of the merger rate can be used as a probe of the transmuted origin of low mass black holes, and pointed out several avenues to test the proposal.
Neutrino and Positron Constraints on Spinning Primordial Black Hole Dark Matter.
A comprehensive study of the detectability of primordial black holes with non-negligible spin, via the searches for the neutrinos and positrons in the MeV energy range, finds that spin-a fundamental property that has a strong effect on its evaporation rate, is found.
Probing dynamics of boson stars by fast radio bursts and gravitational wave detection
Boson stars may consist of a new type of light singlet scalar particles with nontrivial self-interactions, and may compose a fraction of the dark matter in the Universe. In this work, we study the

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
The physics of fast radio bursts
In 2007, a very bright radio pulse was identified in the archival data of the Parkes Telescope in Australia, marking the beginning of a new research branch in astrophysics. In 2013, this kind of


Pulsar timing can constrain primordial black holes in the LIGO mass window
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
New limits on primordial black hole dark matter from an analysis of Kepler source microlensing data.
It is found that PBH DM with masses in the range 2 × 10(-9) M[Symbol: see text] to 10(-7)M cannot make up the entirety of the DM in the Milky Way.
Constraints on the Primordial Black Hole Abundance from the First Advanced LIGO Observation Run Using the Stochastic Gravitational-Wave Background.
It is shown that Advanced LIGO's first observation run gives the best constraint on the primordial black hole abundance in the mass range 1M_{⊙}≲M_{PBH]≲100M_{ ⊙}, pushing the previous microlensing and dwarf galaxy dynamics constraints tighter by 1 order of magnitude.
Primordial Black Holes as a Dark Matter Candidate Are Severely Constrained by the Galactic Center 511 keV γ-Ray Line.
These constraints are the most stringent in the literature and show that primordial black holes contribute to less than 1% of the dark matter density.
Limits on the Mass and Abundance of Primordial Black Holes from Quasar Gravitational Microlensing
The idea that dark matter can be made of intermediate-mass primordial black holes (PBHs) in the 10 M⊙ ≲ M ≲ 200 M⊙ range has recently been reconsidered, particularly in the light of the detection of
Multi-wavelength astronomical searches for primordial black holes
If primordial black holes of 𝒪(1–100) M⊙ constitute a significant portion of the dark matter in the Universe, they should be very abundant in our Galaxy. We present here a detailed analysis of the
Limits on Stellar-Mass Compact Objects as Dark Matter from Gravitational Lensing of Type Ia Supernovae.
Borders on the abundance of compact objects from gravitational lensing of type Ia supernovae (SNe) constrain early-Universe models that predict stellar-mass PBH production and strengthen the case for lighter forms of DM, including new elementary particles.
Cosmic microwave background limits on accreting primordial black holes
Interest in the idea that primordial black holes (PBHs) might comprise some or all of the dark matter has recently been rekindled following LIGO’s first direct detection of a binary-black-hole
