      Comments Off on What PFS is doing recently?

It’s been a while since the last article, so we are going to report our activities last month. We all, both scientists and developers, were pretty busy last month. Firstly, we had two engineering observations in May 2024.The PFS project is in the final phase of development, aiming to start the scientific operation in the 2025A semester (i.e., February 2025),… Read more »

In parallel to the instrument development, the PFS project has been developing hard the science using it. We had the PFS science meeting in early March 2023 at Kavli IPMU (Japan), in the hybrid format with zoom. The PFS science team has been developing a huge survey plan to observe enormous numbers of galaxies and stars in order to study… Read more »

PFS Science Meeting was held at Columbia University in New York, USA from October 4 to 7, 2019. PFS Science Team conducts a meeting in which we intensively discuss what kind of observations should be made in the large survey observation using PFS about once a year (see our post for the last year’s meeting). In this meeting, technical topics… Read more »

PFS Science Working Group Meeting at Princeton University

      No Comments on PFS Science Working Group Meeting at Princeton University

The PFS Science Team has established a working group for each scientific objective and has vigorously discussed what interesting science cases are to exploit the strengths of PFS and how we optimize the survey observation accordingly (visit our past post and our official web site for more details about science objectives of the project). Based on these discussions we have developed an… Read more »

The PFS Science Team is now planning a large survey observation of the Universe using PFS. Three working groups have been discussing the plans to achieve their major scientific objectives: “Cosmology” research group to reveal the nature of dark matter, dark energy and neutrinos, “Galactic archeology” research group to reconstruct the history of the Milky Way Galaxy where we exist,… Read more »

What will be revealed with PFS?

      Comments Off on What will be revealed with PFS?

— From Masahiro Takada (IPMU) Today we would like to introduce what we can study with PFS! The PFS project aims at three major scientific objectives. One of them is cosmology, in particular the nature of the so-called dark energy that is causing an accelerating expansion of the Universe. Its discovery earned 2011 Novel Prize in Physics. However, the discovery… Read more »
