Detecting Cosmic 21 cm Global Signal Using an Improved Polynomial Fitting Algorithm
Tianyang Liu, Junhua Gu, Quan Guo +3
Detecting the cosmic 21 cm signal from Epoch of Reionization (EoR) has always been a difficult task. Although the Galactic foreground can be regarded as a smooth power-law spectrum…
The Giant Radio Array for Neutrino Detection (GRAND) Collaboration -- Contributions to the 38th International Cosmic Ray Conference (ICRC 2023)
GRAND Collaboration, Rafael Alves Batista, Aurélien Benoit-Lévy +96
The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles of cosmic origin, with energies in excess of 100 PeV. GRAND uses la…
Mitigating the effect of 1/f noise on the detection of the HI intensity mapping power spectrum from single-dish measurements
Melis O. Irfan, Yichao Li, Mario G. Santos +5
We present and compare several methods to mitigate time-correlated (1/f) noise within the HI intensity mapping component of the MeerKAT Large Area Synoptic Survey (MeerKLASS). By s…
Global CD/EoR Signal Detection with a Dense Digital Beamforming Array and Beyond
Junhua Gu, Jingying Wang, Huanyuan Shan +5
The global neutral hydrogen 21 cm signal extracted from the all-sky averaged radio spectra is one of the signatures of the Cosmic Dawn and Epoch of Reionization (CD/EoR). The frequ…
Impact of the turnover in the high-z galaxy luminosity function on the 21-cm signal during Cosmic Dawn and Epoch of Reionization
Zekang Zhang, Huanyuan Shan, Junhua Gu +6
The shape of the faint-end of the high-z galaxy luminosity function (LF) informs early star formation and reionization physics during the Cosmic Dawn and Epoch of Reionization. Unt…
Direct Parameter Inference from Global EoR Signal with Bayesian Statistics
Junhua Gu, Jingying Wang
In the observation of sky-averaged HI signal from Epoch of Reionization, model parameter inference can be a computation-intensive work, which makes it hard to perform a direct one-…
