The workshop will bring together experts in the theory and observation of different methods used in the Extragalactic Distance Scale, to discuss current research activities and prospects for a 1% determination of H0 within ten years.
The workshop will focus on:
- the absolute calibration of primary and secondary distance indicators (including Cepheids, TRGB, RR Lyrae, blue supergiants, SNe Ia, surface brightness fluctuations, the Tully-Fisher relation and the fundamental plane);
- theoretical advances in the modeling of distance indicators;
- alternative routes to H0 (such as BAO, lens time delays, and megamasers in the Hubble flow);
- the synergy between direct determinations of H0 and observations of the CMB and high-redshift SNe for the determination of cosmological parameters.
