Fundamental Physics with the Square Kilometre Array
A. Weltman, P. Bull, S. Camera +50
The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity an…
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,…
Identifying strongly lensed gravitational wave signals from binary black hole mergers
K. Haris, Ajit Kumar Mehta, Sumit Kumar +2
Based on the rate of gravitational-wave (GW) detections by Advanced LIGO and Virgo, we expect these detectors to observe hundreds of binary black hole mergers as they achieve their…
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…
