The existence of primordial black holes (PBHs), which may form from the collapse of matter overdensities shortly after the Big Bang, is still under debate. Among the potential signatures of PBHs are gravitational waves (GWs) emitted from binary black hole (BBH) mergers at redshifts

Abstract z ≳ 30, where the formation of astrophysical black holes is unlikely. Future groundbased GW detectors, the Cosmic Explorer and Einstein Telescope, will be able to observe equalmass BBH mergers with total mass of at such distances. In this work, we investigate whether the redshift measurement of a single BBH source can be precise enough to establish its primordial origin. We simulate BBHs of different masses, mass ratios and orbital orientations. We show that for BBHs with total masses between 20 $\mathit{\ue23b}(10\u2013100)\phantom{\rule{0.50em}{0ex}}{M}_{\odot}$M _{⊙}and 40M _{⊙}merging atz ≥ 40, one can inferz > 30 at up to 97% credibility, with a network of one Einstein Telescope, one 40 km Cosmic Explorer in the US, and one 20 km Cosmic Explorer in Australia. This number reduces to 94% with a smaller network made of one Einstein Telescope and one 40 km Cosmic Explorer in the US. We also analyze how the measurement depends on the Bayesian priors usedmore » 
Abstract We present the stellar population properties of 69 short gammaray burst (GRB) host galaxies, representing the largest uniformly modeled sample to date. Using the
Prospector stellar population inference code, we jointly fit photometry and/or spectroscopy of each host galaxy. We find a population median redshift of (68% confidence), including nine photometric redshifts at $z={0.64}_{0.32}^{+0.83}$z ≳ 1. We further find a median massweighted age oft _{m}= Gyr, stellar mass of log( ${0.8}_{0.53}^{+2.71}$M _{*}/M _{⊙}) = , star formation rate of SFR = ${9.69}_{0.65}^{+0.75}$ ${1.44}_{1.35}^{+9.37}$M _{⊙}yr^{−1}, stellar metallicity of log(Z _{*}/Z _{⊙}) = , and dust attenuation of ${0.38}_{0.42}^{+0.44}$ mag (68% confidence). Overall, the majority of short GRB hosts are starforming (≈84%), with small fractions that are either transitioning (≈6%) or quiescent (≈10%); however, we observe a much larger fraction (≈40%) of quiescent and transitioning hosts at ${A}_{V}={0.43}_{0.36}^{+0.85}$z ≲ 0.25, commensurate with galaxy evolution. We find that short GRB hosts populate the starforming main sequence of normal field galaxies, but do not include as many highmass galaxies as the general galaxy population, implying that their binary neutron star (BNS) merger progenitors are dependent on a combination of host star formation and stellar mass. The distribution of ages and redshifts implies a broad delaytime distribution,more » 
ABSTRACT Making the most of the rapidly increasing population of gravitationalwave detections of black hole (BH) and neutron star (NS) mergers requires comparing observations with population synthesis predictions. In this work, we investigate the combined impact from the key uncertainties in population synthesis modelling of the isolated binary evolution channel: the physical processes in massive binarystar evolution and the star formation history as a function of metallicity, Z, and redshift z, $\mathcal {S}(Z,z)$. Considering these uncertainties, we create 560 different publicly available model realizations and calculate the rate and distribution characteristics of detectable BHBH, BHNS, and NSNS mergers. We find that our stellar evolution and $\mathcal {S}(Z,z)$ variations can combined impact the predicted intrinsic and detectable merger rates by factors in the range 102–104. We find that BHBH rates are dominantly impacted by $\mathcal {S}(Z,z)$ variations, NSNS rates by stellar evolution variations and BHNS rates by both. We then consider the combined impact from all uncertainties considered in this work on the detectable mass distribution shapes (chirp mass, individual masses, and mass ratio). We find that the BHNS mass distributions are predominantly impacted by massive binarystar evolution changes. For BHBH and NSNS, we find that both uncertainties are important. Wemore »

Abstract Gravitationalwave (GW) detections of binary black hole (BH) mergers have begun to sample the cosmic BH mass distribution. The evolution of single stellar cores predicts a gap in the BH mass distribution due to pairinstability supernovae (PISNe). Determining the upper and lower edges of the BH mass gap can be useful for interpreting GW detections of merging BHs. We use
MESA to evolve single, nonrotating, massive helium cores with a metallicity ofZ = 10^{−5}, until they either collapse to form a BH or explode as a PISN, without leaving a compact remnant. We calculate the boundaries of the lower BH mass gap for Sfactors in the range S(300 keV) = (77,203) keV b, corresponding to the ±3σ uncertainty in our highresolution tabulated^{12}C(α ,γ )^{16}O reaction rate probability distribution function. We extensively test temporal and spatial resolutions for resolving the theoretical peak of the BH mass spectrum across the BH mass gap. We explore the convergence with respect to convective mixing and nuclear burning, finding that significant time resolution is needed to achieve convergence. We also test adopting a minimum diffusion coefficient to help lowerresolution models reach convergence. We establish a new lower edge of the upper mass gap asM _{lower}≃ ${60}_{14}^{+32}$M _{⊙}from the ±3σ uncertainty inmore » 
Abstract The accretion disks of active galactic nuclei (AGNs) are promising locations for the merger of compact objects detected by gravitational wave (GW) observatories. Embedded within a baryonrich, highdensity environment, mergers within AGNs are the only GW channel where an electromagnetic (EM) counterpart must occur (whether detectable or not). Considering AGNs with unusual flaring activity observed by the Zwicky Transient Facility (ZTF), we describe a search for candidate EM counterparts to binary black hole (BBH) mergers detected by LIGO/Virgo in O3. After removing probable false positives, we find nine candidate counterparts to BBH mergers during O3 (seven in O3a, two in O3b) with a
p value of 0.0019. Based on ZTF sky coverage, AGN geometry, and merger geometry, we expect ≈3(N _{BBH}/83)(f _{AGN}/0.5) potentially detectable EM counterparts from O3, whereN _{BBH}is the total number of observed BBH mergers andf _{AGN}is the fraction originating in AGNs. Further modeling of breakout and flaring phenomena in AGN disks is required to reduce our falsepositive rate. Two of the events are also associated with mergers with total masses >100M _{⊙}, which is the expected rate for O3 if hierarchical (largemass) mergers occur in the AGN channel. Candidate EM counterparts in future GW observing runs can be better constrained by coverage ofmore »
