Some Uses of Neutrino Telescopes

We imagine that large neutrino telescopes will be built and that distant neutrino sources of high energies and fluxes exist. Some possible, if difficult, uses to which they might be put are described; including (i) detecting neutrino mass-mixing possibly upto δm of 10eV ; (ii) measuring neutrino cross-sections at PeV energies; (iii) detecting relic neutrinos; (iv) doing cosmology with neutrinos...

The feasibility of large refracting telescopes for solar coronal research

Measuring magnetic fields in the solar corona requires a large aperture telescope with exceptionally low levels of scattered light. For internally-occulted coronagraphs the main source is scattering from dust or microroughness on the primary lens or mirror. We show refracting primaries offer significantly lower levels for both sources. To observe magnetic fields in the solar corona with scienti...

The Scaling Relationship Between Telescope Cost and Aperture Size for Very Large Telescopes

Cost data for ground-based telescopes of the last century are analyzed for trends in the relationship between aperture size and cost. We find that for apertures built prior to 1980, costs scaled as aperture size to the 2.8 power, which is consistent with the previous finding of Meinel (1978). After 1980, ‘traditional’ monolithic mirror telescope costs have scaled as aperture to the 2.5 power. T...

Operational Concepts of Large Telescopes *

The singular way of scheduling at major observatories has favored certain types of astronomy. This has led to the discrimination of certain types of observations which could not be accommodated. It is the goal of future operations to open possibilities for some additional types of observational astronomy. Together with improved observatory operations the new observing modes can provide signific...

Massive galaxy clusters as gravitational telescopes for distant supernovae

We investigate the potential of using massive clusters as gravitational telescopes for searches and studies of supernovae of Type Ia and Type II in optical and near-infrared bands at central wavelengths in the interval 0.8-1.25 μm. Using high-redshift supernova rates derived from the measured star formation rate, we find the most interesting effects for the detection of core-collapse SNe in sea...
