Active Particle Diffusion in Convection Roll Arrays
Pulak Kumar Ghosh, Fabio Marchesoni, Yunyun Li +1
We numerically investigated the Brownian motion of active Janus particles in a linear array of planar counter-rotating convection rolls at high Péclet numbers. Similarly to passive…
Binary Mixtures in Linear Convection Arrays
Pulak Kumar Ghosh, Yuxin Zhou, Yunyun Li +2
We numerically investigated the dynamics of a mixture of finite-size active and passive particles in a linear array of convection rolls. The interplay of advection and steric inter…
Location of a Sample of GeV and Optical Outbursts in the Jets of Blazars
Maitreya Kundu, Arit Bala, Saugata Barat +1
The exact location of the -ray emitting region in blazar jets has long been a matter of debate. However, the location has important implications about the emission processes, ge…
Sub-Day Timescale X-ray Spectral Variability of the TeV Blazars Mrk 421 and 1ES 1959+650
Susmita Das, Ritaban Chatterjee
We present X-ray spectra ( keV) of two high synchrotron-peaked blazars Mrk 421 and 1ES 1959+650 from simultaneous observations by the SXT and LAXPC instruments onboard \tex…
Diffusion Transients in Motility-Induced Phase Separation
Shubhadip Nayak, Poulami Bag, Pulak K. Ghosh +4
We numerically investigate normal diffusion in a two-dimensional athermal suspension of active particles undergoing motility-induced phase separation. The particles are modeled as…
Herrera Complexity and Shadows of Spherically Symmetric Compact Objects
Subhasis Nalui, Subhra Bhattacharya
In this work we investigate the effect of complexity factor on the formation of photon spheres for spherically symmetric compact objects. The complexity factor obtained from the or…
