Improved gravitational-wave constraints on higher-order curvature theories of gravity
Scott E. Perkins, Remya Nair, Hector O. Silva +1
Gravitational wave observations of compact binaries allow us to test general relativity (and modifications thereof) in the strong and highly-dynamical field regime of gravity. Here…
Improved binary pulsar constraints on the parameterized post-Einsteinian framework
Remya Nair, Nicolás Yunes
The parameterized post-Einsteinian formalism was developed to search for generic deviations from general relativity with gravitational waves. We here present constraints on this fr…
Fundamental physics implications on higher-curvature theories from the binary black hole signals in the LIGO-Virgo Catalog GWTC-1
Remya Nair, Scott Perkins, Hector O. Silva +1
Gravitational-wave astronomy offers not only new vistas into the realm of astrophysics, but it also opens an avenue for probing, for the first time, general relativity in its stron…
Synergy between ground and space based gravitational wave detectors II: Localisation
Remya Nair, Takahiro Tanaka
We study the advantage of combining measurements from future ground and space based gravitational wave detectors in estimating the parameters of a black-hole binary coalescence. Th…
Measuring the Hubble constant: Gravitational wave observations meet galaxy clustering
Remya Nair, Sukanta Bose, Tarun Deep Saini
We show how the distances to binary black holes measured in gravitational wave observations with ground-based interferometers can be used to constrain the redshift-distance relatio…
Synergy between ground and space based gravitational wave detectors for estimation of binary coalescence parameters
Remya Nair, Sanjay Jhingan, Takahiro Tanaka
We study the advantage of the co-existence of future ground and space based gravitational wave detectors, in estimating the parameters of a binary coalescence. Using the post-Newto…
Testing the consistency between cosmological measurements of distance and age
Remya Nair, Sanjay Jhingan, Deepak Jain
We present a model independent method to test the consistency between cosmological measurements of distance and age, assuming the distance duality relation. We use type Ia supernov…
Observational cosmology and the cosmic distance-duality relation
S Jhingan, D Jain, R Nair
We study the validity of cosmic distance duality relation between angular diameter and luminosity distances. To test this duality relation we use the latest Union2 Supernovae Type…
Exploring scalar field dynamics with Gaussian processes
Remya Nair, Sanjay Jhingan, Deepak Jain
The origin of the accelerated expansion of the Universe remains an unsolved mystery in Cosmology. In this work we consider a spatially flat Friedmann-Robertson-Walker (FRW) Univers…
Is dark energy evolving?
Remya Nair, Sanjay Jhingan
We look for evidence for the evolution in dark energy density by employing Principal Component Analysis (PCA). Distance redshift data from supernovae and baryon acoustic oscillatio…
Cosmic distance duality and cosmic transparency
Remya Nair, Sanjay Jhingan, Deepak Jain
We compare distance measurements obtained from two distance indicators, Super- novae observations (standard candles) and Baryon acoustic oscillation data (standard rulers). The Uni…
Cosmokinetics: A joint analysis of Standard Candles, Rulers and Cosmic Clocks
Remya Nair, Sanjay Jhingan, Deepak Jain
We study the accelerated expansion of the universe by using the kinematic approach. In this context, we parameterize the deceleration parameter, q(z), in a model independent way. A…
Observational Cosmology And The Cosmic Distance Duality Relation
Remya Nair, Sanjay Jhingan, Deepak Jain
We study the validity of cosmic distance duality relation between angular diameter and luminosity distances. To test this duality relation we use the latest Union2 Supernovae Type…
Binary Pulsar Constraints on the Parameterized post-Einsteinian Framework
Nicolas Yunes, Scott A. Hughes
We constrain the parameterized post-Einsteinian framework with binary pulsar observations of orbital period decay due to gravitational wave emission. This framework proposes to enh…
