Retainment of r-process material in dwarf galaxies
Paz Beniamini, Irina Dvorkin, Joe Silk
The synthesis of -process elements is known to involve extremely energetic explosions. At the same time, recent observations find significant -process enrichment even in extr…
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…
Exploring stellar evolution with gravitational-wave observations
Irina Dvorkin, Jean-Philippe Uzan, Elisabeth Vangioni +1
Recent detections of gravitational waves from merging binary black holes opened new possibilities to study the evolution of massive stars and black hole formation. In particular, s…
Gravitational wave searches for ultralight bosons with LIGO and LISA
Richard Brito, Shrobana Ghosh, Enrico Barausse +5
Ultralight bosons can induce superradiant instabilities in spinning black holes, tapping their rotational energy to trigger the growth of a bosonic condensate. Possible observation…
Stochastic and resolvable gravitational waves from ultralight bosons
Richard Brito, Shrobana Ghosh, Enrico Barausse +5
Ultralight scalar fields around spinning black holes can trigger superradiant instabilities, forming a long-lived bosonic condensate outside the horizon. We use numerical solutions…
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…
