Revealing observatory networks through object stories: Observatory audiences

open access: yesScience Museum Group Journal, 2023
Like the contributions to the other papers in this collection (‘Object itineraries’ and ‘Instrumental networks’), those in this final section explore instrumental networks and object itineraries in order to tell new histories of observatory sites and ...

The IceCube Neutrino Observatory: Instrumentation and Online Systems [PDF]

open access: yes, 2016
The IceCube Neutrino Observatory is a cubic-kilometer-scale high-energy neutrino detector built into the ice at the South Pole. Construction of IceCube, the largest neutrino detector built to date, was completed in 2011 and enabled the discovery of high ...

Identifying Clouds over the Pierre Auger Observatory using Infrared Satellite Data [PDF]

open access: yes, 2013
We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud identifications resulting from our method to those obtained by the Central Laser Facility of the Auger Observatory.

Observation of the Crab Nebula with the HAWC Gamma-Ray Observatory [PDF]

open access: yes, 2017
The Crab Nebula is the brightest TeV gamma-ray source in the sky and has been used for the past 25 years as a reference source in TeV astronomy, for calibration and verification of new TeV instruments. The High Altitude Water Cherenkov Observatory (HAWC),

Advancing All‐Day Passive Radiative Cooling Performance of 3D Anodized Aluminum Oxide Nanostructures on Aluminium

open access: yesAdvanced Optical Materials, EarlyView.
Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz

open access: yesAdvanced Photonics Research, EarlyView.
This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with
