Accuracy Analysis for Shack–Hartmann Wave Front Sensing with Extended Sources

open access: yesThe Astrophysical Journal
Correlating 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 ...

A Nonparametric Reconstruction of the Hubble Parameter H(z) Based on Radial Basis Function Neural Networks

open access: yesThe Astrophysical Journal Supplement Series
Accurately 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 ...

Rapid Generation of Kilonova Light Curves Using Conditional Variational Autoencoder

open access: yesThe Astrophysical Journal
The discovery of the optical counterpart, along with the gravitational waves (GWs) from GW170817, of the first binary neutron star merger has opened up a new era for multimessenger astrophysics.

The ALMA-QUARKS Survey: Detection of Two Extremely Dense Substructures in a Massive Prestellar Core

open access: yesThe Astrophysical Journal Letters
Only 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

open access: yesThe Astrophysical Journal
Heartbeat 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

open access: yesThe Astrophysical Journal
We 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
