   From http://status.hackerposse.com/url/24615 on Mastodon: These are my personal notes from day one of the Topics in Astroparticle and Underground Physics Conference. The full conference materials are online: http://status.hackerposse.com/url/24616 August 27, 2023 The rhythm of the TAUP conference is to have plenary sessions in the morning, followed by a lunch break, then …

   Jet-lagged for sure, but what a wonderful time in # Vienna last week! I am working on my personal summaries of the conference, so watch https:// steve.cooleysekula.net/blog for posts over the next week. They will be geared toward a # physics audience, but if anyone sees anything that they are # curious about, message me here! https://chirp.cooleysekula.net/attachment/4a9af7d058501338dee63b832fc36ab46cb55f6e2c40c84510fb17be87a20db6/view

   A view from the plane as we departed # Vienna this morning. I am getting my muscle memory back when it comes to this intercontinental travelling. https://chirp.cooleysekula.net/attachment/2a5b82da1a1911de0b96bb094155a909030708343e4da9193a38be76f29a4696/view

   Had a pretty uneventful flight from # Frankfurt to # Vienna . Waiting for my final connection to # Sudbury . Pretty easy trip overall. Did some coding on the plane, watched # DunePartOne , napped... and met some nice folks from Owen Sound!

    I am on my way home to # Canada from # Vienna . Currently on a short layover in # Frankfurt . # Vienna was wonderful and the # TAUP2023 conference was amazing. Attached is a photo from the conference dinner, held in the city hall. It was a remarkable venue for dinner. https://chirp.cooleysekula.net/attachment/f52ae92bc0d5d74e96831fbf68c074b60f248309182c77f90483a8b32707ecd5/view

    The current age of # GravitationalWave astronomy is breathtaking. The next age will be mind blowing. Between # LISA and at least one large-scale ground-based # Laser # Interferometer , plus the # Pulsar Network and # Cosmic # Microwave # Background approaches, there will be coverage from the Planck scale/birth of the universe to the merging of # Sueprmassive # BlackHoles and even # Supernova explosions. # TAUP2023

    Had a great time presenting the # HALO Collaboration poster on a preliminary look at neutron multiplicity in "bursts" in our detector. A burst is a sequence of neutrons (3 or more) that lie within 3ms. Had great conversations with the people that stopped by the poster session today. Check out the poster: https:// indico.cern.ch/event/1199289/c ontributions/5445885/ https://chirp.cooleysekula.net/attachment/e9162da81a6467ce2dc81d7b9aaa07a6090af4dfd19690dd4eb0a43db96b8ed9/view

    I am really excited about the effort from experiments like # ANAIS and # COSINUS to definitely understand the "quenching factor" of sodium iodide crystals. NaI has appeared in many experiments, and increasingly in # darkmatter experiments. The QF relates energy in electrons (usually what you see in an experiment) to the energy of the original nuclear recoil. The QF is ess…

    Lessons from the # TAUP conference: 1. The fundamental nature of the neutrino, as a fermion, is a crucial goal … and one that continues to prove challenging. 2. The cosmic microwave background has at least two big questions left, and they are hard: what is the polar structure of the light itself, and what can gravitational microlensing of that light tell us about large-scale structure of the more recent universe?

    From vicgrinberg@mastodon.social on Mastodon: Want to know what my research is about? Follow this thread 🧵 based on a 10min talk I've drawn for a meeting. The talk was aimed at non-specialist space science colleagues (not the general public!). The slides were built up step by step, but I'm omitting this here

    From mcnees@mastodon.social on Mastodon: Katherine Johnson passed away in 2020, at the age of 101.

    Getting ready to depart # Toronto for # Vienna ! Had a nice afternoon in the airport enjoying decaf coffee and chamomile tea while reading up on dark matter "freeze-in", one of the theoretical mechanisms by which a population of dark matter would be locked into the universe after the Big Bang. https://chirp.cooleysekula.net/attachment/bbaadd1004672e7040446dce9ff8f36a289f5fa7d83cdf9929ec634cc84541db/view

    From jodi on Mastodon: Before leaving Whitby, I hand to make one last stop at the @WhitbyMuseum to see the Zeplin-III experiment that operated in the @BoulbyLab many years ago.
