Supernovae and Cosmology with Future European Facilities
I. M. Hook
Prospects for future supernova surveys are discussed, focusing on the ESA Euclid mission and the European Extremely Large Telescope(E-ELT), both expected to be in operation around…
PTF11kx: A Type-Ia Supernova with a Symbiotic Nova Progenitor
B. Dilday, D. A. Howell, S. B. Cenko +32
There is a consensus that Type-Ia supernovae (SNe Ia) arise from the thermonuclear explosion of white dwarf stars that accrete matter from a binary companion. However, direct obser…
Evolution in the Volumetric Type Ia Supernova Rate from the Supernova Legacy Survey
K. Perrett, M. Sullivan, A. Conley +23
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate (SNR_Ia) as a function of redshift for the first four years of data from the Canada-France-Hawaii Telescop…
Testing the distance duality relation with present and future data
Vincenzo F. Cardone, Susanna Spiro, Isobel Hook +1
The assumptions that "light propagates along null geodesics of the spacetime metric" and "the number of photons is conserved along the light path" lead to the distance duality rela…
An Efficient Approach to Obtaining Large Numbers of Distant Supernova Host Galaxy Redshifts
C. Lidman, V. Ruhlmann-Kleider, M. Sullivan +20
We use the wide-field capabilities of the 2dF fibre positioner and the AAOmega spectrograph on the Anglo-Australian Telescope (AAT) to obtain redshifts of galaxies that hosted supe…
Hubble Space Telescope studies of low-redshift Type Ia supernovae: Evolution with redshift and ultraviolet spectral trends
K. Maguire, M. Sullivan, R. S. Ellis +26
We present an analysis of the maximum light, near ultraviolet (NUV; 2900-5500 A) spectra of 32 low redshift (0.001<z<0.08) Type Ia supernovae (SNe Ia), obtained with the Hubble Spa…
