Circumventing Cosmic Variance via Remote Quadrupole Measurements
Arsalan Adil, Reid Koutras, Emory F. Bunn
A number of important cosmological questions can be addressed only by probing perturbation modes on the largest accessible scales. One promising probe of these modes is the Kamionk…

Simulating Partial Sky Cosmic Microwave Background Maps with 3D Fast Fourier Transforms
Mariona Giner Mascarell, Emory F. Bunn
Simulated maps of the microwave background (CMB) radiation are generally created using one of two methods: all-sky simulations use the spherical harmonic transform, while maps cove…

Reassessment of the dipole in the distribution of quasars on the sky
Arefe Abghari, Emory F. Bunn, Lukas T. Hergt +4
We investigate recent claims by Secrest et al. of an anomalously large amplitude of the dipole in the distribution of CatWISE-selected quasars on the sky. Two main issues indicate…
