Discovery of a supernova explosion at half the age of the Universe

The ultimate fate of the Universe, infinite expansion or a big crunch, can be determined by using the redshifts and distances of very distant supernovae to monitor changes in the expansion rate. We can now find¹ ...

Scheduled Discoveries of 7+ High-Redshift Supernovae:First Cosmology Results and Bounds on q ₀

Our search for high-redshift Type Ia supernovae discovered, in its first years, a sample of seven supernovae. Using a “batch” search strategy, almost all were discovered before maximum light and were observed ...

Observation of Cosmological Time Dilation Using Type Ia Supernovae as Clocks

This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0.3 — 0.5, before or at maximum l...

The Type Ia Supernova Rate at z ~ 0.4

We present the first measurement of the rate of Type Ia supernovae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as described in more detail at this ...

Projected performance of a large superfluid helium solar neutrino detector

Based upon experiments carried out using radioactive sources to investigate the particle detection properties of superfluid helium we project a configuration for and the response of a full scale detector for s...

The evaporation signal from α particles stopped in superfluid helium

Alpha particles stopped in a 3 liter volume of liquid helium at 30 mK are observed by the calorimetric detection of helium atoms evaporated from the free surface of the liquid. Quantum evaporation of the heliu...

Reciprocal effects of prolactin and thyroxine on the growth rate of rat pups from weaning to puberty

Prolactin and thyroxine were added to the daily diet of rat pups from weaning to puberty (days 20–40). While prolactin significantly retarted the pups’ growth, thyroxine stimulated growth and even compensated ...
