A Decade of Solar High-Fidelity Spectroscopy and Precise Radial Velocities from HARPS-N
X. Dumusque, K. Al Moulla, M. Cretignier +53
We recently released 10 years of HARPS-N solar telescope and the goal of this manuscript is to present the different optimisations made to the data reduction, to describe data cura…
Machine Learning for Improved Current Density Reconstruction from 2D Vector Magnetic Images
Niko R. Reed, Danyal Bhutto, Matthew J. Turner +8
The reconstruction of electrical current densities from magnetic field measurements is an important technique with applications in materials science, circuit design, quality contro…
Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network
T. W. Milbourne, D. F. Phillips, N. Langellier +21
State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
Identifying Exoplanets with Deep Learning. IV. Removing Stellar Activity Signals from Radial Velocity Measurements Using Neural Networks
Zoe L. de Beurs, Andrew Vanderburg, Christopher J. Shallue +24
Exoplanet detection with precise radial velocity (RV) observations is currently limited by spurious RV signals introduced by stellar activity. We show that machine learning techniq…
Detection Limits of Low-mass, Long-period Exoplanets Using Gaussian Processes Applied to HARPS-N Solar RVs
N. Langellier, T. W. Milbourne, D. F. Phillips +29
Radial velocity (RV) searches for Earth-mass exoplanets in the habitable zone around Sun-like stars are limited by the effects of stellar variability on the host star. In particula…
Magnetic Field Fingerprinting of Integrated Circuit Activity with a Quantum Diamond Microscope
Matthew J. Turner, Nicholas Langellier, Rachel Bainbridge +9
Current density distributions in active integrated circuits (ICs) result in patterns of magnetic fields that contain structural and functional information about the IC. Magnetic fi…
Principles and Techniques of the Quantum Diamond Microscope
Edlyn V. Levine, Matthew J. Turner, Pauli Kehayias +6
We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the Quantum Diamond Microscope (QDM). The QDM employs a dense layer of fl…
HARPS-N Solar Radial-Velocity Variations Are Dominated By Large, Bright Magnetic Regions
T. W. Milbourne, R. D. Haywood, D. F. Phillips +37
State of the art radial-velocity (RV) exoplanet searches are currently limited by RV signals arising from stellar magnetic activity. We analyze solar observations acquired over a 3…
Probing Dark Matter Using Precision Measurements of Stellar Accelerations
Aakash Ravi, Nicholas Langellier, David F. Phillips +3
Dark matter comprises the bulk of the matter in the universe but its particle nature and cosmological origin remain mysterious. Knowledge of the dark matter density distribution in…
Gravitational wave detection with optical lattice atomic clocks
Shimon Kolkowitz, Igor Pikovski, Nicholas Langellier +3
We propose a space-based gravitational wave detector consisting of two spatially separated, drag-free satellites sharing ultra-stable optical laser light over a single baseline. Ea…
