Dipole Anisotropy in Newly Sampled AGN Population: Still in Tension with CMB Dipole
Dahee Lee, Minji Oh, Gayathri Asok +2
We revisit the all-sky survey data, the Wide-field Infrared Survey Explorer (WISE) catalog, with an improved galaxy-selection criterion to investigate the inconsistency between the…
Cosmological Implication of Cross-correlation between Galaxy Clustering and 21-cm Line Intensity Mapping
Yong-Seon Song, Minji Oh, Kyungjin Ahn +1
The apparent anisotropies of galaxy clustering and 21-cm mapping in redshift space offer a unique opportunity to simultaneously probe cosmic expansion and gravity on cosmological s…
Double-Peaked Ly Emission during Reionization Requires Nearby Voids and a Favorable Local Ionizing Background
Hyunbae Park, Aaron Smith, Intae Jung +11
Several Lyman-alpha (Ly) emitters deep into the reionization era exhibit double-peaked Ly emission profiles, raising the question of how the intergalactic medium can transm…
Kinematically induced dipole anisotropy in line-emitting galaxy number counts and line intensity maps
Kyungjin Ahn
The motion of the solar system against an isotropic radiation background, such as the cosmic microwave background, induces a dipole anisotropy in the background due to the Doppler…
