An 80-kpc Ly alpha halo around a high-redshift type-2 quasi-stellar object
We announce the discovery of an extended emission line region associated with a high redshift type-2 QSO. The halo, which was discovered in our new wide-field narrow-band survey, resides at z = 2.85 in the Spitzer First ...
Infrared and millimetre-wavelength evidence for cold accretion within a z = 2.83 Lyman-alpha blob
This paper discusses infrared and millimetre-wavelength observations of a Lyman alpha blob (LAB) discovered by Smith & Jarvis, a candidate for ionization by the cold accretion scenario discussed in Fardal et al. and Dijkstra ...
Evidence for cold accretion onto a massive galaxy at high redshift ?
In this Letter we report on the discovery of a z = 2.83 Lyman alpha Blob (LAB) found in our wide-field narrow-band survey within the Spitzer First Look Survey region. The blob is extended over at least 95 kpc and has a ...
