A singularity free classical theory of gravity

Saurya Das, Mitja Fridman, Sourav Sur

We present a classical theory of gravity, which is singularity free at short distances and reduces to General Relativity at large distances. We discuss its implications.

Correcting the extended-source calibration for the Herschel-SPIRE Fourier-Transform Spectrometer

Ivan Valtchanov, R. Hopwood, G. Bendo +20

We describe an update to the Herschel-SPIRE Fourier-Transform Spectrometer (FTS) calibration for extended sources, which incorporates a correction for the frequency-dependent far-f…
