Accuracy Analysis for Shack–Hartmann Wave Front Sensing with Extended Sources
The Astrophysical JournalCorrelating the Shack–Hartmann wave front sensor (SH-WFS) with extended targets is widely used in solar adaptive optics systems. This paper aims to introduce a theoretical analysis that evaluates the accuracy of the SH-WFS on extended sources, with a ...

The Astrophysical Journal Supplement SeriesAccurately measuring the Hubble parameter is vital for understanding the expansion history and properties of the Universe. In this paper, we propose a new method that supplements the covariance between redshift pairs to improve the reconstruction of the ...

The ALMA-QUARKS Survey: Detection of Two Extremely Dense Substructures in a Massive Prestellar Core
The Astrophysical Journal LettersOnly a handful of massive starless core candidates have been discovered so far, but none of them have been fully confirmed. Within the MM1 clump in the filamentary infrared dark cloud G34.43+0.24 that was covered by the Atacama Large Millimeter ...

Detection of Tidally Excited Oscillations in Kepler Heartbeat Stars
The Astrophysical JournalHeartbeat stars (HBSs) with tidally excited oscillations (TEOs) are ideal laboratories for studying the effect of equilibrium and dynamical tides. However, studies of TEOs in Kepler HBSs are rare due to the need for better modeling of the equilibrium ...

Excitation of Quasiperiodic Fast-propagating Waves in the Early Stage of the Solar Eruption
The Astrophysical JournalWe propose a mechanism for the excitation of large-scale quasiperiodic fast-propagating magnetoacoustic (QFP) waves observed on both sides of the coronal mass ejection. Through a series of numerical experiments, we successfully simulated the quasi-static

Large-scale Anisotropy of Galactic Cosmic Rays as a Probe of Local Cosmic-Ray Propagation
The Astrophysical JournalRecent studies have shown that the anisotropy is of great value to decipher cosmic rays’ origin and propagation. We have built a unified scenario to describe the observations of the energy spectra and the large-scale anisotropy and called attention to ...
