High accuracy post-Newtonian and numerical relativity comparisons involving higher modes for eccentric binary black holes and a dominant mode eccentric inspiral-merger-ringdown model

Abhishek Chattaraj, Tamal RoyChowdhury, Divyajyoti +2

Spherical harmonic modes of gravitational waveforms for inspiraling compact binaries in eccentric orbits from post-Newtonian (PN) theory accurate to third post-Newtonian order, and…

All-sky Searches for Continuous Gravitational Waves from Isolated Neutron Stars in the Data from the First Part of the Fourth LIGO-Virgo-KAGRA Observing Run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1826

We present results from an all-sky search for continuous gravitational waves, using three different methods applied to the first eight months of LIGO data from the fourth LIGO-Virg…

Open Data from LIGO, Virgo, and KAGRA through the First Part of the Fourth Observing Run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1768

LIGO, Virgo, and KAGRA form a network of gravitational-wave observatories. Data and analysis results from this network are made publicly available through the Gravitational Wave Op…

Blind spots and biases: the dangers of ignoring eccentricity in gravitational-wave signals from binary black holes

Divyajyoti, Sumit Kumar, Snehal Tibrewal +2

Most gravitational wave (GW) events observed by the LIGO and Virgo detectors are consistent with mergers of binary black holes (BBHs) on quasi-circular orbits. However, some events…

Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…

A search using GEO600 for gravitational waves coincident with fast radio bursts from SGR 1935+2154

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780

The magnetar SGR 1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935+2154 were first detected by CHIME/FRB and STARE2 in 2020 April, after t…
