The Galaxy Number Density Profile of Halos by Fei Qin, David Parkinson, Adam R. H. Stevens, Cullan Howlett

“…More precise measurements of galaxy clustering will be provided by the next generation of galaxy surveys, such as DESI, WALLABY, and the Square Kilometre Array. To utilize this information to improve our understanding of the Universe, we need to accurately model the distribution of galaxies in their host dark matter halos. …”

Reionization and beyond: detecting the peaks of the cosmological 21 cm signal by Mesinger, Andrei, Ewall-Wice, Aaron Michael, Hewitt, Jacqueline N

“…For each parameter combination, we compute the signal-to-noise ratio (S/N) of the large-scale (k similar to 0.1 Mpc(-1)) 21 cm power for both reionization and X-ray heating for a 2000 h observation with several instruments: 128 tile Murchison Wide Field Array (MWA128T), a 256 tile extension (MWA256T), the Low Frequency Array (LOFAR), the 128 element Precision Array for Probing the Epoch of Reionization (PAPER), and the second-generation Square Kilometre Array (SKA). We show that X-ray heating and reionization in many cases are of comparable detectability. …”
