Precision Cosmology with Strong Lensing Time Delays

This workshop aims to bring together researchers working on aspects of strong gravitational lensing related to time-delay cosmography, and will be held the same week as the annual face-to-face TDCOSMO Collaboration meeting. The workshop will focus on recent progress and future prospects in areas such as lens modeling, lensed supernovae, time-delay measurements, substructure studies, and synergies with current and upcoming facilities and datasets. We hope the meeting will foster in-depth discussions and new collaborations within the community.

Access

For overseas visitors, Tokyo is serviced by the Narita (NRT) and Haneda (HND) airports. Haneda is conveniently located close to downtown and is connected to the metro systems, while Narita is farther away and accessed via high-speed rail (either JR Narita Express or Keisei Skyliner) or airport bus.

Visitors who are new to Japan should consider buying a Suica or Pasmo. This is a pre-paid electronic fare card that can be used for trains, subways, and buses. It can be obtained at JR stations or the Tokyo monorail station at Haneda for a 500 yen deposit, which is refundable along with the remaining balance when you leave (see the web pages for details and restrictions). It can be recharged at train/subway stations. Suica/Pasmo can also be used at convenience stores and many restaurants.

To access the University of Tokyo Hongo Campus, the nearest subway/train stations are Hongo-sanchome (本郷三丁目), Todaimae (東大前), and Nezu (根津). There are also buses available from other stations a bit further away. The workshop venue (School of Science Building #4) is shown on the Google map embedded below.
