Systematic KMTNet Planetary Anomaly Search. XIII. Complete Sample of 2021 Prime Field Planets
In-Gu Shin, Jennifer C. Yee, Weicheng Zang +40
The Systematic KMTNet Planetary Anomaly Search series was conducted using the KMTNet data archived from to . From this first phase of the series, we reported a total o…
Magnetised CGM Gas at z~1 revealed by SPICE-RACS
Sunil Malik, S. P. O'Sullivan, A. J. M. Thomson +17
Magnetic fields are expected to permeate the circumgalactic medium (CGM) of galaxies, yet direct constraints at high redshift remain limited by the lack of high-quality Faraday rot…
A Vertically Orientated Dark Matter Halo Marks a Flip of the Galactic Disk
Ling Zhu, Runsheng Cai, Xi Kang +5
Unveiling the 3D shape of the Milky Way's dark-matter halo is critical to understanding its formation history. We created an innovative dynamical model with minimal assumptions on…
Uncover 3D Dark Matter Distribution of the Milky Way by an Empirical Triaxial Orbit-Superposition Model: Method Validation
Ling Zhu, Xiang-Xiang Xue, Shude Mao +2
We introduce a novel dynamical model, named empirical triaxial orbit-superposition model, for the Milky Way halo. This model relies on minimal physical assumptions that the system…
Recovering the pattern speeds of edge-on barred galaxies via an orbit-superposition method
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +4
We developed an orbit-superposition method for edge-on barred galaxies and evaluated its capability to recover the bar pattern speed . We selected three simulated galaxies…
Dynamical Models of the Milky Way in Action Space with LAMOST DR8 and GAIA EDR3
Guang-Chen Sun, Qiao Wang, Shude Mao +6
This work explores dynamical models of the Milky Way (MW) by analyzing a sample of 86,109 K giant stars selected through cross-matching the LAMOST DR8 and Gaia EDR3 surveys. Our ea…
