Discovery of a Methane Dwarf from the Ifa-deep Survey

We present the discovery of a distant methane dwarf, the first from the Institute for Astronomy (IfA) Deep Survey. The object (“IfA 0230-Z1”) was identified from deep optical I and z-band imaging, being conducted as an IfA-wide collaboration using the prime-focus imager Suprime-Cam on the Subaru 8.2-m Telescope. IfA 0230-Z1 is extremely red in the IzJ (0.8–1.2 μm) bands but relatively blue in J...

High Redshift Supernova Rates

We use a sample of 42 supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope as part of the Great Observatories Origins Deep Survey to measure the rate of core collapse supernovae to z ∼ 0.7 and type Ia supernovae to z ∼ 1.6. This significantly increases the redshift range where supernova rates have been estimated from observations. The rate of core collaps...

SNLS – the Supernova Legacy Survey

Type Ia supernovae (SNeIa) provide direct evidence for an accelerating universe, and for the existence of " dark energy " driving this expansion. The Supernova Legacy Survey (SNLS) will deliver many hundreds of SNIa detections, and well-sampled g ′ r ′ i ′ z ′ light curves, over the next 5 years. Using these data, we will obtain a precise measurement of the cosmological parameters (Ω mass , Ω Λ...

The Evolution of the Cosmic Supernova Rates

Through a combination of deep wideeld imaging and near-IR spectroscopy, the NGST will be able to chart with unprecedented accuracy the evolution of cosmic structures after the `dark ages' (z < 5), when galaxies are thought to assemble and form the bulk of their stars. In particular, accurate measurements at all redshifts of the frequencies of Type II and Ia SNe could be used as a probe of the s...
