Euclid: Measuring the intrinsic alignment of galaxies around cosmic voids in the \Euclid Flagship simulation\
P. Vielzeuf, M. -C. Cousinou, A. Pisani +149
We present a methodology to measure the intrinsic alignment (IA) signal of galaxies in the vicinity of cosmic voids using the \Euclid-like Flagship cosmological simulation from the…
Integrated Sachs-Wolfe maps from the Gower Street CDM simulations
Mina Ghodsi Yengejeh, András Kovács, István Szapudi +1
The late-time linear Integrated Sachs-Wolfe (ISW) effect directly probes the dynamics of cosmic acceleration and the nature of dark energy. Detecting these weak, secondary temperat…
A Multi-Probe ISW Study of Dark Energy Models with Negative Energy Density: Galaxy Correlations, Lensing Bispectrum, and Planck ISW-Lensing Likelihood
Payam Ghafari, Mahdi Najafi, Mina Ghodsi Yengejeh +3
We investigate the late-time imprints of three dark energy (DE) models, namely, the Chevallier-Polarski-Linder (CPL) parametrization, CDM, and an Omnipotent DE model, on…
Compact Binary Merger Rate in Dark-Matter Spikes
Saeed Fakhry, Zahra Salehnia, Azin Shirmohammadi +2
Nowadays, the existence of supermassive black holes (SMBHs) in the center of galactic halos is almost confirmed. An extremely dense region referred to as dark-matter spike is expec…
The Integrated Sachs-Wolfe Effect in Interacting Dark Matter-Dark Energy Models
Mina Ghodsi Yengejeh, Saeed Fakhry, Javad T. Firouzjaee +1
Interacting dark matter-dark energy (IDMDE) models can be taken to account as one of the present challenges that may affect the cosmic structures. In this work, we study the integr…
