CMB Bounds on Primordial Black Holes via Radiation Capture
Marzieh Farhang, S. M. S. Movahed
We explore the capture of neutrinos and photons in the cosmic neutrino and photon background by primordial black holes (PBHs). We model this phenomenon as a gravitational interacti…
Compact Binary Merger Rate with Modified Gravity in Dark-Matter Spikes
Saeed Fakhry, Sara Gholamhoseinian, Marzieh Farhang
In this study, we investigate the impact of modified gravity on the merger rate of compact binaries within dark-matter spikes surrounding super-massive black holes (SMBHs). Specifi…
In-Flight Performance of Spider's 280 GHz Receivers
Elle C. Shaw, P. A. R. Ade, S. Akers +84
SPIDER is a balloon-borne instrument designed to map the cosmic microwave background at degree-angular scales in the presence of Galactic foregrounds. SPIDER has mapped a large sky…
A Semiblind Reconstruction of the History of Effective Number of Neutrinos Using CMB Data
Sarah Safi, Marzieh Farhang, Olga Mena +1
We explore the possibility of redshift-dependent deviations in the contribution of relativistic degrees of freedom to the radiation budget of the cosmos, conventionally parameteriz…
Primordial Black Hole-Neutron Star Merger Rate in Modified Gravity
Saeed Fakhry, Maryam Shiravand, Marzieh Farhang
In this work we investigate the merger rate of primordial black hole-neutron star (PBH-NS) binaries in two widely-studied modified gravity (MG) models: Hu-Sawicki gravity an…
Sensitivity of Cosmological Parameter Estimation to Nonlinear Prescription from Cosmic Shear
Sarah Safi, Marzieh Farhang
Several ongoing and upcoming large scale structure surveys aim to explore the nonlinear regime of structure formation with high precision. Making reliable cosmological inferences f…
