it still doesn't cover the bullet cluster, its certainly a very neat idea (worth looking into more id say) but we can clearly see here that the gas has collided and the galaxies have passed through each other, yet the weak lensing is around the stars, hence that's where the mass is. I am pretty...
Homework Statement
Hi, i have 2 past exam questions that i need to be able to solve for my exam in 3 days time:
consider the portion of a stellar wind of mass density rho, pressure p, temperature T and velocity v between the radii r=R_i = 10R_* and r=R_o = 100R_* where R_* is the radius...
nobody has done this. Instruments will probably never be sensitive enough but there is not much point anyway, its a reasonably well understood process, the reactions are simulated with particle accelerators
