WebCross-correlating the data of neutral hydrogen (HI) 21cm intensity mapping with galaxy surveys is an effective method to extract astrophysical and cosmological information. In this work, we investigate the cross-correlation of MeerKAT single-dish mode HI intensity mapping and China Space Station Telescope (CSST) spectroscopic galaxy surveys. We …
Cosmology from a SKA HI intensity mapping survey
WebApr 14, 2024 · In this talk, we will report our recent progresses in probing the EoR with HI 21cm intensity mapping and Lyman-alpha forest. (1) The 21cm data analysis involves a series of steps including RFI flagging, foreground subtraction, and scientific interpretation. Towards future SKA observations, we develop new machine-learning-based tools for RFI ...

Experiments whose names are followed … WebJul 5, 2012 · Obtaining situational awareness of the post-event environment requires mapping the radiation distribution of the area and localization sources of high radioactive intensity. Conventional systems for these tasks require large, heavy, expensive equipment that necessitate the use of a full-size helicopter instead of an inexpensive, easily ... WebMay 1, 2024 · The HI intensity mapping technique consists of making maps of the brightness temperature of the sky at different frequencies. Since no other emission lines appear at these radio frequencies, there is a unique relation between observed frequency and redshift, ( 1 + z ) ν = ν HI = c ∕ λ HI , with λ HI = 21 cm the rest-frame wavelength of ... fitness gahanna ohio
