We explore the observational implications of a model in which primordial black holes (PBHs) with a broad birth mass function ranging in mass from a fraction of a solar mass to ∼106 M ⊙, consistent with current observational limits, constitute the dark matter (DM) component in the universe. The formation and evolution of dark matter and baryonic matter in this PBH-Λ cold dark matter (ΛCDM) universe are presented. In this picture, PBH-DM mini-halos collapse earlier than in standard ΛCDM, baryons… 
Formation and Abundance of Late-forming Primordial Black Holes as Dark Matter
We propose a novel mechanism where primordial black hole (PBH) dark matter is formed much later in the history of the universe, between the epochs of Big Bang nucleosynthesis and cosmic microwave
Fermi-GBM Observation of GRB 090717034: χ 2 Test Confirms Evidence of Gravitational Lensing by a Supermassive Black Hole with a Million Solar Mass
Gravitational lensing of gamma-ray bursts (GRBs) can provide an opportunity to probe the massive compact objects in the universe at different redshifts. We have discovered two consecutive pulses in
Snowmass2021 Cosmic Frontier White Paper:Primordial Black Hole Dark Matter
Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the dark matter and provide a unique window into the high-energy physics of the early universe. This white paper
Snowmass2021 Cosmic Frontier White Paper: Probing dark matter with small-scale astrophysical observations
The current understanding of dark matter comes largely from measurements of the total matter content in the universe, from the distribution of gravitating matter on very large scales, and from

Massive Primordial Black Holes as Dark Matter and their detection with Gravitational Waves
Massive Primordial Black Holes (MPBH) can be formed after inflation due to broad peaks in the primordial curvature power spectrum that collapse gravitationally during the radiation era, to form
Primordial black holes from the QCD epoch: linking dark matter, baryogenesis, and anthropic selection
If primordial black holes (PBHs) formed at the quark-hadron epoch, their mass must be close to the Chandrasekhar limit, this also being the characteristic mass of stars. If they provide the dark
SMBH seeds from dissipative dark matter
The existence of supermassive black holes (SMBHs) with masses greater than ∼ 109 M ☉ at high redshift (z ≳ 7) is difficult to accommodate in standard astrophysical scenarios. We study the possibility
The clustering of undetected high-redshift black holes and their signatures in cosmic backgrounds
There exist hitherto unexplained fluctuations in the cosmic infrared background on arcminute scales and larger. These have been shown to cross-correlate with the cosmic X-ray background, leading
Primordial black holes and the origin of the matter–antimatter asymmetry
We review here a new scenario of hot spot electroweak baryogenesis where the local energy released in the gravitational collapse to form primordial black holes (PBHs) at the quark-hadron (QCD) epoch
Effect of Primordial Black Holes on the Cosmic Microwave Background and Cosmological Parameter Estimates
We investigate the effect of nonevaporating primordial black holes (PBHs) on the ionization and thermal history of the universe. X-rays emitted by gas accretion onto PBHs modify the cosmic

Growing supermassive black holes ( ) that power luminous quasars from light seeds—the remnants of the first stars—within a Gyr of the Big Bang poses a timing challenge. The formation of massive black
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
