Systematic calibration error requirements for gravitational-wave detectors via the Cramér-Rao bound
Evan D. Hall, Craig Cahillane, Kiwamu Izumi +2
Gravitational-wave (GW) laser interferometers such as Advanced LIGO transduce spacetime strain into optical power fluctuation. Converting this optical power fluctuations back into…
Parameterized tests of the strong-field dynamics of general relativity using gravitational wave signals from coalescing binary black holes: Fast likelihood calculations and sensitivity of the method
Jeroen Meidam, Ka Wa Tsang, Janna Goldstein +15
Thanks to the recent discoveries of gravitational wave signals from binary black hole mergers by Advanced Laser Interferometer Gravitational Wave Observatory and Advanced Virgo, th…
The optimal search for an astrophysical gravitational-wave background
Rory Smith, Eric Thrane
Roughly every 2-10 minutes, a pair of stellar mass black holes merge somewhere in the Universe. A small fraction of these mergers are detected as individually resolvable gravitatio…
Star Formation of Merging Disk Galaxies with AGN Feedback Effects
Jongwon Park, Rory Smith, Sukyoung K. Yi
Using numerical hydrodynamics code, we perform various idealized galaxy merger simulations to study the star formation (SF) of two merging disk galaxies. Our simulations include ga…
Discovery of ram-pressure stripped gas around an elliptical galaxy in Abell 2670
Yun-Kyeong Sheen, Rory Smith, Yara Jaffe +7
Studies of cluster galaxies are increasingly finding galaxies with spectacular one-sided tails of gas and young stars, suggestive of intense ram-pressure stripping. These so-called…
Phase-space Analysis in the Group and Cluster environment: Time since Infall and Tidal Mass Loss
Jinsu Rhee, Rory Smith, Hoseung Choi +4
Using the latest cosmological hydrodynamic N-body simulations of groups and clusters, we study how location in phase-space coordinates at can provide information on envir…
A History of HI Stripping in Virgo: A Phase-space View of VIVA Galaxies
Hyein Yoon, Aeree Chung, Rory Smith +1
We investigate the orbital histories of Virgo galaxies at various stages of HI gas stripping. In particular, we compare the location of galaxies with different HI morphology in pha…
A Surrogate Model of Gravitational Waveforms from Numerical Relativity Simulations of Precessing Binary Black Hole Mergers
Jonathan Blackman, Scott E. Field, Mark A. Scheel +4
We present the first surrogate model for gravitational waveforms from the coalescence of precessing binary black holes. We call this surrogate model NRSur4d2s. Our methodology sign…
