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 How do black holes in merging galaxies find each other to merge?
A footnote with some other search terms: This is the final-parsec problem, and indeed many feel the solution is in dynamical friction. Though papers are still published on the topic, so some would say the details aren't 100% worked out.

I challenge you to see a flat piece of glass with an anti-reflective coating ;)

comment Is it feasible to detect light emitted from planet earth 2,000 years ago by reflection from an object situated 1000 light years away?
Do you have a citation to back up the claim that we have detected our own radio signals? I'm reasonably sure we couldn't detect our own radio signals even 1 ly away with even the most powerful radio telescopes.

comment Calculate loudness of sound: why am I getting contradictory answers?
I'm curious where you got the original 210-213 dB. I can't identify anything in either link that gives that intensity at 75 m.

comment Is it possible to produce images of pair production in home-made cloud chamber?
For the curious, the market rate for 1 $\mu\mathrm{Ci}$ of Co-60 (which seems to be the most one can have without a license, but the NRC's rules are too convoluted for me to be sure what they say) seems to be about \$80.

comment Thoughts on the ice cube from orbit problem
@parceval John's calculations assume an equilibrium of sorts, and deals only with thermodynamics. A large enough meteor will hit the ground long before thermally equilibrating, and (for km-sized objects and above) even before a sound wave can cross from the front of the object to the back, and so kinetics becomes more important.

Many hearing aids link to devices like phones and TVs through e.g. Bluetooth...

comment Open problems in string theory
As with any topic, there is a PhD thesis for you if and only if there is an adviser willing to take you on as a student in that topic. Open questions are irrelevant if no one in your university will mentor you in them, and questions that aren't famous make perfectly for perfectly good research under the right tutelage.

comment How many of the 230 crystallographic groups are realized in nature?
PCC2 (mentioned by akhmeteli as not being observed as of 1999) is not in the dropdown menu. Also "The list box does not contain all possible space groups, but only those represented in the database." Interpret that how you will.
