Set them free: extending RAMCOAL to model massive black hole triplets in hydrodynamical simulations of galaxies
Kunyang Li, Ricarda S. Beckmann, Yohan Dubois +1
Massive black hole binaries (MBHBs), and the higher-order multiples produced by repeated galaxy mergers, spend part of their lives in dynamical regimes that cosmological simulation…
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…
Tracking on-the-fly massive black hole binary evolution and coalescence in galaxy simulations: RAMCOAL
Kunyang Li, Marta Volonteri, Yohan Dubois +2
The detection of gravitational waves (GWs) from massive black hole binary (MBHB) coalescence motivates the development of a sub-grid model. We present RAMCOAL, integrated into the…
Massive Black Hole Binaries from the TNG50-3 Simulation: II. Using Dual AGNs to Predict the Rate of Black Hole Mergers
Kunyang Li, Tamara Bogdanović, David R. Ballantyne +1
Dual active galaxy nuclei (dAGNs) trace the population of post-merger galaxies and are the precursors to massive black hole (MBH) mergers, an important source of gravitational wave…
Massive Black Hole Binaries from the TNG50-3 Simulation: I. Coalescence and LISA Detection Rates
Kunyang Li, Tamara Bogdanović, David R. Ballantyne +1
We evaluate the cosmological coalescence and detection rates for massive black hole (MBH) binaries targeted by the gravitational wave observatory Laser Interferometer Space Antenna…
The Detectability of Kiloparsec Scale Dual AGNs: The Impact of Galactic Structure and Black Hole Orbital Properties
Kunyang Li, David R. Ballantyne, Tamara Bogdanović
Observational searches for dual active galactic nuclei (dAGNs) at kiloparsec separations are crucial for understanding the role of galaxy mergers in the evolution of galaxies. In a…
The Pairing Probability of Massive Black Holes in Merger Galaxies in the Presence of Radiative Feedback
Kunyang Li, Tamara Bogdanovic, David R. Ballantyne
Dynamical friction (DF) against stars and gas is thought to be an important mechanism for orbital evolution of massive black holes (MBHs) in merger remnant galaxies. Recent theoret…
Pairing of Massive Black Holes in Merger Galaxies Driven by Dynamical Friction
Kunyang Li, Tamara Bogdanovic, David R. Ballantyne
Motivated by observational searches for massive black hole (MBH) pairs at kiloparsec separations we develop a semi-analytic model to describe their orbital evolution under the infl…
Relativistic Astronomy
Bing Zhang, Kunyang Li
The "Breakthrough Starshot" aims at sending near-speed-of-light cameras to nearby stellar systems in the future. Due to the relativistic effects, a trans-relativistic camera natura…
The JetCurry Code. I. Reconstructing Three-Dimensional Jet Geometry from Two-Dimensional images
Kunyang Li, Katie Kosak, Sayali S. Avachat +1
We present a reconstruction of jet geometry models using numerical methods based on a Markov ChainMonte Carlo (MCMC) and limited memory Broyden-Fletcher-Goldfarb-Shanno (BFGS) opti…
Astronomical Catalogs for Locating Gravitational-wave Events
Kunyang Li, Roy Williams
Gravitational wave transients are caused by some of the most energetic events in the Universe, and a precise location would allow deep examination of the counterpart by electromagn…
Multi-wavelength Polarimetry and Variability Study of M87 Jet
Sayali S Avachat, Eric S Perlman, William B Sparks +2
We present a high resolution polarimetry and variability study of the M87 jet using VLA and HST data taken during 2002 to 2008. Both data-sets have an angular resolution as high as…
