Well done. You've clicked the tower. This would actually achieve something if you had logged in first. Use the key for that. The name takes you home. This is where all the applicables sit. And you can't apply any changes to my site unless you are logged in.

Our policy is best summarized as "we don't care about _you_, we care about _them_", no emails, so no forgetting your password. You have no rights. It's like you don't even exist. If you publish material, I reserve the right to remove it, or use it myself.

Don't impersonate. Don't name someone involuntarily. You can lose everything if you cross the line, and no, I won't cancel your automatic payments first, so you'll have to do it the hard way. See how serious this sounds? That's how serious you're meant to take these.

Velocity Distribution of Dark Matter Spike around Schwarzschild Black Holes and Effects on Gravitational Waves from EMRIs

arXiv:2403.18529v1 Announce Type: cross
Abstract: Dark matter (DM) constitutes the predominant portion of matter in our universe. Despite compelling evidence, the precise characteristics of DM remain elusive. Among the leading DM candidates are weakly interacting massive particles, which may aggregate into steep concentrations around the central black holes of galaxies, forming dense spikes. Employing Schwarzschild geometry, we assess the density and velocity distribution of DM within such spikes. Through variations in black hole masses and dark halo parameters, we identify universal features in the density profile of DM and fit them with Gaussian distributions. Additionally, we investigate the impact of dynamical friction on gravitational waves (GWs) generated by extreme-mass-ratio inspirals (EMRIs) within DM spikes. Our findings uncover phase shifts in the time-domain waveform, potentially providing significant insights for the GW-based detection of DM in galactic centers.
