Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...

Decomposition of Galaxy Images and Galaxy Rotation Curves Mosenkov A.V.*^, Savchenko S.S.*, Sotnikova N.Ya.* ... The DECA (DEComposition Analysis) code is designed to investigate images of galaxies in an automatic regime (using the simple 'bulge+disc' model) as well as in manual mode for more detailed images and/or for multicomponent structures. ... The GRCF package was created for performing the galaxies rotation curve decomposition using the models of the bulge, the disc, and the dark halo. ...

... Gravitational wave search provides insights into galaxy evolution and mergers . ... galaxies . ... The Hubble Space Telescope found a galaxy that was completely formed within 480 million years of the Big Bang. How could gas and dust clouds condense into stars and organize themselves via gravity into an entire galaxy in less time than it takes the Milky Way to make two rotations? ... Galaxies like the Milky Way indeed could not have formed as a unit at such an early era after the Big Bang. ...

... According to modern views on the evolution and origin of stars, most of the stars are members of binary systems. ... After the second explosion, the pairs tend to break up and neutron stars and/or black holes fly apart. High velocities of radio pulsars are apparently largely due to this effect. ... For all possible pairs the probability of trajectory approach at small distances for the epoch, corresponding to the age of the younger pulsar have been evaluated. ...
