Foreground Removal in Ground-Based CMB Observations Using a Transformer Model
Ye-Peng Yan, Si-Yu Li, Yang Liu +2
We present a novel method for Cosmic Microwave Background (CMB) foreground removal based on deep learning techniques. This method employs a Transformer model, referred to as \textt…
CMBFSCNN: Cosmic Microwave Background Polarization Foreground Subtraction with Convolutional Neural Network
Ye-Peng Yan, Si-Yu Li, Guo-Jian Wang +2
In our previous study, we introduced a machine-learning technique, namely CMBFSCNN, for the removal of foreground contamination in cosmic microwave background (CMB) polarization da…
Lensing reconstruction from the cosmic microwave background polarization with machine learning
Ye-Peng Yan, Guo-Jian Wang, Si-Yu Li +2
The lensing effect of the cosmic microwave background (CMB) is a powerful tool for our study of the distribution of matter in the universe. Currently, the quadratic estimator (EQ)…
Delensing of Cosmic Microwave Background Polarization with machine learning
Ye-Peng Yan, Guo-Jian Wang, Si-Yu Li +1
Primordial B-mode detection is one of the main goals of next-generation cosmic microwave background (CMB) experiments. Primordial B-modes are a unique signature of primordial gravi…
Recovering Cosmic Microwave Background Polarization Signals with Machine Learning
Ye-Peng Yan, Guo-Jian Wang, Si-Yu Li +1
Primordial B-mode detection is one of the main goals of current and future cosmic microwave background (CMB) experiments. However, the weak B-mode signal is overshadowed by several…
Recovering the CMB Signal with Machine Learning
Guo-Jian Wang, Hong-Liang Shi, Ye-Peng Yan +4
The cosmic microwave background (CMB), carrying the inhomogeneous information of the very early universe, is of great significance for understanding the origin and evolution of our…
Element abundance analysis of the metal-rich stellar halo and high-velocitythick disk in the galaxy
Haifan Zhu, Cuihua Du, Yepeng Yan +3
Based on the second Gaia data release (DR2) and APOGEE (DR16) spectroscopic surveys, wedefined two kinds of star sample: high-velocity thick disk (HVTD) with and metal-…
Existence of the Metal-Rich Stellar Halo and High-velocity Thick Disk in the Galaxy
Yepeng Yan, Cuihua Du, Hefan Li +3
Based on the second Gaia data release (DR2), combined with the LAMOST and APOGEE spectroscopic surveys, we study the kinematics and metallicity distribution of the high-velocity st…
New nearby hypervelocity stars and their spatial distribution from Gaia DR2
Cuihua Du, Hefan Li, Yepeng Yan +5
Base on about 4,500 large tangential velocity () with high-precision proper motions and parallaxes in Gaia DR2 5D information derived from p…
Chemical and Kinematic Properties of the Galactic Disk from the LAMOST and Gaia Sample Stars
Yepeng Yan, Cuihua Du, Shuai Liu +5
We determined the chemical and kinematic properties of the Galactic thin and thick disk using a sample of 307,246 A/F/G/K-type giant stars from the LAMOST spectroscopic survey and…
