Submillimeter and millimeter wavelengths can reveal a vast range of objects and
phenomena that are either too cold, too distant, or too hot and energetic to be measured at …

Plain language summary Galaxies come in a wide variety of shapes, sizes, and colours,
despite all of them having originated from similar initial conditions in the early Universe …

Context. CarbON CII line in post-rEionisation and ReionisaTiOn epoch (CONCERTO)
instrument is a low-resolution mapping spectrometer based on lumped element kinetic …

We present a “mix-and-match” process to create large structures with submicrometer
features by combining UV contact lithography and 100 kV electron-beam lithography in a …

This thesis treats the topic of CMB Spectral Distortions (SDs), which represent any deviation
from a pure black body shape of the CMB energy spectrum. As such, they can be used to …

Context. Integrated superconducting spectrometers (ISSs) for wide-band submillimeter
(submm) astronomy use quasi-optical systems for coupling radiation from the telescope to …

Many superconducting on-chip filter-banks suffer from poor coupling to the detectors behind
each filter. This is a problem intrinsic to the commonly used half-wavelength filter, which has …

Integrated superconducting spectrometers (ISSs) for wideband sub-mm astronomy utilise
quasi-optical systems for coupling radiation from the telescope to the instrument …

In order to meet the needs of the femi-ultra-high spectral resolution test, an optical system of
the femi-ultra-high spectral resolution spectrometer in the spectral range of 190–800 nm is …

Traditional technologies for far-infrared (FIR) spectroscopy generally involve bulky
dispersive optics. Integrated filter bank spectrometers promise more compact designs, but …
