Simulation of advective accretion flows around black holes under various outer boundary conditions
Rajiv Kumar, Seong-Jae Lee
We simulated various accretion disc structures with viscous hydrodynamic (HD) flow around a black hole (BH). We found that the structure of the accretion disc is significantly infl…
Purity of extremal rays of Betti cones
H. Ananthnarayan, Omkar Javadekar, Rajiv Kumar
Let be a standard graded algebra over an infinite field , and let and denote the rational c…
Powers of vertex cover ideals of Simplicial Trees
Bijender, Ajay Kumar, Rajiv Kumar
In , Herzog, Hibi, and Ohsugi conjectured that if is the cover ideal of a chordal graph, then is componentwise linear for all In 2022, Hà and Tuyl consid…
A new prospect for jet origin and spectral state transitions with three hybrid accretion flows around black holes
Rajiv Kumar, Ye-Fei Yuan
There is a very popular two-zone accretion disk model that the inner part of the non-advective Keplerian disk (Shakura-Sunyaev disk) can produce hot advection-dominated accretion f…
A simulation-free seismic survey design by maximizing the spectral gap
Yijun Zhang, Mathias Louboutin, Ali Siahkoohi +3
Due to the tremendous cost of seismic data acquisition, methods have been developed to reduce the amount of data acquired by designing optimal missing trace reconstruction algorith…
Radiative energy from a reconnection region around massive black hole
TianLe Zhao, Rajiv Kumar
In the previous numerical study, we find the blob formation and ejection in the presence of magnetic reconnection in the environment of the hot flow of the accretion disk. Based on…
