Multimessenger Parameter Estimation of GW170817
David Radice, Liang Dai
We combine gravitational wave (GW) and electromagnetic (EM) data to perform a Bayesian parameter estimation of the binary neutron star (NS) merger GW170817. The EM likelihood is co…
Pulsar-timing arrays, astrometry, and gravitational waves
Wenzer Qin, Kimberly K. Boddy, Marc Kamionkowski +1
We discuss the theory of pulsar-timing and astrometry probes of a stochastic gravitational-wave background with a recently developed "total-angular-momentum" (TAM) formalism for co…
Detecting Lensing-Induced Diffraction in Astrophysical Gravitational Waves
Liang Dai, Shun-Sheng Li, Barak Zackay +2
Gravitational waves emitted from compact binary coalescence can be subject to wave diffraction if they are gravitationally lensed by an intervening mass clump whose Schwarzschild t…
Parameter Estimation for GW170817 using Relative Binning
Liang Dai, Tejaswi Venumadhav, Barak Zackay
Relative binning is a new method for fast and accurate evaluation of the likelihood of gravitational wave strain data. This technique can be used to produce reliable posterior dist…
Relative Binning and Fast Likelihood Evaluation for Gravitational Wave Parameter Estimation
Barak Zackay, Liang Dai, Tejaswi Venumadhav
We present a method to accelerate the evaluation of the likelihood in gravitational wave parameter estimation. Parameter estimation codes compute likelihoods of similar waveforms,…
Implication of the Shape of the EDGES Signal for the 21 cm Power Spectrum
Alexander A. Kaurov, Tejaswi Venumadhav, Liang Dai +1
We revisit the 21 cm power spectrum from the epoch of cosmic dawn in light of the recent EDGES detection of the 21 cm global signal at frequencies corresponding to . The s…
Heating of the intergalactic medium by the cosmic microwave background during cosmic dawn
Tejaswi Venumadhav, Liang Dai, Alexander Kaurov +1
The intergalactic medium is expected to be at its coldest point before the formation of the first stars in the universe. Motivated by recent results from the EDGES experiment, we r…
Probing Dark Matter Subhalos in Galaxy Clusters Using Highly Magnified Stars
Liang Dai, Tejaswi Venumadhav, Alexander A. Kaurov +1
Luminous stars in background galaxies straddling the lensing caustic of a foreground galaxy cluster can be individually detected due to extreme magnification factors of …
