Gravitational waves from mergers of Population III binary black holes: roles played by two evolution channels
Boyuan Liu, Tilman Hartwig, Nina S. Sartorio +6
The gravitational wave (GW) signal from binary black hole (BBH) mergers is a promising probe of Population III (Pop III) stars. To fully unleash the power of the GW probe, one impo…
Massive black hole merger rates: the effect of kpc separation wandering and supernova feedback
Enrico Barausse, Irina Dvorkin, Michael Tremmel +2
We revisit the predictions for the merger rate of massive black hole binaries detectable by the Laser Interferometer Space Antenna (LISA) and their background signal for pulsar-tim…
Cosmological evolution of the Nitrogen abundance
Elisabeth Vangioni, Irina Dvorkin, Keith A. Olive +5
The abundance of nitrogen in the interstellar medium is a powerful probe of star for- mation processes over cosmological timescales. Since nitrogen can be produced both in massive…
The nightmare scenario: measuring the stochastic gravitational-wave background from stalling massive black-hole binaries with pulsar-timing arrays
Irina Dvorkin, Enrico Barausse
Massive black-hole binaries, formed when galaxies merge, are among the primary sources of gravitational waves targeted by ongoing Pulsar Timing Array (PTA) experiments and the upco…
Evolution of dispersion in the cosmic deuterium abundance
Irina Dvorkin, Elisabeth Vangioni, Joseph Silk +2
Deuterium is created during Big Bang Nucleosynthesis, and, in contrast to the other light stable nuclei, can only be destroyed thereafter by fusion in stellar interiors. In this pa…
Evolution of the gas mass fraction in galaxy clusters
Irina Dvorkin, Yoel Rephaeli
The mass fraction of hot gas in clusters is a basic quantity whose level and dependence on the cluster mass and redshift are intimately linked to all cluster X-ray and SZ measures.…
