Searching in HI for Massive Low Surface Brightness Galaxies: II. Completing the UGC Sample
Karen O'Neil, Wim van Driel, Stephan Schneider
The paper reports new 21‑cm HI observations of 35 low surface brightness galaxies using the Green Bank Telescope, detecting 19 of them and adding accidental detections, to complete…
The Study of Quasi-Periodic Pulsations in Solar and Stellar Flares with SKA
Valery M. Nakariakov, Atul Mohan, Vishal Upendran +5
The paper outlines how the Square Kilometre Array (SKA) will enable detailed radio observations of quasi‑periodic pulsations in solar and stellar flares, leveraging high time‑resol…
Tidal Disruption Events with the SKA
T. An, A. J. Goodwin, J. C. A. Miller-Jones +3
The paper outlines how the Square Kilometre Array’s sensitivity, wide frequency coverage, and VLBI capabilities will enable large‑scale radio studies of tidal disruption events, im…
Exploring the Limits of Spectral Line Stacking in Spectral Line Data and Application Toward the Detection of Bulk C Enrichment of Aromatics in TMC-1
Miya Duffy, Ryan A. Loomis, Martin S. Holdren +9
The paper evaluates spectral line stacking and matched‑filter techniques to detect faint 13C‑substituted aromatic molecules in the cold cloud TMC‑1, demonstrating the method’s abil…
Relativistic effects of PSR~J1856--0039 double neutron star system in a 2.36-hour compact orbit
Z. L. Yang, J. L. Han, W. Q. Su +11
The paper reports the discovery and detailed relativistic measurements of the compact double neutron star system PSR J1856–0039, which has a 2.36‑hour orbit and the lowest total ma…
Global 21cm Measurement Calibration Methodology
Martin Bucher, Christian J. Kirkham, Eloy de Lera Acedo +2
The paper derives explicit calibration equations for global 21 cm signal experiments, reconciling earlier approaches with amplifier noise formalism and providing a Möbius‑geometry…
