Determining the primordial helium abundance and UV background using fluorescent emission in star-free dark matter haloes
Calvin Sykes, Michele Fumagalli, Ryan Cooke +1
Observational measures of the primordial helium mass fraction, , are of interest for cosmology and fundamental particle physics. Current measures obtained from H II regi…
Gas filaments of the cosmic web located around active galaxies in a proto-cluster
H. Umehata, M. Fumagalli, I. Smail +15
Cosmological simulations predict the Universe contains a network of intergalactic gas filaments, within which galaxies form and evolve. However, the faintness of any emission from…
Fluorescent rings in star-free dark matter haloes
Calvin Sykes, Michele Fumagalli, Ryan Cooke +2
Photoheating of the gas in low-mass dark matter (DM) haloes prevents baryons from cooling, leaving the haloes free of stars. Gas in these 'dark' haloes remains exposed to the ultra…
The Cosmic Lens All-Sky Survey:II. Gravitational lens candidate selection and follow-up
I. W. A. Browne, P. N. Wilkinson, N. J. F. Jackson +19
We report the final results of the search for gravitationally lensed flat-spectrum radio sources found in the combination of CLASS (Cosmic Lens All Sky Survey) and JVAS (Jodrell-Ba…
The Cosmic Lens All-Sky Survey: I. Source selection and observations
S. T. Myers, N. J. Jackson, I. W. A. Browne +15
The Cosmic Lens All-Sky Survey (CLASS) is an international collaborative program which has obtained high-resolution radio images of over 10000 flat-spectrum radio sources in order…
