Reconstructing the kinematics of Laniakea using Type Ia Supernovae
Francesco Sorrenti, Erick Pastén, Leonardo Giani
We develop a kinematic framework that relates the monopole, dipole, and quadrupole of the luminosity distance to an ellipsoidal peculiar velocity field describing the dynamics of t…
Skipping the rungs! Calibrating distance indicators through their clustering with galaxies
Madeline L. Cross-Parkin, Leonardo Giani, Cullan Howlett +1
We show that angular cross-correlations between distance indicators and galaxy redshift catalogues, when interpreted within an assumed cosmological model, can constrain potential b…
Dark siren cross-correlations and the sensitivity of to methodological choices
Madeline L. Cross-Parkin, Cullan Howlett, Leonardo Giani +2
Gravitational wave sources act as absolute distance indicators, making them powerful probes of the present-day expansion rate of the Universe, . The cross-correlation method c…
The velocity coherence scale: a novel probe of cosmic homogeneity and a potential standard ruler
Leonardo Giani, Cullan Howlett, Chris Blake +2
We introduce the velocity coherence scale , the scale at which the spherical volume average of the trace of the velocity correlation tensor transitions from scaling faster tha…
