Assessing the potential of LIGO-India in resolving the Hubble tension
Kanchan Soni, Aditya Vijaykumar, Sanjit Mitra
Conclusive determination of the Hubble constant () is a major challenge in current astronomy due to the observed discrepancies between early and late universe measurements. Jo…
Profiling stellar environments of gravitational wave sources
Avinash Tiwari, Aditya Vijaykumar, Shasvath J. Kapadia +2
Gravitational waves (GWs) have enabled direct detections of compact binary coalescences (CBCs). However, their poor sky localisation and the typical lack of observable electromagne…
Gravitational-wave dark siren cosmology systematics from galaxy weighting
Alexandra G. Hanselman, Aditya Vijaykumar, Maya Fishbach +1
The detection of GW170817 and the measurement of its redshift from the associated electromagnetic counterpart provided the first gravitational wave determination of the Hubble cons…
Bounds on the charge of the graviton using gravitational wave observations
Sreejith Nair, Aditya Vijaykumar, Sudipta Sarkar
If the graviton possesses a non-zero charge , gravitational waves (GW) originating from astrophysical sources would experience an additional time delay due to intergalactic ma…
Consistent eccentricities for gravitational wave astronomy: Resolving discrepancies between astrophysical simulations and waveform models
Aditya Vijaykumar, Alexandra G. Hanselman, Michael Zevin
Detecting imprints of orbital eccentricity in GW signals promises to shed light on the formation mechanisms of binary black holes. To constrain formation mechanisms, distributions…
