Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: , , , , | Summary: Time-Division Multiplexing is the readout architecture of choice for many ground and space experiments, as it is a very mature technology with proven outstanding low-frequency noise stability, which represents a central challenge in multiplexing. Once fully populated, each of the two […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Sihan Yuan, Risa H. Wechsler, Yunchong Wang, Mithi A. C. de los Reyes, Justin Myles | Summary: Emission line galaxies (ELGs) are now the preeminent tracers of large-scale structure at z>0.8 due to their high density and strong emission lines, which enable accurate redshift measurements. However, […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) is a $2-5~mu$m, high-contrast integral field spectrograph (IFS) currently being built for Keck Observatory. With both low ($Rlesssim250$) and medium ($Rsim3500-7000$) spectral resolution IFS modes, SCALES will detect and characterize […]

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: The classical field approximation is widely used to better understand the predictions of ultra-light dark matter. Here, we use the truncated Wigner approximation method to test the classical field approximation of ultra-light dark matter. This method approximates […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: The Gemini Planet Imager (GPI) is a high contrast imaging instrument that aims to detect and characterize extrasolar planets. GPI is being upgraded to GPI 2.0, with several subsystems receiving a re-design to improve the instrument’s contrast. To enable observations on […]

Kavli Affiliate: Robert Cameron | First 5 Authors: Veronika Witzke, Alexander I. Shapiro, Nadiia M. Kostogryz, Lucien Mauviard, Tanayveer S. Bhatia | Summary: Three-dimensional (3D) radiative magnetohydrodynamics (MHD) simulations are the only way to model stellar atmospheres without any ad hoc parameterisations. Several 3D radiative MHD codes have achieved good quantitative agreement with observables for […]

Kavli Affiliate: Tom Abel | First 5 Authors: Sihan Yuan, Tom Abel, Risa H. Wechsler, , | Summary: We present the methodology for deriving accurate and reliable cosmological constraints from non-linear scales (<50Mpc/h) with k-th nearest neighbor (kNN) statistics. We detail our methods for choosing robust minimum scale cuts and validating galaxy-halo connection models. Using […]

Kavli Affiliate: Robert L. Byer | First 5 Authors: Payton Broaddus, Thilo Egenolf, Dylan S. Black, Melanie Murillo, Clarisse Woodahl | Summary: We demonstrate a silicon-based electron accelerator that uses laser optical near fields to both accelerate and confine electrons over extended distances. Two dielectric laser accelerators (DLA) designs were tested, each consisting of two […]
