BLACK HOLE INSPIRALS. “Many of the astrophysical signatures may be observationally glaring—for instance, even in regions of parameter space where no electroweak corona forms, owing to magnetic fields that are still many orders of magnitude larger than even magnetars, their consequent electromagnetic emissions will be spectacular during binary inspirals.” https://link.aps.org/doi/10.1103/PhysRevD.103.023006 View in LinkedIn

BLACK HOLE BINARIES. “We consider binary inspirals of both magnetic and neutral, and magnetic and magnetic, black hole pairs. The electromagnetic emissions and the gravitational waveform evolution, along with interblack hole separation, display distinct features.” https://link.aps.org/doi/10.1103/PhysRevD.103.023006 View in LinkedIn

INTERESTING TRIVIA. “The monk Mumon ("No-gate"), in the thirteenth century, compiled forty-eight koans, following each with a commentary and a small "poem". This work is called "The Gateless Gate" or the Mumonkan ("No-gate barrier"). It is interesting to note that the lives of Mumon and Fibonacci coincided almost exactly: Mumon living from 1183 to 1260 in China, Fibonacci from 1180 to 1250 in Italy.” (Fibonacci sequence, such that each number is the sum of the two preceding ones). https://lnkd.in/dmfn9qW View in LinkedIn

GRANULAR SAND. “Granular media are known to exhibit a richer variety of density fluctuations under externally applied stress, especially a shear stress.” https://lnkd.in/dusKMKM View in LinkedIn

RESPONSE TO PAPER. “As for reactions, it's really a mixed bag. We've had very positive reactions from a small number of young aficionados of granular matter, who've thought our proposed analogy as `very, very interesting'. On the other hand, senior experts appear to be much less enthusiastic and even skeptical. This isn't surprising, given that in today's world people are concerned about their own niches, and losing even an inch of their domain to a group of novices isn't welcome. The paper isn't published yet, but the fight with reviewers is on, so lets see. With our best wishes, Partha (Majumdar).” View in LinkedIn

BLACK HOLE FORMATION. “A more realistic situation for appearance of trapped surfaces is gravitational collapse. Here, the stress-energy tensor vanishes outside the boundary of the collapsing body (assumed spherical for simplicity).” https://lnkd.in/dusKMKM View in LinkedIn

SAND LINKS TO THE COSMOS. “Similarly, aspects of the CMB spectrum like non-Gaussianity may also show up as a feature of granular media observed experimentally. All-in-all, the assay portends an interesting future.” https://lnkd.in/dusKMKM View in LinkedIn

FRAME BY FRAME. “The spatial symmetries of granular interactions are manifest in every frame of the gravity analogue.” https://lnkd.in/dusKMKM View in LinkedIn

FEARLESS THINKING. “Perhaps one can also turn the analogy on its head, and use granular matter physics to explore phenomena that are yet unobserved in real cosmology. An example would be the existence of primordial gravitational waves which in the real universe are still shrouded in mystery.” https://lnkd.in/dusKMKM View in LinkedIn
