Size distribution of virus laden droplets from expiratory ejecta of infected subjects
Scientific Reports, 2020 For rebooting economic activities in the ongoing COVID-19 pandemic scenario, it is important to pay detailed attention to infection transfer mechanisms during interaction of people in enclosed environments.

Late Time Afterglow Observations Reveal a Collimated Relativistic Jet in the Ejecta of the Binary Neutron Star Merger GW170817. [PDF]
Physical Review Letters, 2017 The binary neutron star (BNS) merger GW170817 was the first astrophysical source detected in gravitational waves and multiwavelength electromagnetic radiation.

Comparison of Topographic Roughness of Layered Deposits on Mars
Remote Sensing, 2023 Impact craters with layered ejecta deposits are widespread on Mars. Prevailing views suggest that such ejecta were formed due to the involvement of target water and/or water ice in the impact excavation and/or the post-deposition movement of the impact ...

Kilonova from post-merger ejecta as an optical and near-infrared counterpart of GW170817 [PDF]
, 2017 Recent detection of gravitational waves from a neutron star (NS) merger event GW170817 and identification of an electromagnetic counterpart provide a unique opportunity to study the physical processes in NS mergers.

Synchrotron Radiation from the Fast Tail of Dynamical Ejecta of Neutron Star Mergers [PDF]
Astrophysical Journal, 2018 We find, using high-resolution numerical relativistic simulations, that the tail of the dynamical ejecta of neutron star mergers extends to mildly relativistic velocities faster than 0.7c. The kinetic energy of this fast tail is ∼1047–1049 erg, depending

High Angular Resolution ALMA Images of Dust and Molecules in the SN 1987A Ejecta [PDF]
Astrophysical Journal, 2019 We present high angular resolution (∼80 mas) ALMA continuum images of the SN 1987A system, together with CO J = 2 1, J = 6 5, and SiO J = 5 4 to J = 7 6 images, which clearly resolve the ejecta (dust continuum and molecules) and ring (synchrotron ...

Dynamic simulations of projectile penetration into granular medium
Mechanical Engineering Journal, 2014 Dynamic FEM and DEM simulations are carried out to investigate dynamic penetration of a projectile into a target of granular medium. Spatial distribution and time dependence of ejecta are clarified together with their trajectories in medium.

Element Abundances in the Unshocked Ejecta of Cassiopeia A [PDF]
Astrophysical Journal, 2020 We analyze and model the infrared spectrum of the Cassiopeia A supernova remnant with the aim of determining the masses of various elements in the unshocked ejecta.

Evolutionary signatures in complex ejecta and their driven shocks [PDF]
Annales Geophysicae, 2004 We examine interplanetary signatures of ejecta-ejecta interactions. To this end, two time intervals of inner-heliospheric (≤1AU) observations separated by 2 solar cycles are chosen where ejecta/magnetic clouds are in the process of interacting to ...
