The Only Gaijin in the Onsen
After living in Japan for about four months, we left in mid-December. We miss it already. One of the pleasures we discovered is the onsen, or hot spring. Originally referring to the natural volcanic springs themselves, and the villages around them, there are now onsens all over Japan. Many hotels have an onsen, and most…

Discovering Japan
My old friend Marc Weidenbaum, curator and writer of disquiet.com, reminded me, in his latest post, of the value of blogging. So, here I am (again). Since September, I have been on sabbatical in Japan, working mostly at QUP (International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles) at the KEK…

If you’re reading this, then you might realise that I haven’t posted anything substantive here since 2018, commemorating the near-end of the Planck collaboration. In fact it took us well into the covid pandemic before the last of the official Planck papers were published, and further improved analyses of our data continues, alongside the use…

Planck: Demographics and Diversity
Another aspect of Planck’s legacy bears examining. A couple of months ago, the 2018 Gruber Prize in Cosmology was awarded to the Planck Satellite. This was (I think) a well-deserved honour for all of us who have worked on Planck during the more than 20 years since its conception, for a mission which confirmed a…

(Almost) The end of Planck
This week, we released (most of) the final set of papers from the Planck collaboration — the long-awaited Planck 2018 results (which were originally meant to be the “Planck 2016 results”, but everything takes longer than you hope…), available on the ESA website as well as the arXiv. More importantly for many astrophysicists and cosmologists,…

Leon Lucy, R.I.P.
I have the unfortunate duty of using this blog to announce the death a couple of weeks ago of Professor Leon B Lucy, who had been a Visiting Professor working here at Imperial College from 1998. Leon got his PhD in the early 1960s at the University of Manchester, and after postdoctoral positions in Europe…

WMAP Breaks Through
·
It was announced this morning that the WMAP team has won the $3 million Breakthrough Prize. Unlike the Nobel Prize, which infamously is only awarded to three people each year, the Breakthrough Prize was awarded to the whole 27-member WMAP team, led by Chuck Bennett, Gary Hinshaw, Norm Jarosik, Lyman Page, and David Spergel, but…

The Chandrasekhar Mass and the Hubble Constant
·
The first direct detection of gravitational waves was announced in February of 2015 by the LIGO team, after decades of planning, building and refining their beautiful experiment. Since that time, the US-based LIGO has been joined by the European Virgo gravitational wave telescope (and more are planned around the globe). The first four events that…

More technical stuff, but I’m trying to re-train myself to actually write on this blog, so here goes… For no good reason other than it was easy, I have added a JSONfeed to this blog. It can be found at http://andrewjaffe.net/blog/feed.json, and accessed from the bottom of the right-hand sidebar if you’re actually reading this…
