I attended the XXII edition of COSMO which took place in Aachen (Germany) from 1st to 6th of September and gathered more than 200 physicists from all over the world. Here a picture with all the attendees. I also gave a talk on “Particle dark matter searches through cross-correlations between gamma-rays and neutral hydrogen intensity mapping”.
The topics covered include Early Universe, Gravitational Waves and Black Holes, Dark Matter and Astroparticle Physics, CMB, Modified Gravity and Dark Energy.
