Redshift Drift fluctuations from N-body simulations
Pedro Bessa, Valerio Marra, Tiago Castro
Measurements of the redshift drift -- the real time variation of the redshift of distance sources -- are expected in the next couple of decades using next generation facilities suc…

DUCA: Dynamic Universe Cosmological Analysis. II. The impact of clustering dark energy on the halo mass function
Tiago Castro, Stefano Borgani, Jeppe Dakin +3
Galaxy clusters are powerful probes of cosmology, and the halo mass function (HMF) serves as a fundamental tool for extracting cosmological information. Previous calibrations of th…
