Cosmological information in the redshift-space bispectrum
Victoria Yankelevich, Cristiano Porciani
We use the Fisher-matrix formalism to investigate whether the galaxy bispectrum in redshift space, , contains additional cosmological information with respect to the power spect…
The halo bispectrum as a sensitive probe of massive neutrinos and baryon physics
Victoria Yankelevich, Ian G. McCarthy, Juliana Kwan +2
The power spectrum has been a workhorse for cosmological studies of large-scale structure. However, the present-day matter distribution is highly non-Gaussian and significant cosmo…
Notes on counter-orbiting globular clusters in the Milky Way
Victoria Yankelevich
It is argued that Galactic globular clusters rotating retrograde may originate from prograde globular clusters that change their angular momenturm due to gravitational perturbation…
The SPace-based InterFerometer Feasibility (SPIFF) Project: Enabling Future High-Resolution Astronomy Across the EM Spectrum
Berke Vow Ricketti, Victoria Yankelevich, Chris Benson +19
A plethora of astronomical science cases can only be achieved with high angular resolution observations, and we can expect the number of these to grow as astronomers are constraine…
The reach of next-to-leading-order perturbation theory for the matter bispectrum
Davit Alkhanishvili, Cristiano Porciani, Emiliano Sefusatti +4
We provide a comparison between the matter bispectrum derived with different flavours of perturbation theory at next-to-leading order and measurements from an unprecedentedly large…
Towards accurate rescaling of a halo mass function
Victoria Yankelevich, Sergey Pilipenko
We investigate the precision within which a simulated dark matter halo mass function can be rescaled to a different set of cosmological parameters. Our tests show that the accuracy…
