I am a graduate student studying astrophysics at Princeton. I received my bachelor's in physics and mathematics from Caltech (2011).

My primary interest is in general relativistic magnetohydrodynamics simulations of black hole accretion.

comment Are Hubble Telescope Images in true color?
That explanation for "why are the original images in black and white" seems a bit odd. CCDs are inherently greyscale, and the as-yet-unattained holy grail of scientific imaging is for every pixel to report not just intensity but wavelength for every photon. As the previous paragraph alludes to, all digital cameras are also greyscale, but the camera automatically combines the filtered images according to the manufacturer's preset approximation for human vision.

comment How does the mathematical definition of drag reduce to Stokes or form drag?
That $C_\mathrm{d} \to 1$ as $\mathrm{Re} \to \infty$ is no surprise, since we are then in the ballistic regime and the fluid can be modeled as a collection of non-self-interacting particles reflecting off the object.

comment Is there a phase transition for degenerate matter?
The neutron star evidence you refer to is presumably Cas A (are there others?). Plots like the inset in Figure 3 of Shternin et al make a good case for superfluidity (insofar as one believes the models).
