iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova.
We report the discovery of a multiply imaged, gravitationally lensed type Ia supernova, iPTF16geu (SN 2016geu), at redshift z = 0.409. This phenomenon was identified because the light from the stellar explosion was magnified more than 50 times by the curvature of space around matter in an intervening galaxy. We used high-spatial-resolution observations to resolve four images of the lensed super...
متن کاملCosmic Supernova Rate History and Type Ia Supernova Progenitors
We adopt a single-degenerate (SD) scenario, which assumes that a C+O white dwarf accretes H-rich meterials from the binary companion star and grows its mass to the Chandrasekhar mass to explode as a Type Ia supernova (SN Ia). There are two progenitor systems: One is a red-giant (RG) companion with the initial mass of MRG,0 ∼ 0.9 − 1.5M⊙ and an orbital period of tens to hundreds days 1 2 . The o...
متن کاملSupernovae, the Lensed Cosmic Microwave Background, and Dark Energy
Supernova distance and primary cosmic microwave background (CMB) anisotropy measurements provide us with powerful probes of the dark energy evolution in a flat universe, but they degrade substantially once curvature is marginalized. We show that lensed CMB polarization power spectrum measurements, accessible to next generation ground-based surveys such as SPTpol or QUIET, can remove the curvatu...
متن کاملThe 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...
متن کاملCosmic rays, stellar evolution, and supernova physics
Most cosmic rays are thought to be accelerated by the shocks of supernova explosions of very massive stars. Here we review one quantitative proposal, which predicted the spectral slopes, bend and cutoff about the cosmic ray spectrum across the spectral bend or “knee” near 3 10 eV in 1993. Many of the specific predictions have now been verified, and so it may be appropiate to investigate the con...
