Impact of the spherical harmonic mode with memory on parameter estimation for ground-based detectors
Maria Rosselló-Sastre, Sascha Husa, Sayantani Bera +1
We recently presented an efficient and accurate waveform model for the spherical harmonic mode including both the displacement memory contribution and the ringdown oscillat…
Fast frequency-domain gravitational waveforms for precessing binaries with a new twist
Marta Colleoni, Felip A. Ramis Vidal, Cecilio García-Quirós +2
Gravitational waveform (GW) models are a core ingredient for the analysis of compact binary mergers observed by current ground-based interferometers. We focus here on a specific cl…
A waveform model for the missing quadrupole mode from black hole coalescence: memory effect and ringdown of the spherical harmonic
Maria Rosselló-Sastre, Sascha Husa, Sayantani Bera
In this paper we describe a model for the spherical harmonic mode of the gravitational wave signal emitted by the coalescence of binary black holes, in particular,…
Testing Gravity with Binary Black Hole Gravitational Waves
Marta Colleoni, N. V. Krishnendu, Pierre Mourier +2
General Relativity (GR) remains the most accurate theory of gravity to date. It has passed many experimental tests in the Solar System as well as binary pulsar, cosmological and gr…
Prospects of Probing Dark Matter Condensates with Gravitational Waves
Shreya Banerjee, Sayantani Bera, David F. Mota
The Lambda-Cold Dark Matter model explains cosmological observations most accurately till date. However, it is still plagued with various shortcomings at galactic scales. Models of…
Growth of Linear Perturbations in a Universe with Superfluid Dark Matter
Shreya Banerjee, Sayantani Bera, David F. Mota
The Lambda-Cold Dark Matter (LCDM) model agrees with most of the cosmological observations, but has some hindrances from observed data at smaller scales such as galaxies. Recently,…
Quantum nonlocality, and the end of classical space-time
Shreya Banerjee, Sayantani Bera, T. P. Singh
Quantum non-local correlations and the acausal, spooky action at a distance suggest a discord between quantum theory and special relativity. We propose a resolution for this discor…
Constraints on fourth order gravity from binary pulsar and gravitational waves
Shreya Banerjee, Sayantani Bera, Srimanta Banerjee +1
We have earlier proposed a fourth order gravity model as a possible explanation for late time cosmic acceleration, and for flattened galaxy rotation curves. The model has a free le…
Cosmological Constant, Quantum Measurement, and the Problem of Time
Shreya Banerjee, Sayantani Bera, Tejinder P. Singh
Three of the big puzzles of theoretical physics are the following: (i) There is apparently no time evolution in the dynamics of quantum general relativity, because the allowed quan…
