Detection Level Enhancement of Gravitational Microlensing Events from the...

In Astronomy, intensity of the source light is expressed in magnitude. Conventionally, magnitude is defined by logarithmic function of the received flux. This relationship is known as Pogson formulae....

How to coadd images? II. A coaddition image that is optimal for any purpose...

Image coaddition is one of the most basic operations that astronomers perform. In Paper~I, we presented the optimal ways to coadd images in order to detect faint sources and to perfrom flux...

Dynamic spectral mapping of interstellar plasma lenses [Replacement]

Compact radio sources sometimes exhibit intervals of large, rapid changes in their flux-density, due to lensing by interstellar plasma crossing the line-of-sight. A novel survey program has made it...

Performance of the Birmingham Solar-Oscillations Network (BiSON) [Replacement]

The Birmingham Solar-Oscillations Network (BiSON) has been operating with a full complement of six stations since 1992. Over 20 years later, we look back on the network history. The meta-data from the...
