A Non-Negativity Iterative Approach to Image Deconvolution for SKA
Le Zhang, Shiyu Li
We introduce a novel algorithm for image deconvolution applicable to interferometric radio observations, based on the assumption of non-negative source fluxes. The method enables r…

The diverse physical origins of stars in the dynamically hot bulge: CALIFA vs. IllustrisTNG
Le Zhang, Ling Zhu, Annalisa Pillepich +3
We compare the internal stellar structures of central galaxies in the TNG50 and TNG100 simulations and field galaxies in the CALIFA survey. The luminosity fractions of the dynamica…

Reconstructing the Thermal Sunyaev Zeldovich Power Spectrum from Planck using the ABS Method
Zhaoxuan Zhang, Le Zhang, Pengjie Zhang
This study employs a novel approach for reconstructing the thermal Sunyaev-Zeldovich (tSZ) effect power spectrum from Planck data using the Analytical Blind Separation (ABS) method…
