NANOGrav Signal from the End of Inflation and the LIGO Mass and Heavier Primordial Black Holes
Amjad Ashoorioon, Kazem Rezazadeh, Abasalt Rostami
Releasing the 12.5-year pulsar timing array data, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently reported the evidence for a stochastic co…
Structure Formation in Dark Matter Particle Production Cosmology
Z. Safari, K. Rezazadeh, B. Malekolkalami
We investigate a cosmological scenario in which the dark matter particles can be created during the evolution of the Universe. By regarding the Universe as an open thermodynamic sy…
Mechanism of primordial black holes production and secondary gravitational waves in -attractor Galileon inflationary scenario
Zeinab Teimoori, Kazem Rezazadeh, Mariwan Ahmed Rasheed +1
We study the process of the Primordial Black Holes (PBHs) production in the novel framework, namely -attractor Galileon inflation (G-inflation) model. In our framework, we take…
Resurrecting the Power-law, Intermediate, and Logamediate Inflations in the DBI Scenario with Constant Sound Speed
Roonak Amani, Kazem Rezazadeh, Asrin Abdolmaleki +1
We investigate the power-law, intermediate, and logamediate inflationary models in the framework of DBI non-canonical scalar field with constant sound speed. In the DBI setting, we…
Brans-Dicke inflation in light of the Planck 2015 data
B. Tahmasebzadeh, K. Rezazadeh, K. Karami
We study inflation in the Brans-Dicke gravity as a special model of the scalar-tensor gravity. We obtain the inflationary observables containing the scalar spectral index, the tens…
