LOFAR as a Probe of Cosmological Reionisation
نویسندگان
چکیده
We propose use of the thickness of the ionisation front as a discriminant between alternative modes of reionisation in the early universe, by stars or by miniquasars. This will enable LOFAR to play an important role since the expected angular resolution is sensitive to scales that correspond to the transition between ionised and neutral regions for hard sources of ionising photons.

LOFAR as a Probe of the Sources of Cosmological Reionisation
We propose use of the thickness of the ionisation front as a discriminant between alternative modes of reionisation in the early universe, by stars or by miniquasars. Assuming a photoionisation-recombination balance, we find that for miniquasar sources the transition from neutral to ionised intergalactic medium is extended and has two features. The first is a sudden steep increase in the neutra...
متن کاملLOFAR - Opening up a new window on the Universe
LOFAR, the Low Frequency Array, is a next-generation radio telescope that is being built in Northern Europe and expected to be fully operational at the end of this decade. It will operate at frequencies from 15 to 240 MHz (corresponding to wavelengths of 20 to 1.2 m). Its superb sensitivity, high angular resolution, large field of view and flexible spectroscopic capabilities will represent a dr...
متن کاملBiased Reionisation and Non-Gaussianity in Redshifted 21cm Intensity Maps of the Reionisation Epoch
Spatial dependence in the statistics of redshifted 21cm fluctuations promises to provide the most powerful probe of the reionisation epoch. In this paper we consider the second and third moments of the redshifted 21cm intensity distribution using a simple model that accounts for galaxy bias during the reionisation process. We demonstrate that skewness in redshifted 21cm maps should be substanti...
متن کاملLOFAR, a new low frequency radio telescope
LOFAR, the Low Frequency Array, is a large radio telescope consisting of approximately 100 soccer-field sized antenna stations spread over a region of 400 km in diameter. It will operate at frequencies from ∼ 10 to 240 MHz, with a resolution at 240 MHz of better than an arcsecond. Its superb sensitivity will allow for studies of a broad range of astrophysical topics, including reionisation, tra...
متن کاملThe effect of reionisation on the CMB–density correlation
In this paper we show how the rescattering of CMB photons after cosmic reionisation can give a significant linear contribution to the temperature–matter cross-correlation measurements. These anisotropies, which arise via a late time Doppler effect, are on scales much larger than the typical scale of non-linear effects at reionisation; they can contribute to degree scale cross-correlations and c...
