The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Lily L. Zhao, Debra A. Fischer, Eric B. Ford, Alex Wise, Michaël Cretignier | Summary: Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precision radial velocity (EPRV) exoplanet detection. Several methods […]

Accurate effective fluid approximation for ultralight axions

Kavli Affiliate: Wayne Hu | First 5 Authors: Samuel Passaglia, Wayne Hu, , , | Summary: Ultralight axions are theoretically interesting and phenomenologically rich dark sector candidates, but they are difficult to track across cosmological timescales because of their fast oscillations. We resolve this problem by developing a novel method to evolve them efficiently and […]

ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions — VIII. A search for hot cores by using C$_2$H$_5$CN, CH$_3$OCHO and CH$_3$OH lines

Kavli Affiliate: Ke Wang | First 5 Authors: Sheng-Li Qin, Tie Liu, Xunchuan Liu, Paul F. Goldsmith, Di Li | Summary: Hot cores characterized by rich lines of complex organic molecules are considered as ideal sites for investigating the physical and chemical environments of massive star formation. We present a search for hot cores by […]

A massive AGB donor in Scutum X-1: Identification of the first Mira variable in an X-ray binary

Kavli Affiliate: Robert Simcoe | First 5 Authors: Kishalay De, Deepto Chakrabarty, Roberto Soria, Michael C. B. Ashley, Charlie Conroy | Summary: The symbiotic X-ray binary Sct X-1 was suggested as the first known neutron star accreting from a red supergiant companion. Although known for nearly 50 years, detailed characterization of the donor remains lacking, […]

Mid-infrared Variability of Low-redshift Active Galactic Nuclei : Constraints on a Hot Dust Component with a Variable Covering Factor

Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, , | Summary: We utilize mid-infrared multi-epoch data from Wide-field Infrared Survey Explorer (WISE) over a $sim10$-year period in W1 (3.4$mu$m) and W2 (4.6$mu$m) bands to investigate the structure of dusty torus in low-redshift ($0.15<zle 0.4$) active galactic nuclei […]

Improved tracking of particles with highly correlated motion

Kavli Affiliate: David A. Weitz | First 5 Authors: Ella M. King, Zizhao Wang, David A. Weitz, Frans Spaepen, Michael P. Brenner | Summary: Despite significant advances in particle imaging technologies over the past two decades, few advances have been made in particle tracking, i.e. linking individual particle positions across time series data. The state-of-the-art […]
