The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned

Posted by dbos October 17, 2023Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Steph Sallum, Shrishmoy Ray, Jens Kammerer, Anand Sivaramakrishnan, Rachel Cooper | Summary: We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NIRISS). Thanks to self-calibrating observables, AMI accesses inner working angles […]

ALMA gas-dynamical mass measurement of the supermassive black hole in the red nugget relic galaxy PGC 11179

Posted by dbos October 17, 2023October 30, 2023Peking

Kavli Affiliate: Luis Ho | First 5 Authors: Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh, Kyle M. Kabasares, Benjamin D. Boizelle | Summary: We present 0$.!!^{primeprime}22$-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO(2$-$1) emission from the circumnuclear gas disk in the red nugget relic galaxy PGC 11179. The disk shows regular rotation, with […]

Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?

Posted by dbos October 17, 2023October 30, 2023Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Daniel Harsono, Feng Long, Paola Pinilla, Alessia A. Rota, Carlo F. Manara | Summary: While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This paper presents dual-wavelength Atacama Large […]

Low energy electrodynamics and a hidden Fermi liquid in the heavy-fermion CeCoIn$_5$

Posted by dbos October 17, 2023October 30, 2023Cornell

Kavli Affiliate: Kyle Shen | First 5 Authors: L. Y. Shi, Zhenisbek Tagay, Jiahao Liang, Khoan Duong, Yi Wu | Summary: We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn$_5$. The complex optical conductivity is analyzed through a Drude model and extended Drude model analysis. Below the $approx$ 40 K Kondo […]

Global solutions of 2D non-resistive MHD system with constant background magnetic vorticity

Posted by dbos October 17, 2023UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yuanyuan Qiao, Yi Zhou, , , | Summary: This paper investigates the stabilization effect of a background magnetic vorticity on electrically conducting fluids. By exploring the dissipation nature of the linearized equations, we prove the global existence of smooth solutions to the two-dimensional incompressible viscous and non-resistive […]

Global solutions of 2D non-resistive MHD system under a magnetic vortex background

Posted by dbos October 17, 2023October 30, 2023UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yuanyuan Qiao, Yi Zhou, , , | Summary: We investigate the global well-posedness of two-dimensional incompressible viscous and non-resistive MHD system near a non-constant equilibrium. Assuming that the initial data has certain symmetries, we can establish time-weighted lower-order energy estimates and uniform higher-order energy estimates by exploring […]

Results and Limits of Time Division Multiplexing for the BICEP Array High Frequency Receivers

Posted by October 16, 2023Stanford

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 […]
