The Impact of Line Misidentification on Cosmological Constraints from Euclid and other Spectroscopic Galaxy Surveys
G. E. Addison, C. L. Bennett, D. Jeong +2
We perform forecasts for how baryon acoustic oscillation (BAO) scale and redshift-space distortion (RSD) measurements from future spectroscopic emission line galaxy (ELG) surveys s…
Position-dependent power spectra of the 21-cm signal from the epoch of reionization
Sambit K. Giri, Anson D'Aloisio, Garrelt Mellema +3
The 21-cm signal from the epoch of reionization is non-Gaussian. Current radio telescopes are focused on detecting the 21-cm power spectrum, but in the future the Square Kilometre…
Unbiased Cosmological Parameter Estimation from Emission Line Surveys with Interlopers
Henry S. Grasshorn Gebhardt, Donghui Jeong, Humna Awan +11
The galaxy catalogs generated from low-resolution emission line surveys often contain both foreground and background interlopers due to line misidentification, which can bias the c…
Delta-map method to remove CMB foregrounds with spatially varying spectra
Kiyotomo Ichiki, Hiroaki Kanai, Nobuhiko Katayama +1
We extend the internal template foreground removal method by accounting for spatially varying spectral parameters such as the spectral indices of synchrotron and dust emission and…
Cool core disturbed: Observational evidence for coexistence of sub-sonic sloshing gas and stripped shock-heated gas around the core of RX J1347.5-1145
Shutaro Ueda, Tetsu Kitayama, Masamune Oguri +13
RXJ1347.5-1145 (z = 0.451) is one of the most luminous X-ray galaxy clusters, which hosts a prominent cool core and exhibits a signature of a major merger. We present the first dir…
Operations on integral lifts of K(n)
Jack Morava
This very rough sketch is a sequel to arXiv:1808.08587; it presents evidence that operations on lifts of the functors K(n) to cohomology theories with values in modules over valuat…
