Thanks. A pupil ghost is a fixed feature that comes from multiple reflections of the diffuse background from the sky or the telescope pupil. It is seen in flat images when doing photometry

Hi. My name is abi. I was wondering if anyone knew how to remove pupil ghost from images using the rmpupil command in IRAF.

Now i heard it is possible for an electron in the tube of a television tube to travel across the tube at a speed faster than the speed of light. How can special relativity explain this?

as for the area of interest...am not really sure yet..but am thinking cosmology/stelar astrophysics...i want to go a bit deeper into the big bang theory... i feel there is something missing and i wish to explore it... but i just need the necessary maths and physics tools

so can AIMS teach me the maths fundamentals i need to know for astrophysics??...or do they teach masters level maths

i need a program that deals with the necessary skills in maths and physics for masters in astrophysics...for at most a year

thanks...but does AIMS cover all areas in mathematical physics...and a mathematical fundamentals needed for masters level astrophysics...because checking through the only ones relating to physics are statistical mechanics and harmonic analysis...

i think its because of the age...and the resources...am in Africa...Nigeria to be precise...and i want to do my education in the US because there are no good universities offering astrophysics here...that is why am asking if i was to do self study of all the fundamentals for masters in...

Hello everyone. I have a challenge that has been bothering me and i would welcome any advice i can get right now. I have a BSc in Industrial Physics with applied Geophysics option. The problem is i don't know have a full knowledge of university physics and mathematics...am not even sure of my...

i have three questions for the physics community 1. is time be a function of space or space be a function of time? 2. can we say that without space and time, there is no physics? 3. why has physics progressed from a fact based science to a "faith" based science?

thanks xristy. the text was very helpful

i am actually talking about the electric signals produced...can these signals be expessed mathematicaly...like how the ones from electrical devices are expressed...

Hello, i want to know if there is any way we can describe the way our brain transfers information using Quantum Information theory. I have been looking at Quantum Information theory for some time now and would want to know if it will ever be possible to transfer information directly from the...

if actually the universe is a big computer simulation, who/what is controlling it? Simulation does not happen on its own...or do they??

ok...the equation is a groundwater flow equation...which is T*(d squared h/dx squared +d squared h/dy squared) +N=S*dh/dt...where s is storativity N is recharge and T is Transmissivity. i tried entering this and it returned it as output...actually this can be solved using FEM/FDM but how can...
