Gravitational Light Deflection with SKA-VLBI and Its Application to Precision Tests of General Relativity
Y. J. Li, J. J. Li, Z. H. Lin +4
Experimental test of general relativity remains an ongoing endeavour. Radio astrometry provides a vital tool for precisely measuring the light deflection caused by the Sun, testing…
Compact Objects Revealed by SKA and SKA-VLBI
Z. H. Lin, Y. J. Li, C. J. Hao +4
Compact objects represent a crucial interdisciplinary frontier between astronomy and fundamental physics.The SKA/SKA-VLBI, with exceptional sensitivity (at Jy levels) and ultra…
XMM-Newton multi-year campaign on NGC 55 ULX-1: Resolving the wind and its variability with RGS
C. Pinto, S. Caserta, F. Barra +12
Winds are an important ingredient in the evolution of X-ray binary (XRB) systems, particularly those at high accretion rates such as ultra-luminous X-ray sources (ULXs), because th…
Crust composition and the Shallow Heat Source in KS 1731-260
R. Jain, E. F. Brown, H. Schatz +11
The presence of a strong shallow heat source of unknown origin in accreting neutron star crusts has been inferred by analyzing X-ray observations of their cooling in quiescence. We…
Calibrating the Color-Magnitude Relation of M Giants by Using Open Clusters
Xiaoyu Tang, Chaojie Hao, Jing Li +8
M giants, with their distinctive properties such as high luminosity, serve as excellent indicators for mapping the structure of the Milky Way. The distance to distant M giants can…
Kinematics of Young Stellar Objects Under Various Stellar Feedback
Longhui Yang, Dejian Liu, Chaojie Hao +6
Based on the Gaia Data Release 3 and APOGEE datasets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-form…
