Equivalence of mapping gravitational wave background anisotropy across bases at equal information content
Deepali Agarwal
Mapping anisotropies in the gravitational-wave background (GWB) requires choosing a basis to represent the sky intensity, such as pixel and spherical harmonic bases. Each introduce…
Efficient Search for Detection Candidates Using a Peak Finder Strategy for All-Sky-All-Frequency Gravitational Wave Radiometer
Arindam Sharma, Deepali Agarwal, Sanjit Mitra
The first all-sky-all-frequency (ASAF) radiometer search was conducted using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. The signifi…
Kinematic Anisotropies in PTA Observations: Analytical Toolkit
Maximilian Blümke, Kai Schmitz, Tobias Schröder +2
The reported evidence for an isotropic gravitational-wave background (GWB) from pulsar timing array (PTA) collaborations has motivated searches for extrinsic and intrinsic anisotro…
Source anisotropies and pulsar timing arrays
Bruce Allen, Deepali Agarwal, Joseph D. Romano +1
Pulsar timing arrays (PTA) hunt for gravitational waves (GW) by searching for the correlations that GWs induce in the time-of-arrival residuals from different pulsars. If the GW so…
