The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries
David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67
In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…
Reconstructing patchy helium reionization using the cosmic microwave background and large-scale structure
Mesut ÃalıÅkan, Neha Anil Kumar, Selim C. Hotinli +1
The intergalactic helium became fully ionized by the end of cosmic noon (). Similarly to the reionization of hydrogen, helium reionization is expected to be patchy, driven…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
Linear polarization of the stochastic gravitational-wave background with pulsar timing arrays
Neha Anil Kumar, Mesut ÃalıÅkan, Gabriela Sato-Polito +2
Pulsar-timing collaborations have recently reported evidence for the detection of an isotropic stochastic gravitational-wave background consistent with one sourced by a population…
Probing wave-optics effects and low-mass dark matter halos with lensing of gravitational waves from massive black holes
Mesut ÃalıÅkan, Neha Anil Kumar, Lingyuan Ji +4
The Laser Interferometer Space Antenna (LISA) will detect gravitational waves (GWs) emitted by massive black hole binaries (MBHBs) in the low-frequency (mHz) band. Low-mass l…
Dissecting the Stochastic Gravitational Wave Background with Astrometry
Mesut ÃalıÅkan, Yifan Chen, Liang Dai +3
Astrometry, the precise measurement of star motions, offers an alternative avenue to investigate low-frequency gravitational waves through the spatial deflection of photons, comple…
