Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
星系合并 SMBH 恒星物体演化 多质量 直接N体模型
2023/11/13
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...
Tracing star formation in galaxies with molecular line and continuum observations
molecular line continuum observations
2014/12/23
We report our recent progress on extragalactic spectroscopic and continuum observations, including HCN(J=1–0), HCO+(J=1–0), and CN(N=1–0) imaging surveys of local Seyfert and starburst galaxies using ...
Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analysis to investigate these ...
Acoustic ray tracing in the atmosphere: with gravitational effect and attenuation considered
Acoustic ray tracing Dissipative dispersion relation Gravity effect Attenuation
2015/8/18
An acoustic ray tracing model is developed to take into account the impacts of gravitational field and realistic atmospheric attenuation. Ray tracing equations are deduced from the real part of the di...
VATdt: Visual Assessment of Cluster Tendency Using Diagonal Tracing
Clustering Dissimilarity Measures Data Visualization Clustering Tendency
2013/1/30
The visual assessment of tendency (VAT) technique, for visually finding the number of meaningful clusters in data, developed by J. C. Bezdek, R. J. Hathaway and J. M. Huband, is very useful, but there...
Tracing the structure of asymmetric molecules from high-order harmonic generation
Tracing the structure asymmetric molecules high-order harmonic generation
2014/5/28
We investigate high-order harmonic generation (HHG) from asymmetric molecules exposed to intense laser fields. We show that the emissions of odd and even harmonics depend differently on the orientatio...

Dissecting high-mass star-forming regions; tracing back their complex formation history
Dissecting high-mass star-forming regions complex formation history
2011/8/24
We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their absorption line spect...

Adaptive image ray-tracing for astrophysical simulations
Adaptive image ray-tracing astrophysical simulations
2011/1/11
A technique is presented for producing synthetic images from numerical simulations whereby the image resolution is adapted around prominent features. In so doing, adaptive image ray-tracing (AIR) impr...
A Ray-Tracing Algorithm for Spinning Compact Object Spacetimes with Arbitrary Quadrupole Moments. I. Quasi-Kerr Black Holes
black hole physics radiative transfer relativity
2010/12/21
We describe a new numerical algorithm for ray tracing in the external spacetimes of spinning compact objects characterized by arbitrary quadrupole moments. Such spacetimes describe non-Kerr vacuum sol...
The global dust SED: Tracing the nature and evolution of dust with DustEM
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
The Planck and Herschel missions are currently measuring the farIR-mm emission of dust, which combined with existing IR data, will for the first time provide the full SED of the galactic ISM dust emis...
A bias in cosmic shear from galaxy selection: results from ray-tracing simulations
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/22
We identify and study a previously unknown systematic effect on cosmic shear measurements, caused by the selection of galaxies used for shape measurement, in particular the rejection of close (blended...
