A Lunar Farside Low Radio Frequency Array for Dark Ages 21-cm Cosmology

Kavli Affiliate: Albert Stebbins | First 5 Authors: Jack Burns, Gregg Hallinan, Tzu-Ching Chang, Marin Anderson, Judd Bowman | Summary: An array of low-frequency dipole antennas on the lunar farside surface will probe a unique, unexplored epoch in the early Universe called the Dark Ages. It begins at Recombination when neutral hydrogen atoms formed, first […]

Holographic surface measurement system for the Fred Young Submillimeter Telescope

Kavli Affiliate: Richard Hills | Summary:We describe a system being developed for measuring the shapes of the mirrors of the Fred Young Submillimeter Telescope (FYST), now under construction for the CCAT Observatory. "Holographic" antenna-measuring techniques are an efficient and accurate way of measuring the surfaces of large millimeter-wave telescopes and they have the advantage of […]

Accurate Measurement of the Gap of Graphene/hBN Moiré Superlattice through Photocurrent Spectroscopy

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Tianyi Han, Jixiang Yang, Qihang Zhang, Lei Wang, Kenji Watanabe | Summary: Monolayer graphene aligned with hexagonal boron nitride (hBN) develops a gap at the charge neutrality point (CNP). This gap has previously been extensively studied by electrical transport through thermal activation measurements. Here, we report […]
