On stratifications and poset-stratified spaces
Lukas Waas, Jon Woolf, Shoji Yokura
A stratified space is a topological space equipped with a \emph{stratification}, which is a decomposition or partition of the topological space satisfying certain extra conditions.…
Multi-epoch X-ray spectral analysis of Centaurus A: revealing new constraints on iron emission line origins
Toshiya Iwata, Atsushi Tanimoto, Hirokazu Odaka +3
We conduct X-ray reverberation mapping and spectral analysis of the radio galaxy Centaurus A to uncover its central structure. We compare the light curve of the hard X-ray continuu…
Systematic Collapse of the Accretion Disc Across the Supermassive Black Hole Population
Scott Hagen, Chris Done, John D. Silverman +7
The structure of the accretion flow onto supermassive black holes (SMBH) is not well understood. Standard disc models match to zeroth order in predicting substantial energy dissipa…
Divergence functions of higher-dimensional Thompson's groups
Yuya Kodama
We prove that higher-dimensional Thompson's groups have linear divergence functions. By the work of Druţu, Mozes, and Sapir, this implies none of the asymptotic cones of has a…
Co-evolution of dust grains and protoplanetary disks II: structure and evolution of protoplanetary disks; an analytical approach
Yusuke Tsukamoto
In our previous study (Tsukamoto {\it et al.} 2023), we investigated formation and early evolution of protoplanetary disks with 3D non-ideal magnetohydrodynamics simulations consid…
The relationship of SMBHs and host galaxies at in the deep optical variability-selected AGN sample in the COSMOS field
Atsushi Hoshi, Toru Yamada, Mitsuru Kokubo +2
We present the study on the relationship between SMBHs and their host galaxies using our variability-selected AGN sample () constructed from t…
