Does measuring a quantum object collapse the wave function even if the particle is not found in the position where it was measured?
The "collapse of the wave function" is a very unphysical concept: It was invented within the Copenhagen Interpretation by people who tried to make sense of Quantum Mechanics, and who ...

Does measuring a quantum object collapse the wave function even if the particle is not found in the position where it was measured?
We are talking about a statistical law here. The probability of finding the particle in region $[x+\Delta x]$:
$$
P(x < X < x+\Delta x)=|\psi(X)|^2\Delta x=w
$$
This means that, after performing ...

You write:
Properties of quantum objects are determined by a wave function.
Not exactly. The wavefunction represents the evolution of the system. Sometimes that evolution involves what is happening ...

What happens in the double slit experiment if the detector is close to the slits?
Bricmont (Quantum Sense and Nonsense, 2017, pp.22-23) explicitly says that the interference disappears if the slits and detector are too close, but the consensus appears to be the converse. I only add ...
