A 20-Second Cadence View of Solar-Type Stars and Their Planets with TESS: Asteroseismology of Solar Analogs and a Re-characterization of pi Men c

Posted by klaurent MIT

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Daniel Huber, Timothy R. White, Travis S. Metcalfe, Ashley Chontos, Michael M. Fausnaugh | Summary: We present an analysis of the first 20-second cadence light curves obtained by the TESS space telescope during its extended mission. We find a precision improvement of 20-second data compared to […]

Search for dark-photon dark matter in the SuperMAG geomagnetic field dataset

Posted by klaurent Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia, | Summary: In our recent companion paper [arXiv:2106.00022], we pointed out a novel signature of ultralight kinetically mixed dark-photon dark matter. This signature is a quasi-monochromatic, time-oscillating terrestrial magnetic field that takes a particular […]

Field moment expansion method for interacting Bosonic systems

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Michael Kopp, Alvaro Zamora, Tom Abel, | Summary: We introduce a numerical method and python package, https://github.com/andillio/CHiMES, that simulates quantum systems initially well approximated by mean field theory using a second order extension of the classical field approach. We call this the field moment expansion […]

Neutron Star$-$Neutron Star and Neutron Star$-$Black Hole Mergers: Multiband Observations and Early Warnings

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Chang Liu, Lijing Shao, , , | Summary: The detections of gravitational waves (GWs) from binary neutron star (BNS) systems and neutron star–black hole (NSBH) systems provide new insights into dense matter properties in extreme conditions and associated high-energy astrophysical processes. However, currently information about NS equation […]

Low levels of sulphur dioxide contamination of Venusian phosphine spectra

Posted by klaurent MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Jane S. Greaves, Paul B. Rimmer, Anita M. S. Richards, Janusz J. Petkowski, William Bains | Summary: New analysis is presented of the 1.1 mm wavelength absorption lines in Venus’ atmosphere that suggested the presence of phosphine. We retrieve a sulphur dioxide observation from the JCMT archive […]

The air over there: exploring exoplanet atmospheres

Posted by klaurent Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: Laura Schaefer, Vivien Parmentier, , , | Summary: Atmospheric compositions for rocky exoplanets will depend strongly on the bulk planetary composition and the orbital position of the planet. Non-traditional gases may be present in the atmospheres of exceptionally hot planets. Atmospheres of more clement planets will depend […]

ECG-Based Heart Arrhythmia Diagnosis Through Attentional Convolutional Neural Networks

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Ziyu Liu, Xiang Zhang, , , | Summary: Electrocardiography (ECG) signal is a highly applied measurement for individual heart condition, and much effort have been endeavored towards automatic heart arrhythmia diagnosis based on machine learning. However, traditional machine learning models require large investment of time and effort […]

IQ Photonic Receiver for Coherent Imaging with a Scalable Aperture

Posted by klaurent Caltech

Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri, , | Summary: Silicon photonics (SiP) integrated coherent image sensors offer higher sensitivity and improved range-resolution-product compared to direct detection image sensors such as CCD and CMOS devices. Previous generation of SiP coherent imagers suffer from relative optical phase fluctuations between […]
