A 21-cm power spectrum at 48 MHz, using the Owens Valley Long Wavelength Array

Kavli Affiliate: George Efstathiou | First 5 Authors: Hugh Garsden, Lincoln Greenhill, Gianni Bernardi, Anastasia Fialkov, Daniel C. Price | Summary: The Large-aperture Experiment to detect the Dark Age (LEDA) was designed to measure the 21-cm signal from neutral hydrogen at Cosmic Dawn, $z approx $15-30. Using observations made with the $approx $ 200 m […]

Scanning SQUID microscopy in a cryogen-free dilution refrigerator

Kavli Affiliate: Katja C. Nowack | First 5 Authors: D. Low, G. M. Ferguson, Alexander Jarjour, Brian T. Schaefer, Maja D. Bachmann | Summary: We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least 30 mK. The microscope is […]

Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)

Kavli Affiliate: Subo Dong | First 5 Authors: S. J. Brennan, M. Fraser, J. Johansson, A. Pastorello, R. Kotak | Summary: We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current literature by adding higher cadence as well as extended coverage […]

Two-dimensional charge order stabilized in clean polytype heterostructures

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Suk Hyun Sung, Noah Schnitzer, Steve Novakov, Ismail El Baggari, Xiangpeng Luo | Summary: Compelling evidence suggests distinct correlated electron behavior may exist only in clean 2D materials such as 1T-TaS2. Unfortunately, experiment and theory suggest that extrinsic disorder in free standing 2D layers disrupts correlation-driven […]
