Understanding Binary Systems -- a Comparison between COSMIC and MESA
Lailani Kenoly, A. Ken Luu, Celia Toral +4
We compare the evolution of binary systems evolved in the MESA stellar evolution code to those in the COSMIC population synthesis code. Our aim is to convey the robustness of the e…
COSMIC Variance in Binary Population Synthesis
Katelyn Breivik, Scott Coughlin, Michael Zevin +8
The formation and evolution of binary stars is a critical component of several fields in astronomy. The most numerous sources for gravitational wave observatories are inspiraling a…
Probing Massive Black Hole Binary Populations with LISA
Michael L. Katz, Luke Zoltan Kelley, Fani Dosopoulou +3
ESA and NASA are moving forward with plans to launch LISA around 2034. With data from the Illustris cosmological simulation, we provide analysis of LISA detection rates accompanied…
Astro2020 Science White Paper: Populations of Black Holes in Binaries
Thomas J. Maccarone, Laura Chomiuk, James Miller-Jones +9
Black holes in binary star systems are vital for understanding the process of pr oducing gravitational wave sources, understanding how supernovae work, and for p roviding fossil ev…
The Discovery Potential of Space-Based Gravitational Wave Astronomy
Neil J. Cornish, Emanuele Berti, Kelly Holley-Bockelmann +5
A space-based interferometer operating in the previously unexplored mHz gravitational band has tremendous discovery potential. If history is any guide, the opening of a new spectra…
Multi-Messenger Astrophysics with Pulsar Timing Arrays
Luke Zoltan Kelley, Maria Charisi, Sarah Burke-Spolaor +29
Pulsar timing arrays (PTAs) are on the verge of detecting low-frequency gravitational waves (GWs) from supermassive black hole binaries (SMBHBs). With continued observations of a l…
Astro2020 Decadal Science White Paper: Gravitational Wave Survey of Galactic Ultra Compact Binaries
Tyson B. Littenberg, Katelyn Breivik, Warren R. Brown +6
Ultra-compact binaries (UCBs) are systems containing compact or degenerate stars with orbital periods less than one hour. Tens of millions of UCBs are predicted to exist within the…
Astro2020 Decadal Science White Paper: The state of gravitational-wave astrophysics in 2020
Sean T. McWilliams, Robert Caldwell, Kelly Holley-Bockelmann +2
While still in its infancy, the budding field of gravitational-wave astronomy has so far exceeded most expectations, and the achievements that have already been made bode well for…
Multimessenger science opportunities with mHz gravitational waves
John Baker, Zoltán Haiman, Elena Maria Rossi +32
LISA will open the mHz band of gravitational waves (GWs) to the astronomy community. The strong gravity which powers the variety of GW sources in this band is also crucial in a num…
What we can learn from multi-band observations of black hole binaries
Curt Cutler, Emanuele Berti, Karan Jani +12
The LIGO/Virgo gravitational-wave (GW) interferometers have to-date detected ten merging black hole (BH) binaries, some with masses considerably larger than had been anticipated. S…
Post-Newtonian Dynamics in Dense Star Clusters: Binary Black Holes in the LISA Band
Kyle Kremer, Carl L. Rodriguez, Pau Amaro-Seoane +8
The dynamical processing of black holes in the dense cores of globular clusters (GCs), makes them efficient factories for producing binary black holes (BBHs). Here we explore the p…
LISA sources in Milky Way globular clusters
Kyle Kremer, Sourav Chatterjee, Katelyn Breivik +3
We explore the formation of double-compact-object binaries in Milky Way (MW) globular clusters (GCs) that may be detectable by the Laser Interferometer Space Antenna (LISA). We use…
Accreting Double white dwarf binaries: Implications for LISA
Kyle Kremer, Katelyn Breivik, Shane L. Larson +1
We explore the long-term evolution of mass-transferring white dwarf binaries undergoing both direct-impact and disk accretion and explore implications of such systems to gravitatio…
Busting Up Binaries: Encounters Between Compact Binaries and a Supermassive Black Hole
Eric Addison, Pablo Laguna, Shane Larson
Given the stellar density near the galactic center, close encounters between compact object binaries and the supermassive black hole are a plausible occurrence. We present results…
Search for long-lived gravitational-wave transients coincident with long gamma-ray bursts
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +875
Long gamma-ray bursts (GRBs) have been linked to extreme core-collapse supernovae from massive stars. Gravitational waves (GW) offer a probe of the physics behind long GRBs. We inv…
