Astronomy and the new SI
Prasenjit Saha
In 2019 the International System of units (SI) conceptually re-invented itself. This was necessary because quantum-electronic devices had become so precise that the old SI could no…
Lessons from a blind study of simulated lenses: image reconstructions do not always reproduce true convergence
Philipp Denzel, Sampath Mukherjee, Jonathan P. Coles +1
In the coming years, strong gravitational lens discoveries are expected to increase in frequency by two orders of magnitude. Lens-modelling techniques are being developed to prepar…
Microlensing masses via photon bunching
Prasenjit Saha
In microlensing of a Galactic star by a brown dwarf or other compact object, the amplified image really consists of two unresolved images with slightly different light-travel times…
Primordial Gravitational Waves in the Cosmic Bubble Chamber
Raymond Angélil, Prasenjit Saha, Jürg Diemand
We explore the effect of relic gravitational waves on the primordial phase change from the quark-gluon plasma into the low density hadron gas that occurred approximately s…
