A star-forming galaxy at z=5.78 in the Chandra Deep Field South
Published 2003“…The large colour of (i′ - Z′)AB = 1.6 indicated a spectral break consistent with the Lyman α forest absorption shortward of Lyman α at z ≈ 6. …”

AN IONIZATION CONE IN THE DWARF STARBURST GALAXY NGC 5253
Published 2015“…The narrow morphology of the ionization cone supports the scenario that an orientation bias contributes to the difficulty in detecting Lyman continuum emission from starbursts and Lyman break galaxies.…”

The impact on cosmology of a primordial scaling field
Published 1998“…We briefly discuss the dynamics of such a scalar field and its impact on Big Bang nucleosynthesis, the growth of large scale structure and abundance of damped Lyman$-\alpha$ systems at high redshift. Given the simplicity of the model, its theoretical motivation, and its success in matching observations, we argue that it should be taken on par with other currently viable models of structure formation.…”

The impact of galactic feedback on the circumgalactic medium
Published 2015“…All our simulations produce the observed number of Damped Lyman α Absorbers. At lower column density, several of our simulations produce enough Lyman Limit Systems (LLS) 100 kpc from the galaxy, but in all cases the LLS abundance falls off with distance faster than observations, with too few LLS at 200 kpc. …”

Justifying and excusing young motherhood in Singapore
Published 2015“…Drawing on the perspectives of Goffman (1959, 1963) and Scott and Lyman (1968), this paper examines young mothers’ coping mechanisms – the way they justify and/or excuse their “deviant” behaviours and their negotiation of social norms to translate damaged identities into desirable ones.…”
