Astrometric properties of reference frame sources as a function of redshift
Zhiyun Zhang, N. Liu, Xiaxuan Zhang +8
Previous studies based on the latest realisation of the International Celestial Reference Frame (ICRF3) have suggested a correlation between astrometric properties (such as the rad…
Stability of equilibrium points in modified elliptic restricted three-body problem with various perturbation sources
M. B. Saputra, H. S. Ramadhan, Ibnu N. Huda +1
This study examines the dynamics of the third body in an elliptic restricted three-body problem (ERTBP) framework, taking into account perturbations from radiation pressure, oblate…
Orbital dynamics and spin-precession around a circular chiral vorton
S. M. Holme, H. S. Ramadhan, I. Nurul Huda +1
Vortons are of interest in high-energy physics as possible dark matter candidates and as probes of Grand Unified Theories. Using the recently derived weak-field metric for a chiral…
Stellar Mass Assembly History of Massive Quiescent Galaxies since : Insights from Spatially Resolved SED Fitting with JWST Data
Novan Saputra Haryana, Masayuki Akiyama, Abdurro'uf +12
Massive quiescent galaxies at high redshift show significantly more compact morphology than their local counterparts. To examine their internal structure across a wide redshift ran…
