Weak evidence for sardine collapse

Weak-interaction processes during stellar collapse

Massive stars end their lifes as type II supernovae, triggered by a collapse of their central iron core with a mass of more than 1M . The general picture of a core-collapse supernova is probably well understood and has been confirmed by various observations from supernova 1987A. Nevertheless, the most sophisticated supernova simulations [1, 2, 3] currently fail to explode indicating that improv...

Observational Evidence for Weak Lensing

A single very deep 10 0 eld has been imaged to r 26. There are 2682 galaxies with 23 r 26 with a size signiicantly larger than the seeing disk in the eld. After correcting for telescope aberrations, possible guiding errors, and signal degradation due to seeing, I nd a polarization signal of amplitude jpj = 2:7%, with an uncertainty of 1.2% (95% conndence limit). For the 1773 galaxies with 23 r ...

Evidence for weak oceanic transform faults

[1] We present the results of a series of 3-D boundary element calculations to investigate the effects of oceanic transform faults on stress state and fault development at adjacent mid-ocean ridge spreading centers. We find that the time-averaged strength of transform faults is low, and that on time scales longer than a typical earthquake cycle transform faults behave as zones of significant we...

Strong evidence for protein epistasis, weak evidence against it.

Evidence for Weak Lensing of Supernovae

Due to the deflection of light by density fluctuations along the line of sight, weak lensing is an unavoidable systematic uncertainty in the use of type Ia supernovae (SNe Ia) as cosmological distance indicators. We derive the expected weak lensing signatures of SNe Ia by convolving the intrinsic distribution in SN Ia peak luminosity with magnification distributions of point sources. We find th...
