Planck-LFI: Design and Performance of the 4 Kelvin Reference Load Unit
Luca Valenziano, Francesco Cuttaia, Adriano De Rosa +35
The LFI radiometers use a pseudo-correlation design where the signal from the sky is continuously compared with a stable reference signal, provided by a cryogenic reference load sy…
Gravitomagnetic Clock Effect: Using GALILEO to explore General Relativity
Jan Scheumann, Dennis Philipp, Sven Herrmann +5
All experiments to date are in remarkable agreement with the predictions of Einstein's theory of gravity, General Relativity. Besides the classical tests, involving light deflectio…
Searching for large dark matter clumps using the Galileo Satnav clock variations
Bruno Bertrand, Pascale Defraigne, Aurélien Hees +8
This study presents bounds on transient variations of fundamental constants, with typical timescales ranging from minutes to months, using clocks in space. The underlying phenomeno…
Submarine Navigation using Neutrinos
Javier Fidalgo Prieto, Stefano Melis, Ana Cezon +9
Neutrinos are among the most abundant particles in the universe, nearly massless, travel at speeds near the speed of light and are electrically neutral. Neutrinos can be generated…
First search for ultralight dark matter with a space-based gravitational-wave antenna: LISA Pathfinder
Andrew L. Miller, Luis Mendes
We present here results from the first-ever search for dark photon dark matter that could have coupled to baryons in LISA Pathfinder, the technology demonstrator for a space-based…
Autonomous RPCs for a Cosmic Ray ground array
Pedro Assis, Alberto Blanco, Nuno Carolino +15
We report on the behaviour of Resistive Plate Chambers (RPC) developed for muon detection in ultra-high energy cosmic ray (UHECR) experiments. The RPCs were developed for the MARTA…
