A Test of the Cosmological Principle with Quasars
Nathan Secrest, Sebastian von Hausegger, Mohamed Rameez +3
We study the large-scale anisotropy of the Universe by measuring the dipole in the angular distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wi…
A response to Rubin & Heitlauf: "Is the expansion of the universe accelerating? All signs still point to yes"
Jacques Colin, Roya Mohayaee, Mohamed Rameez +1
We have shown (Colin et al., 2019) that the acceleration of the Hubble expansion rate inferred from Type Ia supernovae (SNe Ia) is, at significance, a dipole approximately a…
Evidence for anisotropy of cosmic acceleration
Jacques Colin, Roya Mohayaee, Mohamed Rameez +1
Observations reveal a `bulk flow' in the local Universe which is faster and extends to much larger scales than is expected around a typical observer in the standard CDM cosmolog…
The dipole anisotropy of AllWISE galaxies
M. Rameez, R. Mohayaee, S. Sarkar +1
We determine the dipole in the WISE galaxy catalogue. After reducing star contamination to <0.1% by rejecting sources with high apparent motion and those close to the Galactic plan…
A single-merger scenario for the formation of the giant stream and the warp of M31
Raphael Sadoun, Roya Mohayaee, Jacques Colin
We propose that the accretion of a dwarf spheroidal galaxy provides a common origin for the giant southern stream and the warp of M31. We run about 40 full N-body simulations with…
M - sigma relation between SMBHs and the velocity dispersion of globular cluster systems
Raphael Sadoun, Jacques Colin
We find evidence that the mass MBH of central supermassive black holes (SMBHs) correlates with the velocity dispersion sigma_GC of globular cluster systems of their host galaxies.…
