Hydrogen 21-cm Intensity Mapping at redshift 0.8
Tzu-Ching Chang, Ue-Li Pen, Kevin Bandura +1
Observations of 21-cm radio emission by neutral hydrogen at redshifts z ~ 0.5 to ~ 2.5 are expected to provide a sensitive probe of cosmic dark energy. This is particularly true ar…
The GMRT-EoR Experiment: A new upper limit on the neutral hydrogen power spectrum at z~8.6
Gregory Paciga, Tzu-Ching Chang, Yashwant Gupta +6
We present a new upper limit to the 21cm power spectrum during the Epoch of Reionization (EoR) which constrains reionization models with an unheated IGM. The GMRT-EoR experiment is…
AMiBA Wideband Analog Correlator
Chao-Te Li, Derek Y. Kubo, Warwick Wilson +27
A wideband analog correlator has been constructed for the Yuan-Tseh Lee Array for Microwave Background Anisotropy. Lag correlators using analog multipliers provide large bandwidth…
