Generic EFT-motivated beyond General Relativity gravitational wave tests and their curvature dependence: from observation to interpretation
Laura Bernard, Suvendu Giri, Luis Lehner +1
We present a "dictionary" to expedite the identification of potential deviations in gravitational waveforms from those predicted by General Relativity (GR) during the inspiral phas…
Wheeler-DeWitt equation and the late gravitational collapse: effects of factor ordering and the tunneling scenario
Davide Batic, Marek Nowakowski, Neelima Govind Kelkar
We set up the Wheeler-DeWitt (WDW) equation for late gravitational collapse. The fact that the gravitational collapse and the expanding/ collapsing universe can be described within…
The Universe according to DESI results
Davide Batic, Sergio Bravo Medina, Marek Nowakowski
The recent fit of cosmological parameters by the Dark Energy Spectroscopic Instrument (DESI) collaboration will have a significant impact on our understanding of the universe. Give…
Cosmologies in theory with non-minimal coupling between geometry and matter
Sergio Bravo Medina, Marek Nowakowski, Ronaldo V. Lobato +1
Among the recent extensions to standard General Relativity, gravity has risen an interest given the possibility of coupling between geometry and matter. We exa…
Gravitational Collapse via Wheeler-DeWitt Equation
Davide Batic, Marek Nowakowski
We analyze the Wheeler-DeWitt (WDW) equation in the context of a gravitational collapse. The physics of an expanding/collapsing universe and many details of a collapsing star can c…
A comment on singular and non-singular black holes using the Gaussian distribution
D. Batic, M. Nowakowski, S. A. Salim
In this work, we join the controversial discussion on singular and non-singular black holes using the Gaussian distribution. Our result which uses correct boundary conditions shift…
Axisymmetric Solutions to Einstein Field Equations via Integral Transforms
D. Batic, N. B. Debru, M. Nowakowski
In this paper, we present new axisymmetric and reflection symmetric vacuum solutions to the Einstein field equations. They are obtained using the Hankel integral transform method a…
Luminosity distance uncertainties from gravitational wave detections by third generation observatories
Josiel Mendonça Soares de Souza, Riccardo Sturani
A new generation of terrestrial gravitational wave detectors is currently being planned for the next decade, and it is expected to detect most of the coalescences of compact object…
Probing Ultralight Bosons with Binary Black Holes
Daniel Baumann, Horng Sheng Chia, Rafael A. Porto
We study the gravitational-wave (GW) signatures of clouds of ultralight bosons around black holes (BHs) in binary inspirals. These clouds, which are formed via superradiance instab…
All-sky search for long-duration gravitational wave transients in the first Advanced LIGO observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +990
We present the results of a search for long-duration gravitational wave transients in the data of the LIGO Hanford and LIGO Livingston second generation detectors between September…
Effects of Data Quality Vetoes on a Search for Compact Binary Coalescences in Advanced LIGO's First Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +957
The first observing run of Advanced LIGO spanned 4 months, from September 12, 2015 to January 19, 2016, during which gravitational waves were directly detected from two binary blac…
Gravitational waves from neutron star excitations in binary inspirals
A. Parisi, R. Sturani
In the context of binary inspiral of mixed neutron star - black hole systems, we investigate the excitation of the neutron star oscillation modes by the orbital motion. We study ge…
Radiation reaction for spinning bodies in effective field theory II: Spin-spin effects
Natália T. Maia, Chad R. Galley, Adam K. Leibovich +1
We compute the leading Post-Newtonian (PN) contributions at quadratic order in the spins to the radiation-reaction acceleration and spin evolution for binary systems, entering at f…
Radiation reaction for spinning bodies in effective field theory I: Spin-orbit effects
Natália T. Maia, Chad R. Galley, Adam K. Leibovich +1
We compute the leading Post-Newtonian (PN) contributions at linear order in the spin to the radiation-reaction acceleration and spin evolution for binary systems, which enter at fo…
The Lamb shift and the gravitational binding energy for binary black holes
Rafael A. Porto
We show that the correction to the gravitational binding energy for binary black holes due to the tail effect resembles the Lamb shift in the Hydrogen atom. In both cases a 'conser…
On the Apparent Ambiguities in the Post-Newtonian Expansion for Binary Systems
Rafael A. Porto, Ira Z. Rothstein
We discuss the source of the apparent ambiguities arising in the calculation of the dynamics of binary black holes within the Post-Newtonian framework. Divergences appear in both t…
Directional limits on persistent gravitational waves from Advanced LIGO's first observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +993
We employ gravitational-wave radiometry to map the gravitational waves stochastic background expected from a variety of contributing mechanisms and test the assumption of isotropy…

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +992
A wide variety of astrophysical and cosmological sources are expected to contribute to a stochastic gravitational-wave background. Following the observations of GW150914 and GW1512…
