Abstract:
The Type Ia supernova (SN Ia) rate, when compared to the cosmic star
formation history (SFH), can be used to derive the delay-time
distribution (DTD; the hypothetical SN Ia rate versus time following a
brief burst of star formation) of SNe Ia, which can distinguish among
progenitor models. We present the results of a supernova (SN) survey
in the Subaru Deep Field (SDF). Over a period of 3 years, we have
observed the SDF on four independent epochs with Suprime-Cam on the
Subaru 8.2-m telescope, with two nights of exposure per epoch, in the
R, i' and z' bands. We have discovered 150 SNe out to redshift z~=2.
Using 11 photometric bands from the observer-frame far-ultraviolet
to the near-infrared, we derive photometric redshifts for the SN host
galaxies (for 24 we also have spectroscopic redshifts). This
information is combined with the SN photometry to determine the type
and redshift distribution of the SN sample. Our final sample includes
28 SNe Ia in the range 1.0<z<1.5 and 10 in the range 1.5<z<2.0.
Description:
The SDF (J2000 position: 13:24:39+27:29:26) was first imaged by
Kashikawa et al. (2004PASJ...56.1011K 2004PASJ...56.1011K) with the Suprime-Cam camera on
the Subaru 8.2-m telescope on Mauna Kea, Hawaii.
We reimaged the field on four separate epochs (ut dates are used
throughout this paper): 2005 March 5 and 6 (epoch 2, analysed by
P07b); 2007 February 12-15 (epoch 3); 2007 May 15 and 16 (epoch 4)
and 2008 June 1-4 (epoch 5).
