X-ray Intra-day Variability of the TeV Blazar Mrk 421 with Suzaku
Zhongli Zhang, Alok C. Gupta, Haritma Gaur +5
We present X-ray flux and spectral analyses of the three pointed Suzaku observations of the TeV high synchrotron peak blazar Mrk 421 taken throughout its complete operational durat…
Contribution of Radio Halos to the Foreground for SKA EoR Experiments
Weitian Li, Haiguang Xu, Zhixian Ma +11
The overwhelming foreground contamination is one of the primary impediments to probing the Epoch of Reionization (EoR) through measuring the redshifted 21 cm signal. Among various…
Separating the EoR Signal with a Convolutional Denoising Autoencoder: A Deep-learning-based Method
Weitian Li, Haiguang Xu, Zhixian Ma +7
When applying the foreground removal methods to uncover the faint cosmological signal from the epoch of reionization (EoR), the foreground spectra are assumed to be smooth. However…
Revealing A Head-on Major Merger in the Nearby NGC 6338 Group with Chandra and VLA observations
Yu Wang, Fuyao Lui, Zhiqiang Shen +3
By analyzing the Chandra archival data of the nearby NGC 6338 galaxy group, we identify two X-ray bright clumps (N-clump and S-clump) within the central 100 kpc, and detect an arc-…
