Peering Towards Cosmic Dawn Edited By IAU IAU Symposium Proceedings of the International Astronomical Union IAU Symposium No. 333 Symposium 2–6 October 2017 Several Epoch of Reionization (EoR) experiments, for example, LOFAR, MWA and PAPER, are currently under way and producing 333 Dubrovnik, Croatia results. These very deep observations not only set constraints on when and where the fi rst sources formed in the early Universe and began (re)ionizing the predominantly neutral all-pervasive intergalactic medium, but they also provide high-quality data for 2–6 October 2017 333 Peering towards 2–6 October 2017 cutting edge auxiliary foreground science. Obviously studying the Dubrovnik, Croatia Cosmic Dawn physical origin of the foreground emission, whether Galactic or Dubrovnik, Croatia Peering towards extragalactic, is a very exciting fi eld in its own right and is of fundamental importance for perfecting the foreground removal techniques in the cosmological experiments. These proceedings Cosmic Dawn of IAU S333 address both topics through giving the clearest and widest possible view on the EoR; presenting the state-of-the-art foreground science; and discussing challenges of upcoming and planned radio facilities such as HERA and SKA. Proceedings of the International Astronomical Union Editor in Chief: Dr Piero Benvenuti This series contains the proceedings of major scientifi c meetings held by the International Astronomical Union. Each volume contains a series of articles on a topic of current interest in astronomy, giving a timely overview of research in the fi eld. With contributions by leading scientists, these books are at a level suitable for research astronomers and graduate students.

  • Chapter 6 Foregrounds and Their Mitigation
    Chapter 6 Foregrounds and their mitigation1 Emma Chapman (Imperial College London) Vibor Jelic´ (Ruder Boskoviˇ c´ Institute) Abstract The low-frequency radio sky is dominated by the diffuse synchrotron emis- sion of our Galaxy and extragalactic radio sources related to Active Galactic Nuclei and star-forming galaxies. This foreground emission is much brighter than the cosmological 21 cm emission from the Cosmic Dawn and Epoch of Reionization. Studying the physical properties of the foregrounds is therefore of fundamental importance for their mitigation in the cosmological 21 cm ex- periments. This chapter gives a comprehensive overview of the foregrounds and our current state-of-the-art knowledge about their mitigation. 6.1 What are the foregrounds? A detection of the redshifted 21 cm emission from the Cosmic Dawn (CD) and Epoch of Reionization (EoR) is a daunting task due to a number of chal- lenges, which are different in nature and complexity. One of them is the extremely prominent foreground emission, which dominates the sky at low arXiv:1909.12369v1 [astro-ph.CO] 26 Sep 2019 radio frequencies. This emission intervenes like fog on an autumn morning and obscures our view towards the neutral hydrogen regions from the times of the first “stars” in the Universe. To clear the view and to make the detec- tion possible, we need to study the foreground emission in great detail and 1To appear as a book chapter in “The Cosmic 21-cm Revolution: Charting the first billion years of our Universe”, Ed.

Mul- tiple methods of modelling these foregrounds with varying levels of assumption have been trialled and shown promising recoveries on simulated data. Recently however there has been increased discussion of using the expected shape of the foregrounds in Fourier space to define an EoR window free of foreground contamination. By carrying out analysis within this window only, one can avoid the foregrounds and any statis- tical bias they might introduce by instead removing these foregrounds. In this paper we discuss the advantages and disadvantages of both foreground removal and fore- ground avoidance. We create a series of simulations with noise levels in line with both current and future experiments and compare the recovered statistical cosmological signal from foreground avoidance and a simplified, frequency independent foreground removal model.

Whereas IR detections have been made of sources (Ly- emitters, quasars and drop-outs) in this redshift regime, in relatively small fields of view, no direct detection of neutral hydrogen via the redshifted 21-cm line has yet been established. Such a direct detection is expected in the coming years with ongoing surveys and will open up the entire universe from z 6-200 for astrophysical Ø and cosmological studies, opening not only the EoR, but also its preceding Cosmic Dawn (z 40-15) and possibly even the later phases of the Dark Ages (z 200-40), leaving Ø Ø only the “Age of Ignorance” (z 1100-200) inaccessible to astronomers. All currently Ø ongoing experiments attempt statistical detections of the 21-cm signal during the EoR, with limited signal-tonoise. Direct imaging, except maybe on the largest (degree) scales at lower redshift, will remain out of reach. The Square Kilometre Array (SKA), however, will revolutionize the field, and allow direct imaging of neutral hydrogen from scales of arc-minutes to degrees over most of the redshift range z 6-30.

The EoR foregrounds can be up to three magnitudes greater than the cosmolog- ical signal we wish to detect. Multiple methods have been developed in order to extract the cosmological signal, falling roughly into three categories: foreground removal, foreground sup- pression and foreground avoidance. These main approaches are briefly discussed in this review and consideration taken to the future application of these methods as a multi-layered approach. Keywords. methods: data analysis, methods: statistical, telescopes, radio continuum: general, cosmology: observations, (cosmology:) early universe 1. Introduction The first direct detection of the Epoch of Reionization is a challenge on many fronts, not least of them the removal of the foregrounds. The astrophysical foregrounds in an EoR ex- periment are expected to consist of bright compact sources, diffuse Galactic Synchrotron, diffuse Galactic free-free and extragalactic foregrounds. While other foregrounds such as radio recombination lines (e.g. Gleser, Nusser & Benson. (2008)) and RFI (e.g. Offringa, van de Gronde & Roerdink (2012)) of course exist they are thought to be easily identifi- able and removable and are not dealt with under the umbrella of foreground mitigation methods.
