Inside an X-ray binary
Zoom from the whole binary to the black hole, and find the signals we'd actually see from Earth.
From: the QPO and heartbeat models in a ray tracer I wrote in Python (not public yet).

Toys from my papers
These are interactive toys built from my papers and code. Each one runs in your browser, and each has notes underneath on what it leaves out and where the numbers come from.
Take its pulse
Find out if the disc really heats up and cools down every beat.
From: the GRS 1915+105 heartbeat paper, ApJ 1007, 64 (2026).

Spot the binary
Find the quasars that hide a real pair of black holes, without falling for the fakes.
From: the cross-band periodicity paper, ApJ 1009, 184 (2026).

The fit that can't tell
Put a small error in a simulated X-ray detector's energy scale and watch the spectral fit absorb it.
From: the X-ray inference preprint, arXiv:2606.17098.

The chirp
Follow a pair of black holes to the merger and see which detector could hear it.
From: my smbhb-inspiral repo, a post-Newtonian inspiral simulator.
