Posted by klaurent Peking

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

Posted by klaurent MIT

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

Posted by klaurent Peking

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

Posted by dbos Harvard

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 […]

Constraining galaxy overdensities around three z~6.5 quasars with ALMA and MUSE

Posted by klaurent Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Romain A. Meyer, Roberto Decarli, Fabian Walter, Qiong Li, Ran Wang | Summary: We quantify galaxy overdensities around three high-redshift quasars with known [CII] 158um companions: PJ231-20 (z=6.59), PJ308-21 (z=6.24) and J0305-3150 (z=6.61). Recent SCUBA2 imaging revealed the presence of 17 submillimeter galaxies (SMG) with sky separations […]

Stability of Oxygenated Groups on Pristine and Defective Diamond Surfaces

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Eliezer Oliveira, Chenxi Li, Xiang Zhang, Anand Puthirath, Mahesh R. Neupane | Summary: The surface functionalization of diamond has been extensively studied through a variety of techniques, such as oxidation. Several oxygen groups have been correspondingly detected on the oxidized diamond, such as COC (ester), CO (ketonic), […]

Optimizing Gravitational-Wave Detector Design for Squeezed Light

Posted by klaurent Caltech

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Jonathan W. Richardson, Swadha Pandey, Edita Bytyqi, Tega Edo, Rana X. Adhikari | Summary: Squeezed light is critical in gravitational-wave detection for reaching sensitivities below the standard quantum limit. Achieving the quantum noise targets of third-generation detectors will require 10 dB of squeezing as well as […]
