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…
An effective -Szekeres modelling of the local Universe with Cosmicflows-4
Marco Galoppo, Leonardo Giani, Morag Hills +1
We develop an effective description of the local cosmic environment, namely, for redshift , to quantify the bias induced by local structure on cosmological observab…
The matter with(in) CPL
Leonardo Giani, Rodrigo Von Marttens, Oliver Fabio Piattella
We introduce a two-parameter phenomenological extension of the CDM model in which the equation of state parameter of the ``dust'' fluid becomes different from zero for redshifts…
