Predict in Chunks, Revise in Spans: History-conditioned Action Regeneration for Robotic Manipulation
Chenyang Wang, Yuntian Wang, Jiaying Tang +3
Action chunking improves temporal coherence in visuomotor imitation learning by jointly predicting sequences of future actions. However, many existing policies regenerate entire ac…
The Evolution of Thermal and Non-thermal Emission Components in GRB 250920C
Jia-Ming Chen, Ke-Rui Zhu, Shan Chang +5
We present a temporal and time-resolved spectral analysis of GRB 250920C using \textit{Fermi}/GBM and \textit{Swift}/BAT data. The prompt emission consists of two distinct episodes…
Modeling Gamma-Ray Burst Spectra with Convolutional Neural Networks: Fast-Cooling Synchrotron Emission in a Decaying Magnetic Field
Jia-Ming Chen, Ke-Rui Zhu, Shan Chang +3
The radiation mechanism of gamma-ray burst (GRB) prompt emission remains uncertain. Although the fast-cooling synchrotron model in a decaying magnetic field can account for the cha…
A Decade to Map the Diffuse Universe: FRB-QSO Pairs with HST/COS Spectroscopy
Jessica Werk, Matthew McQuinn, J. Xavier Prochaska +16
Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints o…
Fast-Cooling Synchrotron in Decaying Magnetic Fields: Implications for the GRB Spectral Distribution
Jia-Ming Chen, Ke-Rui Zhu, Zhao-Yang Peng +5
The prompt-emission spectra of gamma-ray bursts (GRBs) are commonly described by the empirical Band function. The typical low-energy spectral index is , which poses a chal…
A Universal 1.5 GeV Gamma-Ray Line in Active Galactic Nuclei
Shi-Ju Kang, Yue Yin, Yong-Gang Zheng +1
We report the detection of a gamma-ray spectral line at approximately 1.5 GeV in three active galactic nuclei (AGN) using 17 years of Fermi-LAT observations. The sample includes bo…
Discovery of Repeating Transitions in 16 Changing-look Active Galactic Nuclei
Qian Dong, Zhi-Xiang Zhang, Wei-Min Gu +5
The repeating changing-look active galactic nuclei (RCL AGNs) exhibit multiple appearances and disappearances of broad emission lines (BELs), whose underlying mechanism remains a p…
Hunting for the candidates of Changing-Look Blazar using Mclust Clustering Analysis
Shi-Ju Kang, Shan-Shan Ren, Yong-Gang Zheng +1
The changing-look blazars (CLBs) are the blazars that their optical spectral lines at different epochs show a significant changes and present a clear transition between the standar…
Newly Discovered Changing-look Active Galactic Nuclei from SDSS and LAMOST Surveys
Qian Dong, Zhi-Xiang Zhang, Wei-Min Gu +2
Changing-look Active Galactic Nuclei (CL AGNs) exhibit drastic variations in broad emission lines (BELs), the mechanism of which remains unclear. Expanding the sample of CL AGNs is…
The Physical Properties of Changing-look Blazars
Shi-Ju Kang, Bing Lyu, Qingwen Wu +2
Changing-look active galactic nuclei (AGNs) are a special class of AGNs that change their spectral type from type 1 to type 2 or vice versa. In recent years, a number of changing-l…
