Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at with the 21-cm forest power spectrum
Tomáš Šoltinský, Arnab Chakraborty, Girish Kulkarni +10
Neutral regions of the intergalactic medium (IGM) during the Epoch of Reionization (EoR) remain largely unexplored due to the limitations of existing probes. Owing to discoveries o…
Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low
Anshuman Acharya, Satadru Bag, Sabrina Berger +29
The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…
Exploring biases in derived stellar parameters and the ionizing photon production efficiency
Ravi Jaiswar, Anshu Gupta, Elisabete da Cunha +8
Constraining the timescale and manner in which the Epoch of Reionization (EoR) occurred is a major JWST science goal. However, any constraints on the stellar or ionizing parameters…
SKA-Low simulations for a cosmic dawn/epoch of reionisation deep field
Anna Bonaldi, Philippa Hartley, Simon Purser +7
We present a realistic simulation of an SKA-Low cosmic dawn/epoch of reionisation (CD/EoR) observation, which can be used to further the development of foreground-mitigation approa…
Determining Ideal Fields for Epoch of Reionisation Science Using the 21 cm Line
E. Jong, C. Trott, C. D. Nunhokee +1
The upcoming Square Kilometre Array Low Frequency (SKA-Low) interferometer will have the required sensitivity to detect the 21 cm line from neutral hydrogen during the Epoch of Rei…
Evidence of Ultra-faint Radio Frequency Interference in Deep 21~cm Epoch of Reionization Power Spectra with the Murchison Widefield Array
Michael J. Wilensky, Miguel F. Morales, Bryna J. Hazelton +7
We present deep upper limits from the 2014 Murchison Widefield Array (MWA) Phase I observing season, with a particular emphasis on identifying the spectral fingerprints of extremel…
