Transformer-Based Source Detection and Morphological Classification in LOFAR Deep-Field Continuum Images
Guangwen Chen, Kristian Z. Adami, John Abela +7
Radio source detection and morphological classification are fundamental for exploiting the scientific potential of modern radio continuum surveys. However, the rapidly increasing d…
A Spatially Resolved HI Survey of Seyfert Galaxies: the Role of AGN Feedback in Shaping Atomic Gas Reservoirs
Ruitian Li, Xin Wang, Daizhong Liu +19
Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir -- the neutral hydrogen (HI) phase -- remains poorly…
Transition from Outside-in to Inside-Out at : Evidence from Radial Profiles of Specific Star Formation Rate based on JWST/HST
Jie Song, Enci Wang, Cheng Jia +7
By combining high-resolution observations from JWST and HST, we have measured the stellar masses, star formation rates (SFRs), and multi-wavelength morphologies of galaxies in the…
HiFAST: An HI Data Calibration and Imaging Pipeline for FAST III. Standing Wave Removal
Chen Xu, Jie Wang, Yingjie Jing +13
The standing waves existed in radio telescope data are primarily due to reflections among the instruments, which significantly impact the spectrum quality of the Five-hundred-meter…
