Testing No slip model with pulsar timing arrays: NANOGrav and IPTA
Mohammadreza Davari, Alireza Allahyari, Shahram Khosravi
We perform an observational study of modified gravity considering a potential inflationary interpretation of pulsar timing arrays (PTA). We use a motivated model known as no slip i…
Perturbation level interacting dark energy model and its consequence on late-time cosmological parameters
Mahnaz Asghari, Shahram Khosravi, Amir Mollazadeh
In the present paper, we study the capability of interacting dark energy model with pure momentum transfer in the dark sector to reconcile tensions between low redshift observation…
On structure formation from a small-scales-interacting dark sector
Mahnaz Asghari, Jose Beltran Jimenez, Shahram Khosravi +1
We consider a cosmological model with an interaction between dark matter and dark energy which leaves the background cosmology unaffected and only affects the evolution of the pert…
21-cm power spectrum and ionization bias as a probe of long-mode modulated non Gaussian sky
Shahram Khosravi, Amirabbas Ghazizadeh, Shant Baghram
The observed hemispherical power asymmetry in cosmic microwave background radiation can be explained by long wavelength mode (long-mode) modulation. In this work we study the prosp…
ISW-Galaxy Cross Correlation:A probe of Dark Energy clustering and distribution of Dark Matter tracers
Shahram Khosravi, Amir Mollazadeh, Shant Baghram
Cross correlation of the Integrated Sachs-Wolfe signal (ISW) with the galaxy distribution in late time is a promising tool for constraining the dark energy properties. Here, we stu…
Simultaneous effect of Modified Gravity and Primordial Non-Gaussianity in Large Scale Structure Observations
Nareg Mirzatuny, Shahram Khosravi, Shant Baghram +1
In this work we study the simultaneous effect of primordial non-Gaussianity and the modification of the gravity in framework on large scale structure observations. We show t…
