Proxy Caller Project Many disabled people in the U.S. can’t make phone calls because of disability. Our Congress members unfairly prioritize phone calls over emails or letters—but all of us deserve to be heard. The…

Plot from arXiv:2503.15613 The x-axis is gravitational radii in the range 5 to 9. The y-axis is black hole mass in the range 3.3 to 6.0 solar masses. There is a colour bar showing dimensionless spin in the range 0.3 to 0.9, the colour map cycles through the pride flag colours. On the plot, an arc from top left to middle bottom extends to middle top to right bottom, filled with the pride colour map from purple for spin = 0.3 to black for spin = 0.9 Additionally, three contours in the Trans-pride flag colours show the dynamical time for mass and radius. The pride colour map indicates where an oscillation at 22Hz can occur due to Lense-Thirring precession

I have _pride_ about this figure from my recent paper.

It shows the viable parameter space for Lense-Thirring precession at 22.5 Hz for a merger origin black hole disk system.

This is relevant to the claimed periodicity in the precursor to GRB211211A

6 novels, 2 translations of a 7th novel, and an obscure short story.

I just deleted my Meta apps. As a US expat, I struggle with this breaking of contact with family and old friends. Then I remind myself that I lived most of my life before social media and it was fine. Good to see some familiar faces here.
